Rippling failure occurring on rollers and gears is well known as one of the phenomena resulting from plastic flow of the surface layer caused by repeated sliding-rolling contact. We previously investigated rippling failure occurring on gears and rollers by using only turbine oil as lubricant. The rippling failure which occurs due to the repeated higher contact stress is closely related to lubricant. In this paper, we considered how lubricants influence the rippling failure. In particular, the effects of additives and viscosity of lubricants were investigated in detail.
