Abstract:

The nature of the contact in machine parts, and, in particular, in a cam mechanism depends on the specific pressure, the microgeometry, and the properties of the material. Plastic deformations on friction surfaces have also been noted by many authors, even in quenched steels. Formulas are derived in the paper for the wear of a cam mechanism with several different types of contact. The formulas were verified directly by experiments on operating cam mechanisms. The formulas obtained support the basic conclusion of the paper that the normal wear of a cam profile is proportional to the loading acting on the higher kinematic pair of the cam mechanism, to a power greater than 1.5.
