Roller Chain
When it comes to chains, roller chains are probably the one that comes to mind for most people. Roller chains or sleeve roller chains are widely used for power transmission in bicycles, motorcycles and other applications in the transportation industry. They are usually made of plain carbon steel or steel alloys.
Roller chains consist of an inner plate (roller chain plate), an outer plate (pin chain plate), bushings, pins and rollers. The rollers are placed equidistantly between the chain links. These rollers engage with the sprocket teeth and transmit power through the chain. An important advantage of roller chains is that they rotate as needed when in contact with the sprocket teeth, thus reducing power loss.
In a drive chain, the roller link plates (on each side of the rollers) are taller than the rollers. This prevents the side plates from coming into contact with the sprockets during operation. In addition to this, they act as guides and prevent the roller chain from slipping.
For roller chains in conveyors, the roller diameter is relatively larger than the height of the side bars. This prevents contact between the side bars and the conveyor track and increases efficiency by eliminating translational friction. Larger rollers also reduce rotational friction.
For greater power requirements, designers can choose multi-chain roller chains. For the same load requirements, having multiple strands allows the use of low speeds and small chain pitches
