Tribology---the science of combatting wear. Part 7. W.A. Glaeser et al. Lubric. Engng., May 1994, 50(5), 381--384.
Elastohydrodynamic lubrication (EHL) is reviewed for rolling and sliding contacts. Applications in roller and ball bearings, gears, cams and cam-followers, and traction drives are described and illustrated. Advantages and disadvantages of EHL are discussed and the mechanism involved in the protection of metal contact zones from localized areas of very high temperature and pressure is reviewed. EHL is described as affecting bearing performance in several crucial ways. These are bearing life, friction, cage dynamics, edge stresses, and temperature. Each of these performance aspects is discussed.
