Abstract

Gears are one of the most complicated applications of tribology with combined rolling and sliding action on the gear teeth.There is the tendency to increase the amount of power to be transmitted through the gears with the simultaneous need to decrease the size of gears.Also environmental aspects need to be taken into account in modern gear design.The typical tribological failures that gears experience are scuffing, macro-pitting and micro-pitting.In this study the effect of surface roughness, lubricant type and surface treatment on micro-pitting performance was studied by twin disc tests.The parameters studied were surface roughness, lubricant type and surface treatment.
