【Abstract】 The instantaneous bulk temperature field the gear is very important for the study of scoring of gears. In this paper, the affect of beside gear teeth is consided and the calculation of the instantaneous bulk temperature field of the spur gear is carried out by the finite element method. The temperatures of critical point D which varies with the teeth contact times are obtained, also the flowing results are obtained: the instantaneous bulk temperature field of point D varies with tmes; the heat exchange coefficient has the very important affect to the instantaneous bulk temperature field.更多还原
