| Abstract: | This paper discusses the FEM calculation of the bulk temperature and thermal deflection of gear tooth under stable loading and heat equilibrium. A computer solfware has been worked out to calculate the tooth bulk temperature and thermal deflection. The problems of calculating head-exchange coefficient and frictional heat as well as their effects on the distribution of heat-input are also discussed. Finally, the improvement of tooth profile modification, on the basis of the values of the thermal deflection calculated, is proved by using an experiment on the CL-100 type gear test machine. |
