摘　　要：综合运用齿轮啮合学、摩擦学和传热学知识,精确计算了轮齿不同啮合位置的摩擦热流密度以及轮齿啮合面、端面的对流换热系数。利用ANSYS软件建立了直齿轮单个轮齿的有限元模型,获得了轮齿的本体温度场,分析了扭矩、转速以及润滑油输入温度等关键参数对轮齿本体温度场的影响。研究结果表明:轮齿最高温度区域分布在轮齿啮合接触面的中心部位,轮齿啮合面温度沿齿宽方向近似呈抛物线分布;轮齿的最高温度随扭矩、转速和润滑油输入温度的增加而增加;仿真值和试验值基本吻合,证明仿真分析方法可用于齿轮本体温度场的研究。With the comprehensive application of gear meshing,friction and thermal conduction,heat flux and heat transfer coeffi-cient for the contact surface and end faces in different meshing position were analyzed precisely.The finite element model of a sin-gle tooth was built up in ANSYS,and the bulk temperature field of the tooth was obtained;besides,the effect of torque,speed and oil input temperature on the bulk temperature field was also analyzed.The study results show that the highest temperature field of the tooth distributes in the center of the gear meshing position,and the bulk temperature of the contact surface is nearly in para-bolic distribution along the tooth width.The highest temperature of the tooth increases with the increase of the torque,speed and oil input temperature.The simulation results coincide with the experimental results,and the simulation methods can be used for the study on the bulk temperature field of spur gear.
