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.

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

Width (inches)

12 48 41 14
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.

bush chain

Can a bush chain be used in automotive manufacturing?

Yes, bush chains are commonly used in various applications within the automotive manufacturing industry. They play a vital role in transmitting power and motion in automotive assembly lines, conveying systems, and other mechanical processes. Here are some specific areas where bush chains are used in automotive manufacturing:

1. Conveyor Systems: Bush chains are employed in conveyor systems for transporting automotive components and parts during the manufacturing process. They provide reliable and efficient movement of materials along the production line, ensuring smooth and continuous operation.

2. Power Transmission: Bush chains are used to transmit power within automotive machinery and equipment. They transfer rotational motion from the motor to different mechanical components, such as camshafts, crankshafts, timing systems, and drive systems.

3. Engine Components: Bush chains are utilized in engine applications, such as timing chains. These chains ensure proper synchronization between the camshaft and crankshaft, enabling precise valve timing and optimal engine performance.

4. Suspension Systems: Bush chains are utilized in suspension systems to connect various components, such as control arms, sway bars, and stabilizers. They help to maintain stability, absorb shocks, and provide smooth movement of the suspension system.

5. Steering Systems: Bush chains can be found in the steering systems of vehicles, particularly in rack and pinion steering systems. They assist in translating the rotational motion of the steering wheel into linear motion, allowing for controlled steering and maneuverability.

6. Transfer Case: In four-wheel-drive and all-wheel-drive vehicles, bush chains are used in the transfer case to distribute power to the front and rear axles. They ensure proper power distribution and enable seamless transitions between different drive modes.

7. Door Systems: Bush chains are utilized in power-operated door systems, providing smooth and reliable movement of doors and windows. They contribute to the convenience and functionality of automotive doors, ensuring precise opening and closing actions.

Can a bush chain be repaired or does it need to be replaced entirely?

When a bush chain is damaged or worn out, the extent of the damage will determine whether it can be repaired or needs to be replaced entirely. Here are the considerations:

1. Minor Damage: In some cases, minor damage to a bush chain can be repaired. This includes issues such as a few broken or worn-out bushings or pins. These components can be replaced individually without replacing the entire chain.

2. Extensive Damage: If the bush chain has extensive damage, such as multiple broken links, severe wear on multiple components, or damaged sprockets, it may be more cost-effective and efficient to replace the entire chain. Repairing such extensive damage can be time-consuming and may not guarantee the chain’s optimal performance.

3. Chain Length: The length of the chain also plays a role in determining whether it can be repaired. If the damaged section is localized and doesn’t affect the overall length significantly, it may be possible to repair or replace only the affected portion.

4. Age and Condition: The age and overall condition of the bush chain should also be considered. If the chain is already worn out, has undergone multiple repairs, or is nearing the end of its service life, it is generally recommended to replace it entirely to ensure reliable operation.

5. Cost Considerations: Finally, the cost of repair versus replacement should be evaluated. In some cases, the cost of repairs, including labor and replacement parts, may exceed the cost of a new chain. In such instances, it is more economical to replace the chain.

Ultimately, the decision to repair or replace a bush chain depends on the extent of the damage, the chain’s overall condition, and cost considerations. It is advisable to consult with a qualified professional or the chain manufacturer for an accurate assessment and recommendation.

bush chain

How does a bush chain differ from other types of chains?

A bush chain, also known as a bush roller chain or bushing chain, differs from other types of chains in its construction and design. Here are the key ways in which a bush chain differs:

1. Bushing Design: The main distinguishing feature of a bush chain is the presence of bushings or sleeves between the inner and outer links. These bushings serve as bearings that reduce friction and wear between the chain components, resulting in smoother operation and increased chain life.

2. Simplex, Duplex, and Triplex Configurations: Bush chains are available in different configurations, including simplex, duplex, and triplex. These configurations refer to the number of strands of chain running parallel to each other. This allows for increased load capacity and higher torque transmission in the chain system.

3. Link Plate Design: The link plates in a bush chain are typically thicker and heavier compared to other types of chains. This design provides enhanced strength and durability, allowing the chain to withstand heavy loads and resist elongation under tension.

4. Precision Bushing Fit: The bushings in a bush chain have a precise fit with the pins, which ensures proper alignment and smooth rotation. This reduces friction, minimizes wear, and improves the overall efficiency of the chain system.

5. Lubrication Requirements: Bush chains usually require regular lubrication to maintain optimal performance and reduce friction between the components. Lubrication helps prevent wear and corrosion, ensuring the longevity of the chain.

6. Wide Range of Applications: Bush chains are versatile and find applications in various industrial settings, including machinery, automotive systems, agriculture, material handling, mining, and more. Their robust construction and ability to handle high loads make them suitable for demanding applications.

Overall, the inclusion of bushings, the configuration options, and the design characteristics of bush chains distinguish them from other types of chains. Their unique features make them ideal for applications that require durability, high load capacity, and reduced friction for reliable power transmission.
