Bushing and toothed wheel assembly with preferred rotation

摘要

An assembly (10) of a tapered bushing (14) and a toothed wheel (12), having a preferred direction of rotation. The assembly (10) having on each face (22, 24) a hole or set of holes H1, H2 containing surfaces which interact with a threaded rod (26) for mating and/or separating of the assembly (10) form either face (22, 24). In a preferred embodiment of the invention, the assembly (10) will have two mating holes and one separation hole on each face (22, 24) of the assembly (10). This assembly (10) allows ease of mating and/or separating the assembly when access is limited to only one face of the assembly.
