The structure of Roller Chain :

The outer chain plate and the pin shaft, the inner chain plate and the sleeve are respectively connected by an interference fit. The gap between the sleeve and pin, sleeve, and roller is matched. When the sprocket teeth are engaged with the chain, the friction between the rollers and the teeth is basically rolling friction. Sliding friction between the sleeve and roller, pin, and sleeve.

The roller link plate is usually formed in a figure-eight shape so that the strength of each part is close, and the inertia and weight during movement are reduced. Compared with belt drive, roller chain drive has a compact structure, the small load acting on the shaft, large carrying capacity, high efficiency, and an accurate average transmission ratio.
