ABSTRACT:
A drive sprocket assembly for driving an endless chain assembly for propelling a vehicle includes a housing, which is mountable to the power drive system of the vehicle, and a plurality of replaceable teeth structures which are secured to the housing. The housing includes a hub portion having a cushion band and spaced apart parallel flanges. Each tooth structure is in contact with the hub and is secured to the flanges by a plurality of retaining pins. Each tooth structure is resiliently isolated from the hub by the cushion band and from adjoining teeth structures by non-metallic pads. Conventional drive sprocket assemblies utilize a one-piece toothed sprocket, or sprocket segments having several teeth, bolted to a support member. These prior sprocket assemblies produce considerable noise from impacting of the sprocket teeth with an endless chain assembly. The subject sprocket assembly produces low levels of noise by utilizing individually replaceable teeth structures which are resiliently isolated from the support housing and from adjoining teeth structures.
