Abstract: Mathematical model of the steady temperature field is established by combined research of heat transfer, tribology and meshing theory. Heat transfer coefficient and density of heat flow rate withdraw from the friction on the gear surface are analyzed. By using FEM the relevant program is compiled based on the geometric and kinetic characteristics of worm gear surface. It shows that the calculated result and experiment result are basically agreed with each other. The research results give support to the research of scuffing failure and EHL.
