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 benefits of using stainless steel mechanical chains?

Stainless steel mechanical chains offer several advantages in various applications where corrosion resistance and durability are essential. Here are some of the key benefits:

  • Corrosion resistance: Stainless steel chains are highly resistant to corrosion, making them ideal for applications exposed to moisture, chemicals, or harsh environments. They can withstand rust, oxidation, and chemical reactions better than standard steel chains, ensuring longer service life and reliable performance.
  • High strength: Stainless steel chains retain their strength even in challenging conditions. They have excellent tensile strength, allowing them to withstand heavy loads and high-stress environments without compromising performance or safety.
  • Hygienic properties: Stainless steel chains are easy to clean and maintain, making them suitable for industries with strict hygiene requirements, such as food processing, pharmaceuticals, and medical devices. The smooth surface of stainless steel prevents the accumulation of contaminants and facilitates thorough cleaning, reducing the risk of contamination.
  • Temperature resistance: Stainless steel chains exhibit good resistance to high and low temperatures, making them suitable for applications that involve extreme temperature variations. They can maintain their mechanical properties and performance even in environments with elevated or sub-zero temperatures.
  • Longevity and durability: Stainless steel chains have a longer lifespan compared to standard steel chains due to their corrosion resistance and robust construction. They require less frequent replacement, resulting in cost savings and reduced downtime.
  • Versatility: Stainless steel chains are available in various configurations and sizes to accommodate different application requirements. They can be found in a wide range of industries, including food processing, chemical processing, marine, pharmaceuticals, and more.
  • Aesthetic appeal: Stainless steel chains have a visually appealing appearance and are often chosen for applications where aesthetics are important, such as architectural designs or decorative installations.

Overall, the use of stainless steel mechanical chains provides enhanced performance, longevity, and resistance to corrosion, making them a reliable choice in demanding environments where traditional chains may not withstand the conditions. It is important to select the appropriate grade of stainless steel based on the specific application requirements to fully leverage these benefits.

What are the noise levels associated with mechanical chains?

When it comes to noise levels, mechanical chains can generate varying amounts of noise depending on several factors. Here are some detailed considerations:

  • Chain Type: Different chain types produce different noise levels. For example, roller chains generally generate less noise compared to some other types, such as leaf chains or silent chains.
  • Lubrication: Proper lubrication of the chain can help reduce noise by minimizing metal-to-metal contact and reducing friction. Insufficient or improper lubrication can lead to increased noise levels.
  • Tension: Incorrect chain tension can result in excessive noise. It is important to maintain proper tension to prevent the chain from slapping against the sprockets or other components.
  • Wear and Maintenance: A worn-out or poorly maintained chain can produce more noise due to increased friction and potential misalignment. Regular inspection and maintenance can help mitigate noise issues.
  • Operating Conditions: Factors such as speed, load, and environmental conditions can affect noise levels. Higher speeds and heavier loads can contribute to increased noise, while operating in a damp or dusty environment may amplify noise.

It is important to note that excessive noise from a mechanical chain can be indicative of underlying issues such as misalignment, insufficient lubrication, or worn components. Regular inspection and maintenance can help identify and address such issues, reducing noise levels and ensuring proper chain performance.

If noise reduction is a critical requirement for your application, there are additional measures that can be taken, such as using noise-dampening materials or employing noise reduction techniques at the system level. Consulting with experts in chain design and application can provide further guidance on noise mitigation strategies.
