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..

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
in eighths
ANSI standard
chain number
Width (inches)
14 28 25 18
38 38 35 316
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.

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

Can a mechanical chain be used for heavy-duty applications?

Yes, a mechanical chain can be used for heavy-duty applications. Mechanical chains are designed to withstand high loads and provide reliable power transmission in demanding industrial settings. Here are some reasons why mechanical chains are suitable for heavy-duty applications:

  • Strength and durability: Mechanical chains are made from high-strength materials such as alloy steel or stainless steel, which give them excellent tensile strength and durability to handle heavy loads.
  • Wide range of sizes and capacities: Mechanical chains are available in various sizes and configurations to accommodate different load capacities. They can be selected based on the specific requirements of the heavy-duty application.
  • Effective power transmission: Mechanical chains efficiently transfer power from the driver sprocket to the driven sprocket, ensuring reliable performance even under heavy loads.
  • Ability to handle shock loads: Mechanical chains are designed to absorb and distribute shock loads, which is crucial in heavy-duty applications where sudden impacts or changes in load can occur.
  • Options for specialized chains: There are specialized types of mechanical chains available for specific heavy-duty applications, such as roller chains for conveying heavy materials or conveyor chains for material handling systems.

When selecting a mechanical chain for heavy-duty applications, it’s important to consider factors such as the load capacity, operating conditions, lubrication requirements, and maintenance considerations. Additionally, proper installation, tensioning, and regular inspection of the chain are essential to ensure optimal performance and longevity in heavy-duty applications.

What are the alternatives to mechanical chains in certain applications?

In certain applications, mechanical chains may not be the most suitable option, and alternative power transmission systems or lifting mechanisms can be used. Here are some alternatives to mechanical chains:

  • Belts and Pulleys: Belts and pulleys provide an alternative to mechanical chains for transmitting power or motion. They are commonly used in applications where quiet operation, high-speed capabilities, and precise positioning are required. Belts are flexible and can transmit power over long distances, while pulleys provide the means to transfer power between different components.
  • Gear Systems: Gear systems use interlocking toothed wheels to transmit power or motion. They are suitable for applications that require high torque, precise control, and compact design. Gear systems are commonly used in machinery, automotive transmissions, and robotics.
  • Hydraulic Systems: Hydraulic systems use pressurized fluid to transmit power and control motion. They are commonly used in heavy-duty applications that require high force, such as construction equipment, material handling, and hydraulic presses. Hydraulic systems provide smooth operation, precise control, and the ability to transmit power over long distances.
  • Pneumatic Systems: Pneumatic systems use compressed air to transmit power and control motion. They are suitable for applications that require fast and precise actuation, such as in automation, robotics, and industrial machinery. Pneumatic systems offer lightweight and flexible operation, easy control, and resistance to environmental contaminants.
  • Electric Actuators and Motors: Electric actuators and motors convert electrical energy into mechanical motion. They are commonly used in various applications, including robotics, automation, conveyor systems, and precision positioning. Electric actuators and motors provide precise control, high efficiency, and the ability to integrate with electronic control systems.

The choice of alternative power transmission systems depends on the specific requirements of the application, such as load capacity, speed, precision, environmental conditions, and control requirements. It is essential to consider factors like power requirements, space limitations, operating conditions, and cost-effectiveness when selecting the most suitable alternative to a mechanical chain.
