Abstract

Investigations into fatigue failure of the cam rings of hydraulic motors revealed a characteristic ripple superimposed on the surface profile. It was also found that the incidence of failure coincided with sites having high humidity.

This paper shows how reduced fatigue life under these conditions may be estimated.
