Analysis of the wear of gear transmission

According to the basic principle of the wear, analysis of the wear instance of the gear is present in this paper. The equation of the main factors influencing the wear of the tooth profile, such as relative sliding coefficient and contact compressive stress are established. Simulation is present with numerical method, the changing laws of relative sliding coefficient and contact compressive stress are found based on the simulation curve. The wear instance of the tooth profile is analyzed on the base. The result will be used to calculate and improve the wear instance of the gear as theory basis.
