Cam subordinate clause system and cam subordinate clause assembly

摘要

A cam follower assembly (18) for mechanically connecting a cam (10) on a camshaft to a push rod (26) assembly is disclosed. The cam follower assembly includes a cam follower link rotatably mounted to a pivot (22) at a first end (34). At a second end (36) the cam follower link has a substantially semicylindrical recess (42) having a thin axial wall (44) formed at each end of the recess. The cam follower link contacts a push rod adjacent its second end on a surface opposite the surface having the substantially semicylindrical recess. A pinless roller (24) is mounted within the substantially semicylindrical recess and is restrained from axial movement by the thin axial walls. The pinless roller is held in rolling contact with a corresponding cam by imposition by the link of restraining force directly on the cam engaging surface of the roller. The roller may include an annular groove (46) to facilitate lubrication of the cam follower assembly.
