Abstract：In order to analyze the influence of the related factors on the body temperature of high-speed gear in the meshing process,taking the standard involute gear as study object,based on the finite element analysis of temperature field and using the control variable method,the influence law of related factors on gear temperature is analyzed quantificationally.The results show that,the body temperature on tooth surface increase as rotation rate or torque increases,and the temperature increase amplitude decrease as rotation rate or torque increases.The temperature on tooth surface uniformly increase when tooth width increases,the change of modulus cause the changes of multiple factors and temperature on tooth surface decrease and then increase as modulus decreases.When rotation rate or torque is higher,the influence of rotation rate,torque,tooth width,modulus on gear temperature become bigger.The maximal body temperature increases or decreases as air and lube oil temperature,and the change has nothing with rotation rate or torque.The influence of heat transfer coefficients of gear end and meshing surface on gear temperature is relatively small,and temperature decreases as heat transfer coefficients increase.A reference for reducing the risk of gear high-temperature failure is provided.
