Abstract
A wheel assembly includes a cam and a cam gear mounted on a camshaft of an internal combustion engine. The cam gear is constructed of a laminated stack of flat plate members which are disposed in abutting relationship to one another to form a plurality of axially spaced and radially extending interfaces. The cam gear is press fit onto the camshaft and the frictional forces between the gear and the camshaft provide the substantially sole force for maintaining the interfaces between the plate members in abutting relationship at their radially outer ends to form integral tooth members. The cam is also constructed of a laminated stack of flat plate members and press fit onto the camshaft in substantially the same manner as the gear to form an integral cam surface. The plates which form the cam are stamped from the plates that form the gear. The camshaft includes a serrated portion on its outside surface having plurality of axially extending axially tapered teeth that cut into the inner surfaces of the cam and cam gear to secure the cam and cam gear both axially and circumferentially thereon. A method of forming the wheel assembly is also disclosed.
