SHEAVE ASSEMBLY FOR A TIRE LIFT/CARRIER WINCH

摘要

A two-piece sheave assembly is provided for a tire lift/carrier winch. The sheave assembly includes a molded plastic, one-piece sheave component (30) that is molded to include a first sheave side plate (40, 41), an integral sheave center hub (54) with a cable-wrapping track (62) thereon and optionally an integral annular toothed driven ring gear (18) for mating with a toothed drive gear (16) of the winch. The molded plastic sheave component (30) is attached to a second sheave side plate (32), which may be metal, to form the two-piece sheave assembly. Apertures (84, 89) for the winch drive shaft and the pivotable cable end fitting (32) are integrally molded in the first sheave component.
