Influence of Contact Conditions on the Onset of Micropitting in Rolling-Sliding Contacts Pertinent to Gear Applications


Recently, increased sliding has been one of the factors suggested to be responsible for the onset of micropitting, with the proposed underlying mechanism being the potential reduction of film thickness through increased sliding speed. This paper attempts to shed light on the tribological conditions that may lead to the onset of micropitting in lubricated, concentrated contacts representative of those occurring between gear teeth. In particular, the effect of slide-roll-ratio, surface roughness and film thickness is studied.
