Computational Procedure of Wear Resistance of Gear Transmission Teeth under Skew of the Axes of Conjugated Wheels

Abstract

This paper considers the wear process of the teeth of straight spur gear transmissions under the conditions of skew of the axes of conjugated wheels. The method for determining the magnitude of wear of tooth profiles, taking the skew angle into account, is based on the dependence of average contact pressure on the skew angle. To determine the contact pressure, the physical and mathematical model of contact interaction of cylindrical elastic bodies is used when they are skewed using the Winkler model of elastic foundation. It is established that the presence of skew angle of teeth of 0.1° increases the wear rate by 3.61 times.
