Abstract Dynamic model of gear transmission system with consideration of tooth surface friction and thermal deformation was discussed. A nonlinear differential dynamic equation of involute spur gear considering temperature, tooth surface friction, backlash and time-varying mesh stiffness was built. The numerical examples were analyzed. The results show that the influence of friction coefficient and temperature on system dynamic response is related to torque fluctuation frequency. When the frequency is low, system shows the sign of periodic motion and the influence of friction and temperature is not obvious. When the frequency is high, friction and temperature have a great influence on gear transmission accuracy and motion form. System motion form changes from quasi periodic motion into chaos along with the increase in friction coefficient and temperature. And the rattle condition becomes more complex.
