Abstract:
Based on the principle of conjugate curve surface and the theory of hydrodynamic lubrication, the similar spherical spiral surface, which has the best lubrication effect, was obtained in the paper. Experiment show, this kind of frictional surface is lower 15% at power loss, and it is higher 13% at service life than the traditional frictional surface of piston ring, (such as barrel, stepped, cuneiform, rectangle and so on).
