摘要

The thermal balance state of high-speed and heavy-load gear transmissionsystem has an important influence on the performance and failure of geartransmission and the design of gear lubrication system. Excessive surfacetemperature of gear teeth is the main cause of gluing failure of gear contactsurface. To investigate the gear heat distribution in meshing processand discuss the effect of thermal conduction on heat distribution,a finiteelement model of spur gear is presented in the paper which can representgeneral involute spur gears. And a simulation approach is use to calculategear heat distribution in meshing process. By comparing with theoreticalcalculation, the correctness of the simulation method is verified, and theheat distribution of spur gear under the condition of heat conduction isfurther analyzed. The difference between the calculation results with heatconduction and without heat conduction is compared. The research hascertain reference significance for dry gear hobbing and the same type ofthermal-structural coupling analysis.
