The Influence of Slide–Roll Ratio on the Extent of Micropitting Damage in Rolling–Sliding Contacts Pertinent to Gear Applications

This paper provides new understanding of the tribological mechanisms that drive the occurrence of micropitting damage. EHD film thickness measurements were clearly able to show that increased micropitting damage resulting from higher slide roll ratios was not caused by a significant reduction if lubricant film thickness, questioning many of the assumptions currently being made to assess and predict micropitting damage in gears.
