Camshaft working conditions and materials

作者: Release Date: 2017-02-16 Author: Click:

Cam bearings are subject to periodic shock loads. The contact stress between the cam and the tappet is very large, and the relative sliding speed is also high, so the working surface of the cam is relatively worn. In view of this situation, in addition to the higher dimensional accuracy, smaller surface roughness and sufficient rigidity, the camshaft journal and cam working surface should also have higher wear resistance and good lubrication.

Camshafts are usually forged from high-quality carbon steel or alloy steel, and can also be cast from alloy cast iron or ductile iron. The journal and cam working surface are polished after heat treatment.
