摘要
<jats:p>Aiming at the issue on grinding burn of tooth face, the temperature field formed in helical gear form grinding was analyzed. The finite element model of the single tooth of helical gear was firstly established. Considering the nonlinear relation of the physical properties of gear material to temperature, 3D finite element simulation of transient temperature field was performed by using the rectangular moving heat source model. Finally, the temperature field distribution on tooth face was achieved. The study results show that the temperature is relative low when grinding starts, then the temperature increases rapidly, and the temperature reaches the maximum value at the end of grinding; the increase of grinding depth can result in the rise of temperature when other parameters are the constants.</jats:p>
