Title: Life of concentrated contacts in the mixed-ehd and boundary-film regimes. Final report

Abstract

This analytical and experimental program investigates the influence of surface finish, material and lubricant on rolling contact bearings operating in the low or marginal lubricant film regime. The investigation includes failure analysis of field failures encountered with Helicopter mast support and planetary gear transmission bearings, computer analysis of the above two bearing applications using SKF computer programs SHABERTH and PLANETSYS and testing of specimens made of M50 and 9310 steel using a geared roller tester at NAPC.
