Abstract:
In one form, the present disclosure provides for a sprocket assembly including a sprocket wheel and a sprocket cushion. The sprocket wheel can include teeth extending radially outward from a hub. The cushion can be coupled to the hub on a first axial side of the teeth. The cushion can include an annular base and a plurality of projections. The base can be disposed about the hub and the projections can extend radially outward therefrom. Each projection can include a first axial end, second axial end, top surface, and chamfer. The first axial end can be proximal to the first axial side of the teeth. The top surface can extend axially between the first axial end and the second axial end. The chamfer can join the second axial end and the top surface such that a radial thickness of each projection decreases with increased axial distance away from the teeth.
