Abstract

Experiments were conducted using the gear-cam arrangement of contacts to measure the wear behavior of rollers rolling and sliding over a flat plate. This assembly was used to simulate the normal gear contacts. The effects of varying the applied load, speed of rotation and surface roughness on the friction force, oil temperature and friction coefficient and wear weight were investigated. It was found that the effect of applied load on the wear weight is more significant than that of the speed of rotation. In addition, there are no definite relationships between the friction coefficient, applied load and rotation speed. The longitudinally oriented rough surfaces caused less wear compared with the smooth surfaces, although lower temperatures were usually found on the smooth surfaces. The oil temperature increased as the sliding speed or the applied load increased.
