Abstract
A sprocket assembly which is either driven by a drive chain or which drives the drive chain includes a hub centered about a sprocket axis and defining a hub radially outer surface; a plurality of sprocket teeth extending radially outward from the hub; and a cushion ring assembly adjacent to the plurality of sprocket teeth and circumferentially surrounding the hub radially outer surface. The cushion ring assembly includes a cushion ring adjacent to the plurality of sprocket teeth and circumferentially surrounding the hub radially outer surface; the cushion ring being resilient and compliant. The cushion ring assembly also each includes a retention ring which is partially embedded within the cushion ring and which engages the hub radially outer surface in an interference fit, the retention ring providing axial and radial retention of the cushion ring to the hub.
