ABSTRACT:
A cushion ring sprocket assembly and chain drive system are designed to prevent roller-to-root radial contact. Hard contact between the chain link plates and the cushion rings, and corresponding hard contact between the cushion rings and the sprocket hubs limit radial inward movement of the chain rollers/bushings, while the root surfaces of the tooth spaces are undercut so that the rollers cannot contact the root surfaces.
