Starter Motor Having Clutch with Grooved Roller Elements
Abstract:
A clutch includes an outer clutch member, an inner clutch member, and a plurality of roller members. The outer clutch member defines an opening, and the inner clutch member is at least partially positioned within the opening. The inner clutch member includes a clutch surface. The plurality of roller members is at least partially positioned within the opening between the clutch surface and the outer clutch member. The roller members define a plurality of roller surfaces separated by at least one annular groove. Each of the roller members is displaceable within the opening to position the roller surfaces into engagement with the clutch surface to lock the inner clutch member into synchronous movement with the outer clutch member in response to movement of the inner clutch member in a rotational direction.
