1. Three Basic Dimensions
Pitch, Roller Diameter and Inner Width are known as the “Three Basic Dimensions of Roller Chain.” When these three measurements are similar, roller chains and sprockets are dimensionally compatible.
2. Basic Parts
The plate may be the component that bears the strain agricultural Chain positioned on the chain. Generally that is a repeated loading, sometimes accompanied by shock. As a result, the plate must not only possess great static tensile strength, it must also endure to the powerful forces of load and shock.
The pin is at the mercy of shearing and bending forces transmitted by the plate. Simultaneously, it forms a load-bearing part (together with the bush) when the chain flexes during sprocket engagement. Therefore, the pin needs high tensile and shear strength, level of resistance to bending, and must have sufficient stamina against shock and wear.
The bush is at the mercy of complex forces from all parts, especially from the repetition of shock loads when the chain engages the sprocket. As a result, the bush needs incredibly high shock resistance. In addition, the bush forms a load-bearing part alongside the pin and therefore requires great wear level of resistance.
The roller is subject to impact load since it mates with the sprocket teeth during engagement of the chain with the sprocket. After engagement, the roller changes its point of contact and balance. It is held between your sprocket tooth and bush, and progresses the tooth face while getting a compression load. Therefore, it should be resistant to use and still have power against shock, fatigue and compression. (RS25 and RS35 are bush chains , nor have rollers).
Two bushes are press fit into two roller hyperlink plates and rollers are inserted to allow rotation around the outside of the bushes during operation. This is the same for solitary and for multi strand chains.
Pin Hyperlink and Intermediate Plate
The pin link consists of two pins that have been press fit into two pin hyperlink plates. In the event of multi-strand roller chain up till size 08B, an intermediate plate is added to the pin hyperlink. In case of multistrand roller chain above size 08B, two intermediate plates are added to the pin link. The intermediate plates are slip fit for regular roller chain and press fit for SUPER roller chain.
