Abstract

The friction arising between gear tooth pairs is a main factor influencing the operational efficiency and fatigue life of gear transmissions. In this paper, a numerical analysis method is proposed for predicting friction characteristics including friction coefficient, normal forces and friction forces of involute spur gear under elastohydrodynamic lubrication (EHL) condition and different wear phases. The gear surface wear model based on widely used Archard’s formula is employed to predict the change of tooth profiles. The results show that friction forces of meshing points in double tooth-meshing zone near dedendum firstly decrease and then increase with the increase of wear depth. Friction forces of meshing points in double tooth-meshing zone near addendum firstly increase and then decrease with the increase of wear depth. Friction forces of meshing points in single tooth-meshing zone decrease slightly. This study provides a theoretical basis for the optimal design of tribological behaviour of gear for reducing the occurrence of gear failures and increasing the gear service life. Moreover, it also helps to understand the dynamic behaviour of gears under different operation phases for developing accurate condition monitoring methods.
