Understanding the Development and Components of a Roller Chain

The , an essential component in various mechanical systems, has a specific structure. Each component of a roller has a crucial role to play, developed to suit its respective functions. This article takes a closer look at these components and their significance.

Pins in Roller Chains

Pins in a roller chain bear all the load acting on the chain, including inner and outer plates. When the chain engages with a , the pins slide as bearings. Therefore, they need to possess substantial shearing strength, bending power, and most importantly, wear resistance.

Role of Bushings

Bushings shield the pins from the shock received via rollers when the chain engages with a sprocket. They also function as bearings in conjunction with the pins. Hence, they need to possess high shock fatigue strength and wear resistance.

Functionality of Rollers

Rollers in a roller chain smoothens the chain's bending when it engages with a sprocket, thereby shielding the chain from sprocket shock. They need to possess high shock fatigue strength, collapse strength, and wear resistance.

Importance of Plates

Plates in a roller chain are subject to repeated tension and sometimes a significant shock. As such, their requirements are high tensile strength, shock resistance, and fatigue strength.

Connecting Links in Roller Chains

There are four types of connecting links available (R, F, C and H). An R connecting link (RJ) has the connecting pins clearance-fitted with the connecting plate, while an F connecting link (FJ) is interference-fitted.

A C connecting link (CJ) has the connecting pins clearance-fitted with the connecting plate, while an H connecting link (HJ) is interference-fitted. In a conventional spring pin type of connecting link, the connecting pins are interference-fitted with the connecting plates.

Offset Links

An offset link is used to alter the length of a chain by a single pitch. As the “connecting link” and “offset link” have less strength than the base chain, it's advisable to consult with us when using them under conditions exceeding their maximum kilowatt ratings.

Clearance and Interference Fit

In a clearance fit, a space is always formed between the pin and the hole once assembled, generally used in standard connecting links. An interference fit occurs when the pin and the hole are assembled, adopted in base chains and H connecting links. However, in H connecting links, the interference is smaller than that in the chain body.
