pitch chain

Can pitch chains be used in the oil and gas industry for power transmission?

Yes, pitch chains can be used in the oil and gas industry for power transmission applications. In this industry, power transmission systems are often required to operate in harsh and demanding environments, including offshore drilling platforms, refineries, and petrochemical plants.

The oil and gas industry typically requires heavy-duty equipment capable of handling high loads, operating at various speeds, and withstanding exposure to corrosive substances. Pitch chains, especially those made from stainless steel or corrosion-resistant materials, are well-suited for such challenging conditions.

These are the key reasons pitch chains are suitable for power transmission in the oil and gas industry:

  • Strength and Durability: Pitch chains are designed to handle heavy loads and provide reliable power transmission even in demanding conditions.
  • Corrosion Resistance: Chains made from stainless steel or other corrosion-resistant materials can withstand exposure to chemicals and corrosive substances commonly found in the oil and gas industry.
  • Wide Temperature Range: Some pitch chains can operate effectively across a broad temperature range, making them suitable for both high-temperature processing and sub-zero conditions, as seen in offshore drilling.
  • Adaptability: Pitch chains can be customized to fit various applications and equipment designs, allowing for flexibility in the power transmission system’s layout.
  • Reduced Maintenance: Using high-quality pitch chains and proper lubrication can help reduce maintenance requirements, which is crucial for remote or difficult-to-access locations common in the oil and gas industry.

However, when selecting pitch chains for power transmission in the oil and gas industry, it’s essential to consider the specific requirements of the application, such as load capacity, speed, environmental factors, and maintenance needs. Regular inspections, lubrication, and preventive maintenance are essential to ensure the chains’ optimal performance and extend their service life in this challenging industrial setting.

pitch chain

What are the maintenance requirements for pitch chains to ensure optimal performance?

Maintenance plays a crucial role in ensuring the optimal performance and longevity of pitch chains. Here are the key maintenance requirements:

  • Lubrication: Regular and proper lubrication is essential to reduce friction between the chain’s moving parts, minimize wear, and prevent corrosion. Use the recommended lubricant and apply it according to the manufacturer’s guidelines. The frequency of lubrication depends on the operating conditions and the type of chain.
  • Inspections: Regular visual inspections are necessary to identify any signs of wear, damage, or misalignment. Check for elongation, wear on the sprockets, and any loose or damaged components. Detecting issues early can prevent further damage and avoid costly downtime.
  • Tension Adjustment: Maintaining the correct tension in the pitch chain is crucial for smooth operation. Over-tensioning can accelerate wear, while under-tensioning can cause the chain to jump or skip teeth. Follow the manufacturer’s recommendations for tension adjustment.
  • Cleaning: Keeping the chain clean is important to prevent the buildup of dirt, debris, or contaminants that can contribute to wear and decrease performance. Regularly clean the chain and sprockets using appropriate cleaning methods.
  • Replacement of Worn Parts: As the chain operates, it will naturally experience wear. Replace any worn or damaged components, such as pins, bushings, or rollers, with genuine replacement parts from the manufacturer.
  • Environmental Considerations: Consider the operating environment of the pitch chain. In harsh or corrosive environments, additional protective measures may be required, such as surface treatments or using chains made from corrosion-resistant materials.

It is essential to follow the manufacturer’s maintenance guidelines and keep a maintenance schedule to ensure the pitch chain’s optimal performance. Regular maintenance not only extends the life of the chain but also helps prevent unexpected breakdowns and production disruptions.

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 CHINAMFG 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 CHINAMFG 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 CHINAMFG 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 CHINAMFG 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.

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):

Pitch (inches) Pitch expressed

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.

pitch chain

Can pitch chains be used in the aerospace and aviation industries?

Yes, pitch chains can be used in the aerospace and aviation industries for various applications. While they may not be as common as in other industries, pitch chains play essential roles in specific aerospace and aviation systems. Here are some areas where pitch chains find application:

  • Landing Gear Systems: Pitch chains are utilized in the landing gear systems of aircraft. They help extend and retract the landing gear during takeoff and landing operations. The chains’ robust and reliable design is well-suited to handle the forces and loads involved in these critical functions.
  • Helicopter Rotor Systems: In helicopters, pitch chains are used in the rotor systems to control the blade pitch. By adjusting the blade pitch, the pilot can control the lift and thrust of the helicopter during flight.
  • Cargo Handling Systems: Aircraft cargo doors and handling systems may also incorporate pitch chains to facilitate the movement of cargo and ensure secure and efficient loading and unloading processes.
  • Aircraft Engine Controls: Some aircraft engine controls may use pitch chains to operate various components, such as variable stator vanes or other mechanisms that require precise adjustments during flight.

When used in the aerospace and aviation industries, pitch chains must meet stringent safety and reliability standards to ensure the utmost performance and minimize the risk of failure. Manufacturers often use high-quality materials and precision manufacturing processes to produce pitch chains that can withstand the demanding conditions of aircraft operations.

It’s important to note that while pitch chains are present in certain aerospace and aviation applications, they are just one component of the overall complex systems that enable safe and efficient flight. Each aircraft manufacturer carefully designs and tests these systems to meet industry regulations and ensure the highest level of safety and performance.

How do pitch chains handle shock loads and dynamic forces in mechanical systems?

Pitch chains are designed to handle shock loads and dynamic forces in mechanical systems through their inherent strength and flexibility. They are commonly used in power transmission applications, where they transfer motion and power between rotating components.

Here’s how pitch chains handle shock loads and dynamic forces:

  • High Tensile Strength: Pitch chains are made from high-quality materials, such as alloy steel, which provides them with high tensile strength. This enables them to withstand heavy loads and sudden impacts without failure.
  • Flexible Design: The design of pitch chains allows them to flex and adjust to varying loads and forces. This flexibility helps to distribute the shock load and prevents concentrated stress on individual links.
  • Even Load Distribution: Pitch chains consist of multiple links, and the load is evenly distributed across these links. When subjected to dynamic forces, each link shares the load, reducing the strain on any single link.
  • Engagement with Sprockets: Pitch chains engage with sprockets or toothed wheels, providing a positive drive that ensures smooth motion and minimizes the effects of shock loads. The interaction between the chain and sprocket helps to absorb and dissipate the impact energy.
  • Preventing Abrupt Stops: In some applications, shock loads can occur when the machinery comes to an abrupt stop. Pitch chains can help dampen these shocks by acting as a buffer, reducing the sudden impact and preventing damage to other components.

Despite their robust design, it is essential to consider the application’s specific requirements and select the appropriate chain size and type to ensure optimal performance. Regular maintenance and proper lubrication also contribute to the longevity and reliability of pitch chains in dynamic mechanical systems.

Can pitch chains be used in the automotive assembly line for power transmission?

Yes, pitch chains can be used in the automotive assembly line for power transmission. In the automotive industry, conveyor systems are extensively used to transport car components and assemblies along the production line. Pitch chains, with their ability to handle power transmission and material handling, play a crucial role in ensuring smooth and efficient operations in the automotive assembly process.

Pitch chains are commonly used in the automotive industry for several applications:

  • Power Transmission: Pitch chains are used to transmit power from motors to various conveyor components, such as rollers or belts, enabling the movement of car components along the assembly line.
  • Material Handling: Pitch chains are used to transport car parts and assemblies between different workstations on the assembly line. They can handle various sizes and shapes of automotive components, making them suitable for a wide range of applications.

How do pitch chains handle shock loads and dynamic forces in mechanical systems?

Pitch chains are designed to handle shock loads and dynamic forces in mechanical systems through their inherent strength and flexibility. They are commonly used in power transmission applications, where they transfer motion and power between rotating components.

Here’s how pitch chains handle shock loads and dynamic forces:

  • High Tensile Strength: Pitch chains are made from high-quality materials, such as alloy steel, which provides them with high tensile strength. This enables them to withstand heavy loads and sudden impacts without failure.
  • Flexible Design: The design of pitch chains allows them to flex and adjust to varying loads and forces. This flexibility helps to distribute the shock load and prevents concentrated stress on individual links.
  • Even Load Distribution: Pitch chains consist of multiple links, and the load is evenly distributed across these links. When subjected to dynamic forces, each link shares the load, reducing the strain on any single link.
  • Engagement with Sprockets: Pitch chains engage with sprockets or toothed wheels, providing a positive drive that ensures smooth motion and minimizes the effects of shock loads. The interaction between the chain and sprocket helps to absorb and dissipate the impact energy.
  • Preventing Abrupt Stops: In some applications, shock loads can occur when the machinery comes to an abrupt stop. Pitch chains can help dampen these shocks by acting as a buffer, reducing the sudden impact and preventing damage to other components.

Despite their robust design, it is essential to consider the application’s specific requirements and select the appropriate chain size and type to ensure optimal performance. Regular maintenance and proper lubrication also contribute to the longevity and reliability of pitch chains in dynamic mechanical systems.

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).

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.

How do pitch chains perform in continuous operation and frequent starts/stops?

Pitch chains are designed to perform well in continuous operation and frequent starts/stops, making them suitable for a wide range of applications that involve repetitive motion and varying speeds. Their performance in these scenarios can be attributed to several key factors:

  • Durable Construction: Pitch chains are typically made from high-quality materials, such as carbon steel or stainless steel, which provide excellent strength and durability. This construction allows them to withstand the stresses of continuous operation and frequent starts/stops without significant wear or elongation.
  • Smooth Engagement: Pitch chains are engineered to engage with sprockets and other components smoothly. During starts and stops, the engagement process is designed to minimize shock and vibration, reducing the impact on the chain and the entire mechanical system.
  • Lubrication: Proper lubrication is essential for pitch chain performance in continuous operation. Adequate lubrication reduces friction between the chain’s components, ensuring smooth movement and preventing excessive wear and heat buildup.
  • Chain Tension: Maintaining the appropriate chain tension is crucial for continuous operation and starts/stops. Proper tension helps prevent chain slack and excessive vibration, which can lead to premature wear and reduced performance.
  • Quality Manufacturing: High-quality pitch chains are manufactured with precision and tight tolerances. This ensures consistent performance and minimizes variations that could lead to problems during continuous operation or frequent starts/stops.

Overall, pitch chains are engineered to handle the demands of continuous operation and frequent starts/stops in various industrial applications. Regular maintenance, including lubrication and tension adjustments, is essential to keep the chains operating at their best and to extend their service life.

How do pitch chains handle wear and tear in continuous operation?

Pitch chains are designed to withstand wear and tear in continuous operation, making them well-suited for demanding industrial applications. Here’s how they handle wear and tear:

  • Material Selection: Pitch chains are often made from high-quality materials, such as stainless steel or carbon steel with specialized coatings, that offer excellent durability and resistance to abrasion and fatigue.
  • Hardened Components: Many pitch chains have hardened pins, bushings, and rollers, which further enhances their wear resistance and prolongs their service life.
  • Lubrication: Proper and regular lubrication is essential for reducing friction between the chain components. Lubricants help to prevent metal-to-metal contact, minimizing wear and heat buildup.
  • Alignment and Tension: Correct alignment and tensioning of the pitch chain are crucial to distribute the load evenly and prevent excessive stress on individual chain components.
  • Maintenance: Scheduled maintenance, including inspection, cleaning, and lubrication, is vital to identify early signs of wear and address them promptly. Replacing worn-out components before they fail can prevent chain failure and costly downtime.

Continuous operation can subject pitch chains to various stresses, including tension, bending, and impact loads. However, when installed and maintained correctly, pitch chains exhibit excellent fatigue strength, which allows them to endure repeated loading cycles without significant wear or deformation.

In high-wear environments, some pitch chains may incorporate additional features such as specialized coatings, case-hardened components, or self-lubricating properties to enhance their wear resistance and reduce the need for frequent maintenance.

In summary, pitch chains handle wear and tear in continuous operation by using high-quality materials, proper lubrication, and regular maintenance. Their robust design and durability make them reliable components for powering conveyor systems and other mechanical applications in industrial settings.

Can pitch chains handle heavy loads and high-speed operations?

Yes, pitch chains are designed to handle both heavy loads and high-speed operations in various industrial applications. The suitability of a pitch chain for specific load and speed requirements depends on its construction, material, and design considerations.

Heavy Load Handling: Pitch chains are available in a range of sizes and configurations to accommodate different load capacities. They are commonly used in industries such as manufacturing, construction, agriculture, and mining, where heavy materials or equipment need to be transported or lifted.

For heavy load applications, it is essential to select a pitch chain with adequate tensile strength, as well as consider factors such as the number of strands and the arrangement of the chain to ensure it can handle the required load without deformation or failure.

High-Speed Operations: Pitch chains can also operate at high speeds in certain applications. The design of the chain, including the shape and size of its components, plays a crucial role in its ability to maintain smooth motion at higher speeds.

When using pitch chains in high-speed applications, factors like lubrication, alignment, and tension must be carefully managed to reduce friction and wear, ensuring the chain’s longevity and efficient performance.

It is essential to consult the manufacturer’s specifications and guidelines to determine the maximum load capacity and speed ratings for a particular pitch chain model. Regular maintenance and proper lubrication are crucial to keeping the chain in optimal condition, especially when handling heavy loads or operating at high speeds.

In summary, pitch chains are versatile and can handle heavy loads and high-speed operations, making them valuable components in a wide range of industrial machinery and mechanical power transmission systems.
