英文摘要：

The relative sliding velocity, the coefficient of friction and frictional heat flux between contact tooth flanks are calculated. The 3-D finite element model of gear tooth of spiral bevel gear is built. Base on the finite element model, the steady bulk temperature of spiral bevel gear is calculated, and the sensitivity of the steady bulk temperature to speed, load and oil inlet temperature are analyzed. The results are significant in improving the transmission properties and lubrication conditions of spiral bevel gear.
