Abstract
Apparatus for accelerating the onset of wear related damage on a circumferential cam surface including a structure for supporting a camshaft including the circumferential cam surface, a plurality of rollers having respective circumferential roller surfaces, and structures supporting the rollers at respective locations adjacent the structure for supporting the camshaft for positioning the circumferential roller surfaces for circumferential rotating contact with the circumferential cam surface. The apparatus includes a mechanism operable for rotating the camshaft with the circumferential cam surface and the circumferential roller surfaces in the circumferential rotating contact. The apparatus further includes a mechanism for variably biasing the respective rollers against the camshaft during the circumferential rotating contact simulative of actual operating conditions. The apparatus has application for evaluating wear related conditions of cams, rollers and other followers used for fuel injector actuation for internal combustion engines, as well as other applications such as for operation of engine intake and exhaust valves and the like.
