1. What is a roller chain?

A roller chain (also known as a drive chain) is a part of a power transmission system. It is used to transmit power between a roller and one or multiple sprockets, with the teeth of the sprocket engaging with the links of the chain. As the sprocket rotates, the chain will pull and deliver mechanical force into the power transmission system, generating power and contributing to the operation of the system

2. Construction of a roller chain

The construction of a roller chain includes the following main parts:

Plate

The connecting point between the chains to form a transmission chain. The plate is made of steel or an alloy that can withstand tension on the chain. On each chain, there are two main types of plates: inner link plates and outer link plates

Pin

The component that holds the chain links together. They are usually made of high-strength steel and are inserted into the chain links by being pushed through the holes in the links. Chain pins help create a rotational movement of the sprocket during the power transmission process. Depending on the type of chain, chain pins can be designed with different sizes and shapes to suit the specific requirements of the power transmission system

Bush

The component used to protect the chain pins as they move through the chain links. Bushes help reduce friction and ensure that the chain pins do not come loose from the chain links during the power transmission process

Roller

The roller is an important component of the power transmission chain. It is mounted between the chain pins and moves on the inner surfaces of the chain links to transmit power and bear loads. Rollers are typically made of steel and are precisely machined to ensure accurate dimensions and high durability. Different types of rollers may be used for different applications depending on the hardness, weight, and speed of the power transmission system. (RS25 and RS35 chains do not have rollers)

Chain Accessories

• Connecting Link (CL)

The CL, also known as a connecting link or a chain link, is an important component of the power transmission chain. Its function is to connect two sections of chain or two ends of a chain together. It allows the chain to be shortened or lengthened as needed during installation or maintenance. Multiple connecting links can be used on a single chain depending on the user’s requirements.

There are two types of connecting links: slip fit connecting links and cotter pin connecting links. Roller chain structure of power transmission chain

• Offset Link (OL)

Offset Link (OL) is an accessory of the power transmission chain used to increase the length of the chain or make the chain symmetrical. Essentially, OL consists of two parts: a part with grooves to hold the chain rollers and a part that connects two chains together. Roller chain structure of power transmission chain

3. CHow to assemble a chain

Roller chain is an important component of many mechanical systems used in various applications. With the development of technology, modern roller chains have been designed to meet the specific requirements of power transmission systems, while improving their performance and durability
