ABSTRACT:
A cushion ring sprocket assembly includes a sprocket body with a plurality of teeth arranged in a row. The sprocket body includes first and second opposite axial tooth faces and first and second hubs that extend axially outward relative to the first and second tooth faces. First and second sets of cushion rings are captured on said first and second hubs, respectively. The first set of cushion rings includes at least a first inner cushion ring eccentrically located on the first hub and a first outer cushion ring eccentrically located on the first inner cushion ring. The second set of cushion rings includes at least a second inner cushion ring eccentrically located on the second hub and a second outer cushion ring eccentrically located on the second inner cushion ring. The first and second outer cushion rings are adapted to be contacted and deflected by link plates of an associated chain, so that the first and second outer cushion rings contact and deflect the respective first and second inner cushion rings. First and second retaining devices are connected to the first and second hubs to capture the first and second ring sets on the first and second hubs, respectively.
