摘要

Surface integrity is an important indicator that affects the meshing performance of face gears. How to achieve pre control of surface integrity is a hot research topic today. Based on the structural characteristics of the high load-bearing tooth surface of the face gear and the method of grinding the face gear with a large disc grinding wheel, this article establishes an analysis model for the grinding roughness of the face gear tooth surface. Furthermore, the mathematical model of the grinding force of the face gear is studied. According to the theory of triangular heat sources, a mathematical model of the grinding heat of the face gear is established. The stress and strain process of the tooth surface during the generative grinding process of the face gear is studied, and a mathematical model for calculating the stress and strain of the grinding tooth surface of the face gear is established. By designing a series of parameters to obtain a dataset of residual stress on the tooth surface, a response surface model driven by basic data was established. The Particle Swarm Optimization (PSO) was achieved with the optimization objectives of grinding wheel swing speed and single grinding depth, which improved grinding efficiency while ensuring surface grinding quality.
