Abstract
The temperature and residual stress in form grinding have a great influence on the quality of cycloidal gear. In this paper, with the help of finite element analysis software, the transient temperature field and transient stress-strain field of tooth surface are simulated and analyzed respectively. The results show that the node stress and strain in the grinding area are greater than those in the ground area and the area to be ground, and the stress around the tooth root is greater than that around the tooth top; The tooth surface temperature under wet grinding condition is lower than that under dry grinding condition. After cooling in the grinding area, the equivalent stress on the tooth surface gradually changes from compressive stress to tensile stress, and finally forms the surface residual stress; through the reasonable selection of grinding process parameters, the residual stress on the gear surface can be reduced. The research results have certain guiding significance for practical grinding.
