ROLLER CHAIN

Roller chain or bush roller chain is the type of chain drive most commonly used for transmission of mechanical power on many kinds of domestic, industrial and agricultural machinery, including conveyors, wire- and tube-drawing machines, printing presses, cars, motorcycles, and bicycles. It consists of a series of short cylindrical rollers held together by side links. It is driven by a toothed wheel called a sprocket. It is a simple, reliable, and efficient means of power transmission.

CONSTRUCTION OF THE CHAIN

Two different sizes of roller chain, showing construction.
There are 2 types of links alternating in the bush roller chain. The first type is inner links, having 2 inner plates held together by 2 sleeves or bushings CZPT which rotate 2 rollers. Inner links alternate with the second type, the outer links, consisting of 2 outer plates held together by pins passing through the bushings of the inner links. The “bushingless” roller chain is similar in operation though not in construction; instead of separate bushings or sleeves holding the inner plates together, the plate has a tube stamped into it protruding from the hole which serves the same purpose. This has the advantage of removing 1 step in assembly of the chain.

The roller chain design reduces friction compared to simpler designs, resulting in higher efficiency and less wear. The original power transmission chain varieties lacked rollers and bushings, with both the inner and outer plates held by pins which directly contacted the sprocket teeth; however this configuration exhibited extremely rapid wear of both the sprocket teeth, and the plates where they pivoted on the pins. This problem was partially solved by the development of bushed chains, with the pins holding the outer plates passing through bushings or sleeves connecting the inner plates. This distributed the wear over a greater area; however the teeth of the sprockets still wore more rapidly than is desirable, from the sliding friction against the bushings. The addition of rollers surrounding the bushing sleeves of the chain and provided rolling contact with the teeth of the sprockets resulting in excellent resistance to wear of both sprockets and chain as well. There is even very low friction, as long as the chain is sufficiently lubricated. Continuous, clean, lubrication of roller chains is of primary importance for efficient operation as well as correct tensioning.

LUBRICATION

Many driving chains (for example, in factory equipment, or driving a camshaft inside an internal combustion engine) operate in clean environments, and thus the wearing surfaces (that is, the pins and bushings) are safe from precipitation and airborne grit, many even in a sealed environment such as an oil bath. Some roller chains are designed to have o-rings built into the space between the outside link plate and the inside roller link plates. Chain manufacturers began to include this feature in 1971 after the application was invented by Joseph Montano while working for Whitney Chain of Hartford, Connecticut. O-rings were included as a way to improve lubrication to the links of power transmission chains, a service that is vitally important to extending their working life. These rubber fixtures form a barrier that holds factory applied lubricating grease inside the pin and bushing wear areas. Further, the rubber o-rings prevent dirt and other contaminants from entering inside the chain linkages, where such particles would otherwise cause significant wear.[citation needed]

There are also many chains that have to operate in dirty conditions, and for size or operational reasons cannot be sealed. Examples include chains on farm equipment, bicycles, and chain saws. These chains will necessarily have relatively high rates of wear, particularly when the operators are prepared to accept more friction, less efficiency, more noise and more frequent replacement as they neglect lubrication and adjustment.

Many oil-based lubricants attract dirt and other particles, eventually forming an CZPT paste that will compound wear on chains. This problem can be circumvented by use of a “dry” PTFE spray, which forms a solid film after application and repels both particles and moisture.

VARIANTS DESIGN

Layout of a roller chain: 1. Outer plate, 2. Inner plate, 3. Pin, 4. Bushing, 5. Roller
If the chain is not being used for a high wear application (for instance if it is just transmitting motion from a hand-operated lever to a control shaft on a machine, or a sliding door on an oven), then 1 of the simpler types of chain may still be used. Conversely, where extra strength but the smooth drive of a smaller pitch is required, the chain may be “siamesed”; instead of just 2 rows of plates on the outer sides of the chain, there may be 3 (“duplex”), 4 (“triplex”), or more rows of plates running parallel, with bushings and rollers between each adjacent pair, and the same number of rows of teeth running in parallel on the sprockets to match. Timing chains on automotive engines, for example, typically have multiple rows of plates called strands.

Roller chain is made in several sizes, the most common American National Standards Institute (ANSI) standards being 40, 50, 60, and 80. The first digit(s) indicate the pitch of the chain in eighths of an inch, with the last digit being 0 for standard chain, 1 for lightweight chain, and 5 for bushed chain with no rollers. Thus, a chain with half-inch pitch would be a #40 while a #160 sprocket would have teeth spaced 2 inches apart, etc. Metric pitches are expressed in sixteenths of an inch; thus a metric #8 chain (08B-1) would be equivalent to an ANSI #40. Most roller chain is made from plain carbon or alloy steel, but stainless steel is used in food processing machinery or other places where lubrication is a problem, and nylon or brass are occasionally seen for the same reason.

Roller chain is ordinarily hooked up using a master link (also known as a connecting link), which typically has 1 pin held by a horseshoe clip rather than friction fit, allowing it to be inserted or removed with simple tools. Chain with a removable link or pin is also known as cottered chain, which allows the length of the chain to be adjusted. Half links (also known as offsets) are available and are used to increase the length of the chain by a single roller. Riveted roller chain has the master link (also known as a connecting link) “riveted” or mashed on the ends. These pins are made to be durable and are not removable.

USE

Roller chains are used in low- to mid-speed drives at around 600 to 800 feet per minute; however, at higher speeds, around 2,000 to 3,000 feet per minute, V-belts are normally used due to wear and noise issues.
A bicycle chain is a form of roller chain. Bicycle chains may have a master link, or may require a chain tool for removal and installation. A similar but larger and thus stronger chain is used on most motorcycles although it is sometimes replaced by either a toothed belt or a shaft drive, which offer lower noise level and fewer maintenance requirements.
The great majority of automobile engines use roller chains to drive the camshaft(s). Very high performance engines often use gear drive, and starting in the early 1960s toothed belts were used by some manufacturers.
Chains are also used in forklifts using hydraulic rams as a pulley to raise and lower the carriage; however, these chains are not considered roller chains, but are classified as lift or leaf chains.
Chainsaw cutting chains superficially resemble roller chains but are more closely related to leaf chains. They are driven by projecting drive links which also serve to locate the chain CZPT the bar.

A perhaps unusual use of a pair of motorcycle chains is in the Harrier Jump Jet, where a chain drive from an air motor is used to rotate the movable engine nozzles, allowing them to be pointed downwards for hovering flight, or to the rear for normal CZPT flight, a system known as Thrust vectoring.

WEAR

 

The effect of wear on a roller chain is to increase the pitch (spacing of the links), causing the chain to grow longer. Note that this is due to wear at the pivoting pins and bushes, not from actual stretching of the metal (as does happen to some flexible steel components such as the hand-brake cable of a motor vehicle).

With modern chains it is unusual for a chain (other than that of a bicycle) to wear until it breaks, since a worn chain leads to the rapid onset of wear on the teeth of the sprockets, with ultimate failure being the loss of all the teeth on the sprocket. The sprockets (in particular the smaller of the two) suffer a grinding motion that puts a characteristic hook shape into the driven face of the teeth. (This effect is made worse by a chain improperly tensioned, but is unavoidable no matter what care is taken). The worn teeth (and chain) no longer provides smooth transmission of power and this may become evident from the noise, the vibration or (in car engines using a timing chain) the variation in ignition timing seen with a timing light. Both sprockets and chain should be replaced in these cases, since a new chain on worn sprockets will not last long. However, in less severe cases it may be possible to save the larger of the 2 sprockets, since it is always the smaller 1 that suffers the most wear. Only in very light-weight applications such as a bicycle, or in extreme cases of improper tension, will the chain normally jump off the sprockets.

The lengthening due to wear of a chain is calculated by the following formula:

M = the length of a number of links measured

S = the number of links measured

P = Pitch

In industry, it is usual to monitor the movement of the chain tensioner (whether manual or automatic) or the exact length of a drive chain (one rule of thumb is to replace a roller chain which has elongated 3% on an adjustable drive or 1.5% on a fixed-center drive). A simpler method, particularly suitable for the cycle or motorcycle user, is to attempt to pull the chain away from the larger of the 2 sprockets, whilst ensuring the chain is taut. Any significant movement (e.g. making it possible to see through a gap) probably indicates a chain worn up to and beyond the limit. Sprocket damage will result if the problem is ignored. Sprocket wear cancels this effect, and may mask chain wear.

CHAIN STRENGTH

The most common measure of roller chain’s strength is tensile strength. Tensile strength represents how much load a chain can withstand under a one-time load before breaking. Just as important as tensile strength is a chain’s fatigue strength. The critical factors in a chain’s fatigue strength is the quality of steel used to manufacture the chain, the heat treatment of the chain components, the quality of the pitch hole fabrication of the linkplates, and the type of shot plus the intensity of shot peen coverage on the linkplates. Other factors can include the thickness of the linkplates and the design (contour) of the linkplates. The rule of thumb for roller chain operating on a continuous drive is for the chain load to not exceed a mere 1/6 or 1/9 of the chain’s tensile strength, depending on the type of master links used (press-fit vs. slip-fit)[citation needed]. Roller chains operating on a continuous drive beyond these thresholds can and typically do fail prematurely via linkplate fatigue failure.

The standard minimum ultimate strength of the ANSI 29.1 steel chain is 12,500 x (pitch, in inches)2. X-ring and O-Ring chains greatly decrease wear by means of internal lubricants, increasing chain life. The internal lubrication is inserted by means of a vacuum when riveting the chain together.

Standards organizations (such as ANSI and ISO) maintain standards for design, dimensions, and interchangeability of transmission chains. For example, the following Table shows data from ANSI standard B29.1-2011 (Precision Power Transmission Roller Chains, Attachments, and Sprockets) developed by the American Society of Mechanical Engineers (ASME).

For mnemonic purposes, below is another presentation of key dimensions from the same standard, expressed in fractions of an inch (which was part of the thinking behind the choice of preferred numbers in the ANSI standard):

12 48 40 516
58 58 50 38
34 68 60 12
1 88 80 58

Notes:
1. The pitch is the distance between roller centers. The width is the distance between the link plates (i.e. slightly more than the roller width to allow for clearance).
2. The right-hand digit of the standard denotes 0 = normal chain, 1 = lightweight chain, 5 = rollerless bushing chain.
3. The left-hand digit denotes the number of eighths of an inch that make up the pitch.
4. An “H” following the standard number denotes heavyweight chain. A hyphenated number following the standard number denotes double-strand (2), triple-strand (3), and so on. Thus 60H-3 denotes number 60 heavyweight triple-strand chain.
 A typical bicycle chain (for derailleur gears) uses narrow 1⁄2-inch-pitch chain. The width of the chain is variable, and does not affect the load capacity. The more sprockets at the rear wheel (historically 3-6, nowadays 7-12 sprockets), the narrower the chain. Chains are sold according to the number of speeds they are designed to work with, for example, “10 speed chain”. Hub gear or single speed bicycles use 1/2″ x 1/8″ chains, where 1/8″ refers to the maximum thickness of a sprocket that can be used with the chain.

Typically chains with parallel shaped links have an even number of links, with each narrow link followed by a broad one. Chains built up with a uniform type of link, narrow at 1 and broad at the other end, can be made with an odd number of links, which can be an advantage to adapt to a special chainwheel-distance; on the other side such a chain tends to be not so strong.

Roller chains made using ISO standard are sometimes called as isochains.

What are the temperature limits for heavy-duty chains in extreme environments?

Heavy-duty chains are designed to perform well in a wide range of temperatures, but their temperature limits in extreme environments depend on the materials they are made from and the specific application.

Generally, heavy-duty chains can handle temperatures ranging from -20°C to 200°C (-4°F to 392°F) in standard operating conditions. However, in extreme environments, such as foundries, steel mills, or extremely cold regions, special high-temperature or low-temperature chains may be required.

For high-temperature applications, heavy-duty chains made from heat-resistant materials, such as alloy steels or stainless steels, can withstand temperatures above 200°C (392°F) without losing their structural integrity.

On the other hand, in extremely cold environments, heavy-duty chains made from low-temperature materials, like specific grades of carbon steel or nickel-plated chains, can maintain their strength and flexibility at temperatures as low as -40°C (-40°F) and even lower.

When operating heavy-duty chains in extreme environments, it is essential to consider factors such as thermal expansion, contraction, and possible lubrication challenges. Adequate lubrication is crucial to ensure smooth operation and to protect the chains from wear and corrosion caused by temperature variations.

In critical applications with extreme temperature conditions, consulting with chain manufacturers or industry experts can help determine the most suitable heavy-duty chain materials and configurations for the specific environment to ensure optimal performance and longevity.

ROLLER CHAIN

Roller chain or bush roller chain is the type of chain drive most commonly used for transmission of mechanical power on many kinds of domestic, industrial and agricultural machinery, including conveyors, wire- and tube-drawing machines, printing presses, cars, motorcycles, and bicycles. It consists of a series of short cylindrical rollers held together by side links. It is driven by a toothed wheel called a sprocket. It is a simple, reliable, and efficient means of power transmission.

CONSTRUCTION OF THE CHAIN

Two different sizes of roller chain, showing construction.
There are 2 types of links alternating in the bush roller chain. The first type is inner links, having 2 inner plates held together by 2 sleeves or bushings CZPT which rotate 2 rollers. Inner links alternate with the second type, the outer links, consisting of 2 outer plates held together by pins passing through the bushings of the inner links. The “bushingless” roller chain is similar in operation though not in construction; instead of separate bushings or sleeves holding the inner plates together, the plate has a tube stamped into it protruding from the hole which serves the same purpose. This has the advantage of removing 1 step in assembly of the chain.

The roller chain design reduces friction compared to simpler designs, resulting in higher efficiency and less wear. The original power transmission chain varieties lacked rollers and bushings, with both the inner and outer plates held by pins which directly contacted the sprocket teeth; however this configuration exhibited extremely rapid wear of both the sprocket teeth, and the plates where they pivoted on the pins. This problem was partially solved by the development of bushed chains, with the pins holding the outer plates passing through bushings or sleeves connecting the inner plates. This distributed the wear over a greater area; however the teeth of the sprockets still wore more rapidly than is desirable, from the sliding friction against the bushings. The addition of rollers surrounding the bushing sleeves of the chain and provided rolling contact with the teeth of the sprockets resulting in excellent resistance to wear of both sprockets and chain as well. There is even very low friction, as long as the chain is sufficiently lubricated. Continuous, clean, lubrication of roller chains is of primary importance for efficient operation as well as correct tensioning.

LUBRICATION

Many driving chains (for example, in factory equipment, or driving a camshaft inside an internal combustion engine) operate in clean environments, and thus the wearing surfaces (that is, the pins and bushings) are safe from precipitation and airborne grit, many even in a sealed environment such as an oil bath. Some roller chains are designed to have o-rings built into the space between the outside link plate and the inside roller link plates. Chain manufacturers began to include this feature in 1971 after the application was invented by Joseph Montano while working for Whitney Chain of Hartford, Connecticut. O-rings were included as a way to improve lubrication to the links of power transmission chains, a service that is vitally important to extending their working life. These rubber fixtures form a barrier that holds factory applied lubricating grease inside the pin and bushing wear areas. Further, the rubber o-rings prevent dirt and other contaminants from entering inside the chain linkages, where such particles would otherwise cause significant wear.[citation needed]

There are also many chains that have to operate in dirty conditions, and for size or operational reasons cannot be sealed. Examples include chains on farm equipment, bicycles, and chain saws. These chains will necessarily have relatively high rates of wear, particularly when the operators are prepared to accept more friction, less efficiency, more noise and more frequent replacement as they neglect lubrication and adjustment.

Many oil-based lubricants attract dirt and other particles, eventually forming an CZPT paste that will compound wear on chains. This problem can be circumvented by use of a “dry” PTFE spray, which forms a solid film after application and repels both particles and moisture.

VARIANTS DESIGN

If the chain is not being used for a high wear application (for instance if it is just transmitting motion from a hand-operated lever to a control shaft on a machine, or a sliding door on an oven), then 1 of the simpler types of chain may still be used. Conversely, where extra strength but the smooth drive of a smaller pitch is required, the chain may be “siamesed”; instead of just 2 rows of plates on the outer sides of the chain, there may be 3 (“duplex”), 4 (“triplex”), or more rows of plates running parallel, with bushings and rollers between each adjacent pair, and the same number of rows of teeth running in parallel on the sprockets to match. Timing chains on automotive engines, for example, typically have multiple rows of plates called strands.

Roller chain is made in several sizes, the most common American National Standards Institute (ANSI) standards being 40, 50, 60, and 80. The first digit(s) indicate the pitch of the chain in eighths of an inch, with the last digit being 0 for standard chain, 1 for lightweight chain, and 5 for bushed chain with no rollers. Thus, a chain with half-inch pitch would be a #40 while a #160 sprocket would have teeth spaced 2 inches apart, etc. Metric pitches are expressed in sixteenths of an inch; thus a metric #8 chain (08B-1) would be equivalent to an ANSI #40. Most roller chain is made from plain carbon or alloy steel, but stainless steel is used in food processing machinery or other places where lubrication is a problem, and nylon or brass are occasionally seen for the same reason.

Roller chain is ordinarily hooked up using a master link (also known as a connecting link), which typically has 1 pin held by a horseshoe clip rather than friction fit, allowing it to be inserted or removed with simple tools. Chain with a removable link or pin is also known as cottered chain, which allows the length of the chain to be adjusted. Half links (also known as offsets) are available and are used to increase the length of the chain by a single roller. Riveted roller chain has the master link (also known as a connecting link) “riveted” or mashed on the ends. These pins are made to be durable and are not removable.

Roller chains operating on a continuous drive beyond these thresholds can and typically do fail prematurely via linkplate fatigue failure.

The standard minimum ultimate strength of the ANSI 29.1 steel chain is 12,500 x (pitch, in inches)2. X-ring and O-Ring chains greatly decrease wear by means of internal lubricants, increasing chain life. The internal lubrication is inserted by means of a vacuum when riveting the chain together.

Notes:
1. The pitch is the distance between roller centers. The width is the distance between the link plates (i.e. slightly more than the roller width to allow for clearance).
2. The right-hand digit of the standard denotes 0 = normal chain, 1 = lightweight chain, 5 = rollerless bushing chain.
3. The left-hand digit denotes the number of eighths of an inch that make up the pitch.
4. An “H” following the standard number denotes heavyweight chain. A hyphenated number following the standard number denotes double-strand (2), triple-strand (3), and so on. Thus 60H-3 denotes number 60 heavyweight triple-strand chain.
 A typical bicycle chain (for derailleur gears) uses narrow 1⁄2-inch-pitch chain. The width of the chain is variable, and does not affect the load capacity. The more sprockets at the rear wheel (historically 3-6, nowadays 7-12 sprockets), the narrower the chain. Chains are sold according to the number of speeds they are designed to work with, for example, “10 speed chain”. Hub gear or single speed bicycles use 1/2″ x 1/8″ chains, where 1/8″ refers to the maximum thickness of a sprocket that can be used with the chain.

Typically chains with parallel shaped links have an even number of links, with each narrow link followed by a broad one. Chains built up with a uniform type of link, narrow at 1 and broad at the other end, can be made with an odd number of links, which can be an advantage to adapt to a special chainwheel-distance; on the other side such a chain tends to be not so strong.

Roller chains made using ISO standard are sometimes called as isochains.

ROLLER CHAIN

Roller chain or bush roller chain is the type of chain drive most commonly used for transmission of mechanical power on many kinds of domestic, industrial and agricultural machinery, including conveyors, wire- and tube-drawing machines, printing presses, cars, motorcycles, and bicycles. It consists of a series of short cylindrical rollers held together by side links. It is driven by a toothed wheel called a sprocket. It is a simple, reliable, and efficient means of power transmission.

CONSTRUCTION OF THE CHAIN

Two different sizes of roller chain, showing construction.
There are 2 types of links alternating in the bush roller chain. The first type is inner links, having 2 inner plates held together by 2 sleeves or bushings CZPT which rotate 2 rollers. Inner links alternate with the second type, the outer links, consisting of 2 outer plates held together by pins passing through the bushings of the inner links. The “bushingless” roller chain is similar in operation though not in construction; instead of separate bushings or sleeves holding the inner plates together, the plate has a tube stamped into it protruding from the hole which serves the same purpose. This has the advantage of removing 1 step in assembly of the chain.

The roller chain design reduces friction compared to simpler designs, resulting in higher efficiency and less wear. The original power transmission chain varieties lacked rollers and bushings, with both the inner and outer plates held by pins which directly contacted the sprocket teeth; however this configuration exhibited extremely rapid wear of both the sprocket teeth, and the plates where they pivoted on the pins. This problem was partially solved by the development of bushed chains, with the pins holding the outer plates passing through bushings or sleeves connecting the inner plates. This distributed the wear over a greater area; however the teeth of the sprockets still wore more rapidly than is desirable, from the sliding friction against the bushings. The addition of rollers surrounding the bushing sleeves of the chain and provided rolling contact with the teeth of the sprockets resulting in excellent resistance to wear of both sprockets and chain as well. There is even very low friction, as long as the chain is sufficiently lubricated. Continuous, clean, lubrication of roller chains is of primary importance for efficient operation as well as correct tensioning.

LUBRICATION

Many driving chains (for example, in factory equipment, or driving a camshaft inside an internal combustion engine) operate in clean environments, and thus the wearing surfaces (that is, the pins and bushings) are safe from precipitation and airborne grit, many even in a sealed environment such as an oil bath. Some roller chains are designed to have o-rings built into the space between the outside link plate and the inside roller link plates. Chain manufacturers began to include this feature in 1971 after the application was invented by Joseph Montano while working for Whitney Chain of Hartford, Connecticut. O-rings were included as a way to improve lubrication to the links of power transmission chains, a service that is vitally important to extending their working life. These rubber fixtures form a barrier that holds factory applied lubricating grease inside the pin and bushing wear areas. Further, the rubber o-rings prevent dirt and other contaminants from entering inside the chain linkages, where such particles would otherwise cause significant wear.[citation needed]

There are also many chains that have to operate in dirty conditions, and for size or operational reasons cannot be sealed. Examples include chains on farm equipment, bicycles, and chain saws. These chains will necessarily have relatively high rates of wear, particularly when the operators are prepared to accept more friction, less efficiency, more noise and more frequent replacement as they neglect lubrication and adjustment.

Many oil-based lubricants attract dirt and other particles, eventually forming an CZPT paste that will compound wear on chains. This problem can be circumvented by use of a “dry” PTFE spray, which forms a solid film after application and repels both particles and moisture.

VARIANTS DESIGN

Layout of a roller chain: 1. Outer plate, 2. Inner plate, 3. Pin, 4. Bushing, 5. Roller
If the chain is not being used for a high wear application (for instance if it is just transmitting motion from a hand-operated lever to a control shaft on a machine, or a sliding door on an oven), then 1 of the simpler types of chain may still be used. Conversely, where extra strength but the smooth drive of a smaller pitch is required, the chain may be “siamesed”; instead of just 2 rows of plates on the outer sides of the chain, there may be 3 (“duplex”), 4 (“triplex”), or more rows of plates running parallel, with bushings and rollers between each adjacent pair, and the same number of rows of teeth running in parallel on the sprockets to match. Timing chains on automotive engines, for example, typically have multiple rows of plates called strands.

Roller chain is made in several sizes, the most common American National Standards Institute (ANSI) standards being 40, 50, 60, and 80. The first digit(s) indicate the pitch of the chain in eighths of an inch, with the last digit being 0 for standard chain, 1 for lightweight chain, and 5 for bushed chain with no rollers. Thus, a chain with half-inch pitch would be a #40 while a #160 sprocket would have teeth spaced 2 inches apart, etc. Metric pitches are expressed in sixteenths of an inch; thus a metric #8 chain (08B-1) would be equivalent to an ANSI #40. Most roller chain is made from plain carbon or alloy steel, but stainless steel is used in food processing machinery or other places where lubrication is a problem, and nylon or brass are occasionally seen for the same reason.

Roller chain is ordinarily hooked up using a master link (also known as a connecting link), which typically has 1 pin held by a horseshoe clip rather than friction fit, allowing it to be inserted or removed with simple tools. Chain with a removable link or pin is also known as cottered chain, which allows the length of the chain to be adjusted. Half links (also known as offsets) are available and are used to increase the length of the chain by a single roller. Riveted roller chain has the master link (also known as a connecting link) “riveted” or mashed on the ends. These pins are made to be durable and are not removable.

USE

An example of 2 ‘ghost’ sprockets tensioning a triplex roller chain system
Roller chains are used in low- to mid-speed drives at around 600 to 800 feet per minute; however, at higher speeds, around 2,000 to 3,000 feet per minute, V-belts are normally used due to wear and noise issues.
A bicycle chain is a form of roller chain. Bicycle chains may have a master link, or may require a chain tool for removal and installation. A similar but larger and thus stronger chain is used on most motorcycles although it is sometimes replaced by either a toothed belt or a shaft drive, which offer lower noise level and fewer maintenance requirements.
The great majority of automobile engines use roller chains to drive the camshaft(s). Very high performance engines often use gear drive, and starting in the early 1960s toothed belts were used by some manufacturers.
Chains are also used in forklifts using hydraulic rams as a pulley to raise and lower the carriage; however, these chains are not considered roller chains, but are classified as lift or leaf chains.
Chainsaw cutting chains superficially resemble roller chains but are more closely related to leaf chains. They are driven by projecting drive links which also serve to locate the chain CZPT the bar.

A perhaps unusual use of a pair of motorcycle chains is in the Harrier Jump Jet, where a chain drive from an air motor is used to rotate the movable engine nozzles, allowing them to be pointed downwards for hovering flight, or to the rear for normal CZPT flight, a system known as Thrust vectoring.

WEAR

 

The effect of wear on a roller chain is to increase the pitch (spacing of the links), causing the chain to grow longer. Note that this is due to wear at the pivoting pins and bushes, not from actual stretching of the metal (as does happen to some flexible steel components such as the hand-brake cable of a motor vehicle).

With modern chains it is unusual for a chain (other than that of a bicycle) to wear until it breaks, since a worn chain leads to the rapid onset of wear on the teeth of the sprockets, with ultimate failure being the loss of all the teeth on the sprocket. The sprockets (in particular the smaller of the two) suffer a grinding motion that puts a characteristic hook shape into the driven face of the teeth. (This effect is made worse by a chain improperly tensioned, but is unavoidable no matter what care is taken). The worn teeth (and chain) no longer provides smooth transmission of power and this may become evident from the noise, the vibration or (in car engines using a timing chain) the variation in ignition timing seen with a timing light. Both sprockets and chain should be replaced in these cases, since a new chain on worn sprockets will not last long. However, in less severe cases it may be possible to save the larger of the 2 sprockets, since it is always the smaller 1 that suffers the most wear. Only in very light-weight applications such as a bicycle, or in extreme cases of improper tension, will the chain normally jump off the sprockets.

The lengthening due to wear of a chain is calculated by the following formula:

M = the length of a number of links measured

S = the number of links measured

P = Pitch

In industry, it is usual to monitor the movement of the chain tensioner (whether manual or automatic) or the exact length of a drive chain (one rule of thumb is to replace a roller chain which has elongated 3% on an adjustable drive or 1.5% on a fixed-center drive). A simpler method, particularly suitable for the cycle or motorcycle user, is to attempt to pull the chain away from the larger of the 2 sprockets, whilst ensuring the chain is taut. Any significant movement (e.g. making it possible to see through a gap) probably indicates a chain worn up to and beyond the limit. Sprocket damage will result if the problem is ignored. Sprocket wear cancels this effect, and may mask chain wear.

CHAIN STRENGTH

The most common measure of roller chain’s strength is tensile strength. Tensile strength represents how much load a chain can withstand under a one-time load before breaking. Just as important as tensile strength is a chain’s fatigue strength. The critical factors in a chain’s fatigue strength is the quality of steel used to manufacture the chain, the heat treatment of the chain components, the quality of the pitch hole fabrication of the linkplates, and the type of shot plus the intensity of shot peen coverage on the linkplates. Other factors can include the thickness of the linkplates and the design (contour) of the linkplates. The rule of thumb for roller chain operating on a continuous drive is for the chain load to not exceed a mere 1/6 or 1/9 of the chain’s tensile strength, depending on the type of master links used (press-fit vs. slip-fit)[citation needed]. Roller chains operating on a continuous drive beyond these thresholds can and typically do fail prematurely via linkplate fatigue failure.

The standard minimum ultimate strength of the ANSI 29.1 steel chain is 12,500 x (pitch, in inches)2. X-ring and O-Ring chains greatly decrease wear by means of internal lubricants, increasing chain life. The internal lubrication is inserted by means of a vacuum when riveting the chain together.

CHAIN STHangZhouRDS

Standards organizations (such as ANSI and ISO) maintain standards for design, dimensions, and interchangeability of transmission chains. For example, the following Table shows data from ANSI standard B29.1-2011 (Precision Power Transmission Roller Chains, Attachments, and Sprockets) developed by the American Society of Mechanical Engineers (ASME). See the references[8][9][10] for additional information.

buy drive chain

Buying a drive chain requires a certain understading of its characteristics. This article discusses the different types of chains available, including Silent, Flat-top, and Duplex. By the end of this article, you should have a basic understanding of what each type of chain is for. First, here are some basic rules to keep in mind when shopping for a chain. To find the drive chain that best suits your needs, read on.

roller chain

Choosing the right roller chain for your drive chain depends on several factors. First, you have to determine the motor horsepower and rpm for the small drive sprocket. These values ​​determine the size of the chain and the number of teeth on the drive sprocket. Next, you need to determine the size of the conveyor chain, it can be the horizontal, vertical, or curved radius. Depending on your specific needs, you can also choose between two-strand or three-strand chains.
The roller chain of the drive chain must be properly tensioned. It should also have a proper lubrication system. Chain sag should not exceed two to four percent of the center distance (the distance between the two axles). Also, it shouldn’t make any unusual noises or obvious problems. One of the main reasons for excessive wear is the size of the load. Each chain has a specified maximum working load.
The maximum roller chain load must be less than 1/9 or 6 times the tensile strength of the drive chain. This amount should not exceed this threshold, as exceeding this level will result in chain plate fatigue. To avoid this, you should use a roller chain with a higher number of strands. Also, for high power requirements, a roller chain with a higher number of strands is recommended. One final tip for choosing a drive chain: it should not be used when there is a high risk of corrosion or rusting.
The materials used to manufacture roller chains vary according to the specific application. Common materials include steel and stainless steel. However, stainless steel is used in food processing machinery and other environments that require lubrication. Brass and nylon are also sometimes used. These factors determine the selection of suitable materials for the drive chain. If you are not sure which material to use, you can consult an industry professional. These professionals will help you choose the right chain for the job at hand.

mute chain

The design of the silent transmission chain is as follows: the large chain plates 2 are stacked one on top of the other in the direction of the chain length. The connecting rods are connected by connecting pins 3. The outermost and central guide plates 4 are fastened to the connecting pins 3 by means of rivets. This construction helps minimize friction on the sliding surfaces of the chain. Chainplate 2 of the silent transmission chain is usually made of stainless steel.
The link plates are made of steel and have a rectangular shape with pinholes 41. These guide plates have no teeth but have curved surfaces that guide the silent drive chain on the sprockets. In addition, the rear portion of the guide plate is higher than the portion of the chainplate. This feature improves pitch balance. The present invention is also applicable to silent transmission chains using rockers.
When it comes to chain design, it’s important to remember that silent drive chains are often used in automotive engines, especially timing and cam drives. This type of drive reduces noise and vibration due to its low engagement angle and links engagement with the sprocket. However, these applications are not limited to timing and cam drives; they can also be used for front-wheel power transmission. For example, silent drive chains are designed to resemble those used in NASCAR racing engines.
The design of the silent drive chain is based on the structure of the roller chain. Its components are standardized and manufactured according to pitch. There are single-row and multi-row versions. Quiet chains, also known as inverted tooth chains, are shaped to reduce noise from stretching. It’s also designed to minimize the amount of friction caused by small changes in pitch. Its teeth don’t slide against each other, so the chain is smoother and more durable.

flat top chain

One of the important parts of the flat top chainplate system is the hinge pin, which is used to fix the chainplate and is responsible for the smooth and efficient conveying of the chainplate. There are several types of hinge pins, including single hinge pins and double hinge pins. The single hinge pin is suitable for the chainplate with a small span and small bearing capacity, and the double hinge pin is suitable for the chainplate with a large span and high bearing capacity.
The side bending flat top chain is suitable for conveying large and medium workpiece pallets. They can be made of steel or plastic, each with its own advantages. Both chainplates are designed to convey material smoothly. Side curved flat-top chains can be used on straight conveyors. They have a low coefficient of friction and can transport weights up to 1.2 kg/cm. They can also be combined with HD profiles.
Flat top drive chains are usually made of plastic material and come in two types: tabletop chains and buffer chains. They come in a variety of widths, but the most popular are standard widths, ranging from 3.25 inches to 12 inches. MatTop chains are usually shipped in 10-foot lengths. They come in different styles, but they all have the same basic specs. Tabletop chains are designed for general conveying, while pad chains are used for specific applications. Solid top chains are suitable for conveying bulk materials, while wide pad chains can handle large volumes of fluids and/or solid-solid mixtures.
These chain conveyors can be used to convey, connect or lift small items. This type of chain is especially useful in industries where the product is hot or greasy. The modular design of these chains allows them to be configured in three dimensions, making them suitable for production changes and transitions. They also help reduce slack in the chain. Flat top chains are commonly used in final assembly and mechanical or paint restoration in the automotive industry.

double chain

Besides the roller chain, another type of chain drive is the double drive chain. This type of chain consists of a series of short cylindrical rollers connected together by side links and driven by gears called sprockets. This type of chain is very reliable and only requires a tractor with a high rpm PTO. It is manufactured by CZPT and is available in many different sizes and finishes.

Self-lubricating chain

Self-lubricating drive chains are the ideal solution for applications that do not require the relubrication of conventional chains. This maintenance-free roller chain features fully heat-treated components that increase the chain’s fatigue resistance and strength. It’s sintered alloy bushings are oil-impregnated, reducing the chance of premature wear and elongation. Its self-lubricating properties enhance its durability and work well even in hard-to-reach places.
CZPT self-lubricating roller chains feature preloaded sintered steel bearing pins and oil-impregnated sintered bushings. These chains are drop-in replacements for standard roller chains and run on the same sprockets as standard chains. In addition to being maintenance-free, self-lubricating roller chains are compatible with most existing sprockets and are ideal for demanding applications.
The O-ring chain concept was used to develop self-lubricating systems. It has two or more annular grease storage chambers. A self-lubricating bushing roller chain has an oil reservoir between its pin chain and the roller chainplate. A grease seal between these two plates isolates the moving parts and keeps the joints well lubricated. O-rings are made of special nitrile rubber, whose properties vary by application.
CZPT SLR conveyor chains and CZPT SLR drive chains have rollers on sintered bushings. CZPT SLR chains and SLR conveyor chains are self-lubricating and have a higher working load than standard ANSI chains. They may not be interchangeable with other self-lubricating chains from other manufacturers. Self-lubricating drive chains are the best solution for demanding industrial applications requiring heavy-duty, reliable conveying.

Self-lubricating chain

Self-lubricating roller chains are designed to increase performance while maintaining a high level of cleanliness. These chains are made of sintered alloy bushings impregnated with lubricant and pins specially treated to release oil when necessary. These chains have a long service life and are suitable for environments where regular lubrication is difficult. Below are the benefits of self-lubricating roller chains.
Maintenance-free self-lubricating roller chains are the perfect replacement for standard roller chains. They are suitable for packaging, printing, textile, and sawmill applications. These chains reduce downtime and increase productivity. Furthermore, they reduce the risk of contamination. Another advantage is that there are many types of self-lubricating roller chains to choose from, allowing you to choose the one that best suits your needs. To learn more about these benefits, read the Maintenance Free Roller Chains Market Report published by Dataintelo.
CAN-AM self-lubricating roller chains ensure stick-free operation. These chains are available in ANSI/BS standard and double pitch variants. They feature oil-impregnated bushings and preloaded sintered steel bushings for long life. These self-lubricating roller chains are drop-in replacements for standard roller chains and run on standard roller chain sprockets.<br/

X-Ring and O-Ring Chains

Both O-ring and X-ring roller chains are sealed and unsealed. You’ll find them on vintage bikes and small economy cars. Other applications include bulldozer treads and conveyor belts. Standard chains are made of simple plain bearings that require lubrication every few hundred miles. While the former is the most affordable type of roller chain, they do require more maintenance than O-rings.
The main difference between the two types of chains is the friction and cost they generate. X-rings are slightly less expensive, but they create less friction than O-rings. X-rings are a more affordable option for road riders, while O-ring chains are more expensive for off-road racers. In some cases, X-ring and O-ring roller chains can be distinguished by the price tag alone.
Both X-ring and O-ring roller sprockets are available in a variety of styles. The two styles offer comparable performance, but there are some key differences to consider. X-rings are generally better for longer travel as they offer greater durability and performance. O-rings are usually more expensive than X-ring chains, but if you’re thinking about long trips, they’re a great option.

Reverse chain

Inverted roller chains are often referred to as silent chains. They have two protrusions on each board. The outer surface is ground to include an angle of sixty or seventy degrees. These protrusions about the working surfaces of the sprocket teeth. The inner surface or shape of the sprocket can clear the sprocket. This produces a silent but still valid chain. This type of chain is used in transmissions to move heavy objects.
There are three basic types of inverted toothed roller chains. Simple chains are single chains, while double and triple chains have two or three strands. In these types of chains, the pins pass through-hardened steel bushings at the ends of the links. The main difference between these types is their size. If you are not sure what size you need, first calculate the capacity of the chain. You might be surprised to learn that the smaller the diameter the better.
The number of links in a reverse roller chain determines the frequency of vibration. The frequency depends on the size of the chain and the length of the chain between the sprockets. The shorter the chain, the bigger the “pull” – the up-and-down jitter caused by the sprocket. This causes additional peak loads on the drive and shortens its life.

PEER Chain’s Heavy Duty Series Double-Stranded Roller Chains

Heavy-duty double-strand roller chains are ideal for industrial and agricultural use as they provide extra stability and strength. PEER Chains manufactures chains in various lengths and pitches and offers different accessories including sprockets and pre tensioned chains.

Maintenance of Mechanical Flexible Couplings

Proper maintenance of mechanical flexible couplings on roller chains is critical to ensuring the proper operation and reliability of the system. Maintenance of these couplings includes periodic inspection of the components. Check for signs of fatigue and wear. Regular inspections will help determine when to replace the coupling. It also helps determine the remaining life of the coupling.
Couplings should be replaced periodically for optimum performance. When replacing, be sure to use the correct parts. Make sure the coupling type matches the coupling type and chain size. Identical coupling parts may not fit, so a cross-reference guide or manufacturer’s spec number may be helpful. Make sure that the coupling is fitted with a suitable roller chain.
Mechanical elastic couplings on the roller chain can be easily lubricated to avoid premature failure. Elastomeric couplings can accommodate minor shaft misalignments and are suitable for high rotational speeds. Also, it absorbs shocks. Its flexibility is due to loose components. Additionally, lubrication is essential to reduce wear on coupling components.
chain

Roller chain size

Knowing the basic dimensions of the rollers is essential if you need to find the right roller chain for your needs. The three key dimensions of a roller chain are pitch, width, and pin diameter. These dimensions are important because they are used to identify the type of chain. These dimensions do not normally appear in chain manufacturer catalogs. They are usually designed for people designing new equipment. They are not important to maintenance technicians, but they are important to know if you are looking for a specific type of roller chain.
Once you know the exact size of the chain, you can move on to choosing the correct type. You can use the printable template to measure your chain, which makes it easy to compare with the size chart. Don’t forget to check the rest of the roller chain’s specs to make sure it fits your machine. Using the Roller Chain Size Chart is an easy way to determine the proper length, width, and height for your application.
When buying a roller chain, be sure to check the number of teeth and the ratio of the two. A common ratio is 2:1. The drive sprocket must have at least twice as many teeth as the roller sprocket. If the chain is used for high precision, check the type of sprocket as this will determine the correct size of the chain. You can also choose between slip-fit ​​and press-fit mid plates.

What is a drive chain?

A drive chain is a wheeled device that transmits power from one gear to another. The drive chain is usually an oval ring around a corner or worm gear. On the other hand, idler pulleys do not transmit power and are not used to move the chain. In some cases, drive chains can be used with idler pulleys to transport objects. This allows the drive chain to recover some power from the second gear.

conveyor chain

There are many types of conveyor chains to choose from. One type is a closed joint chain. It consists of the barrel and connecting rod, made from a single casting and heat-treated for high strength and durability. Conveyor chains typically have low running speeds and are typically made of malleable iron. Another type of chain is the power transmission chain, which is used to transmit mechanical power. They feature efficient lubrication and are stronger than conventional conveyor chains.
Roller chain pitches can range from half an inch to a third of an inch. They are available in steel and nickel-plated steel. They can be used with inline or staggered rollers and can be designed with different pitch levels. They can also have bushings between the chainplates or gaps between the teeth to increase their maximum spacing. When choosing a conveyor chain, remember to properly lubricate bearing surfaces to minimize power absorption, wear, and corrosion. Mineral oils of medium viscosity are suitable for normal operating temperatures. SAE 20W50 is suitable. Manufacturers also offer self-lubricating chains.
Conveyor chains are used in many industries. The automotive industry has traditionally used these chains for bulk transport. Their reliability and low cost make them an excellent choice for a variety of applications. CZPT Chains offers stainless steel and CZPT conveyor chains to meet your unique requirements. If you’re in the market for a new conveyor, don’t forget to shop around. CZPT Chain can help you find the perfect one.
The regular drive version consists of an ASME/ANSI roller chain wrapped around a driven sprocket. It can also be configured for variable rpm. The gear ratio between the two parts determines the reduction or increase in speed. In some cases, solution chains can be used. Roller chains are more efficient. Then, there are solutions for both cases. There are many types of conveyor chains to choose from.
Conveyor chain pitch also plays an important role in performance. The smaller the pitch of the chain, the faster it spins. On the other hand, a smaller pitch will require more teeth on the sprocket, which means more links will be engaged during the movement. This smaller articulation angle also produces smoother motion. It also reduces vibration. Therefore, CZPT Chains can be trusted for a long time.

roller chain

The performance of a drive chain depends on how well it is maintained and lubricated. Careful attention to detail is required when selecting a roller chain, which is one of the most important components in a drive chain. Its proper lubrication and assembly will significantly affect its wear life. Here are some important tips to follow when buying a roller chain:
The size of the drive chain should be selected according to the sprockets used. The large sprocket should have at least 25 teeth, and the small sprocket should have fewer teeth. The pitch of a drive chain is the contact angle between the chain and the sprocket. The smaller the sprocket, the smaller the contact angle of the two parts. Larger sprockets are better, but smaller sprockets must never have fewer teeth.
When purchasing a roller chain, be sure to consider the maximum speed of the small sprocket. This will determine how much lubrication you need. Different lubrication systems have different requirements. Manual lubrication limits how many feet per minute the drive chain can run, while oil bath lubrication can get you up to 1100 ft/min. The only way to maximize drive chain speed is to purchase a pump lubrication system.
Once you have the right length, you can determine if you need a new one. To do this you have to move the axis to measure the length. Once the length is determined, the drive chain should be removed from the sprocket and measured using the ANSI specified measuring load. You should also follow safety guidelines when measuring your chain. If you want to maximize the life of your drive chain, be sure to follow these tips.
Another important consideration is the type of environment you operate in. For applications that need to avoid rubbing steel rails, it is best to use a roller chain that can withstand a clean indoor environment. Although roller chains are generally more durable, they must be stored properly to avoid corrosion. If you care about the environment, consider opting for double chain. Its durability and low maintenance costs will make it a valuable investment in your business.

closed pivot

Closed-end pivot drive chains are used in a variety of applications. They are known for their durability, high strength, and long life. They are available in a variety of grades, including grade 400, grade 600, and grade 800 pivots, which can withstand the high forces required for certain applications. Enclosed pivot chains can be used to lift, pull, convey and transfer heavy loads.
Class 400 closed-end pivot chain features one-piece cast offset link construction. Steel pins connect each link and are prevented from rotating by head stops. This design allows the pin to connect inside the barrel without breaking. This type of chain is the most commonly used and has the highest durability. In addition to being extremely durable, it offers long-lasting performance and smooth operation.
Another closed-end pivot conveyor chain drive is called a power drive chain. These chains consist of barrels and links used to transmit rotation from one shaft to another. The barrels of the closed-end pivot chains are made of steel, which allows them to run easily on the sprockets. Block drive chains are used for low-speed applications, but they can be noisy when the chain is in contact with the sprockets.
The enclosed pivot drive chain has rollers on both ends to minimize wear. These chains are usually made of steel and can be used in areas where high-speed power transmission is required. They are also available in heavy-duty versions. Unlike other types of chains, steel pivot chains are designed for a variety of applications. They are suitable for heavy-duty applications and their open barrel design allows for minimal contact with the pins in the barrel and the root of the sprocket.
chain

Linear chain

CZPT is an important part of linear drive technology. This type of chain is capable of delivering real power in tight spaces. Typically, loads are moved by pulling or pushing. CZPT can perform both types of movements. They can push and pull additional loads. This type of chain can also be wound and stored in the magazine. It is a popular choice for small machine tools and many other uses.
Unlike traditional mechanical chains, CZPT uses a push-pull strategy to move heavy objects. It is a rigid locking design that prevents kinking and allows the chain to transmit force without bending. The CZPT is an excellent choice for moving large loads and is particularly versatile in power transmission. However, CZPT is more expensive than traditional drive chain options.
The service life of a linear chain depends on its design, material type and size. You may want to buy a good quality chain, but it’s not necessary in all cases. While superior quality can extend the life of the chain, it may not be necessary for low-speed drives or very light shock loads. If you’re not dealing with high-velocity shock loads, you probably don’t need features like oil reservoirs or bushing grooves.
The size of the drive sprocket can have a major impact on the overall life of the linear chain. It determines how fast the chain can go and how much horsepower it can produce. An 11-tooth chain will hit about half its rated speed, but only about 30 percent of its rated horsepower. You can extend the life of your linear chain by choosing a drive sprocket with a higher number of teeth. It is best to choose a drive sprocket with a high number of teeth, but make sure the number of teeth is even. This will ensure that your chain wear is evenly distributed.
