摘要：
A three-dimensional FE (finite element) simulation model of the grinding temperature field was proposed by considering the coupling effects of three adjacent heat sources(tooth bottom heat source, transition arc heat source and tooth profile heat source)to calculate the grinding temperature in profile grinding of full tooth grooves. Then, the residual stresses caused by grinding were calculated by the FE method based on thermal structure coupling. The characteristics of the grinding temperature and residual stress fields were analyzed, as well as the influences of the size of the tooth root transition arcs on the grinding temperature and the residual stress distribution at the tooth root after grinding. The results show that the effects of the transition arc radius on the grinding temperature are relatively small, but the effects on the residual stress are relatively large. Compared with a tooth groove without transition arcs, the maximum residual stress after grinding is reduced by more than 20% when the radius of the transition arcs exceeds 2 mm. The measurement results are consistent with the FE simulation ones, which proves the correctness of the simulation results. © 2022, China Mechanical Engineering Magazine Office. All right reserved.
