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

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.

What are the best practices for storing and handling mechanical chains?

Proper storage and handling of mechanical chains are essential to maintain their performance and prolong their lifespan. Here are some best practices to follow:

  • Clean and dry storage: Store mechanical chains in a clean and dry environment to prevent the accumulation of dirt, moisture, or contaminants that can affect their performance.
  • Avoid extreme temperatures: Avoid storing chains in areas with extreme temperatures, as high temperatures can degrade the lubrication and material properties, while low temperatures can make the chains more brittle.
  • Prevent contact with chemicals: Keep mechanical chains away from chemicals or corrosive substances that can damage the chain’s surface or corrosion-resistant coatings.
  • Use appropriate containers: Store chains in suitable containers or packaging to protect them from external elements and prevent tangling or entanglement.
  • Proper handling techniques: When handling chains, avoid dropping them or subjecting them to impact or excessive bending, as it can cause deformation or damage to the chain links.
  • Inspect before use: Before using a stored chain, inspect it for any signs of damage, such as bent or worn links, excessive corrosion, or elongation. If any issues are found, replace the chain or consult a professional for evaluation.
  • Follow manufacturer guidelines: Always refer to the manufacturer’s guidelines for specific storage and handling recommendations for the particular type of mechanical chain you are using.

By following these best practices, you can ensure that your stored mechanical chains remain in good condition and ready for use when needed. Regular maintenance, including proper lubrication and periodic inspections, should also be carried out to keep the chains in optimal working condition.

How does a mechanical chain compare to other types of power transmission systems?

When comparing mechanical chains to other types of power transmission systems, it’s important to consider factors such as efficiency, load capacity, speed, cost, maintenance requirements, and application suitability. Here is a detailed comparison:

Aspect Mechanical Chain Comparison
Efficiency A properly lubricated mechanical chain can offer high efficiency, typically ranging from 90-98%. However, efficiency can decrease with wear and improper maintenance. Efficient power transfer, but can be affected by wear and maintenance.
Load Capacity Mechanical chains are known for their high load capacity and ability to handle heavy loads and high torque requirements. Excellent load-carrying capabilities.
Speed Mechanical chains can operate at high speeds, but their performance may be limited compared to other systems like gears or belts in certain high-speed applications. Suitable for a wide range of speeds but may have limitations in very high-speed applications.
Cost Mechanical chains are generally cost-effective compared to some other power transmission systems, especially for heavy-duty applications. Relatively cost-effective.
Maintenance Mechanical chains require regular lubrication and periodic maintenance to ensure optimal performance and longevity. They may also require tension adjustment and occasional replacement due to wear. Moderate maintenance requirements.
Application Suitability Mechanical chains are widely used in various industries and applications, including automotive, industrial machinery, agricultural equipment, and more. They are suitable for transmitting power in straight or slightly curved paths. Versatile and suitable for a wide range of applications.

In summary, mechanical chains offer high load capacity, efficiency, and versatility, making them suitable for many industrial applications. However, they require regular maintenance and may have limitations in extremely high-speed applications. The choice between mechanical chains and other power transmission systems depends on specific application requirements, such as load capacity, speed, cost, and environmental conditions.

It is always recommended to consult with industry experts or engineers to determine the most suitable power transmission system for a particular application based on its specific requirements.

What are the main components of a mechanical chain?

A mechanical chain consists of several essential components that work together to transmit power and enable motion. Here are the main components of a mechanical chain:

  • Inner and Outer Plates: The inner and outer plates are flat metal plates that form the sides of the chain. They provide structural integrity and support the load-carrying rollers or links.
  • Pins: Pins are cylindrical metal rods that connect the inner and outer plates. They act as pivot points and allow the chain to flex and articulate as it moves around the sprockets.
  • Rollers or Links: Rollers or links are cylindrical components that sit between the inner and outer plates. In roller chains, they have a barrel shape and rotate on the pins, while in link chains, they are flat plates connected by pins.
  • Bushings: Bushings are cylindrical metal sleeves that fit inside the rollers or links. They reduce friction between the pins and the rollers/links, allowing smooth rotation.
  • Sprockets: Sprockets are toothed wheels with grooves or teeth that engage with the rollers or links of the chain. They transmit power and control the movement of the chain. Sprockets are typically mounted on shafts or spindles.
  • Tensioning and Guide Devices: Tensioning and guide devices are used to maintain proper tension in the chain and guide its path along the sprockets. These devices include tensioners, idler sprockets, guide rails, and chain guides.
  • Lubrication System: Many mechanical chains require lubrication to reduce friction and wear. Lubricants are applied to the chain to ensure smooth operation and extend its service life. Some chains may have self-lubricating properties or use specialized lubrication systems.
  • Connecting Links: Connecting links, also known as master links, are used to join the ends of the chain together. They typically have removable pins or clips for easy assembly and disassembly.

These components work together to form a complete mechanical chain, enabling it to transmit power, provide flexibility, and control the motion of machinery or equipment. The specific design and arrangement of these components may vary depending on the type of chain and its intended application.
