根据啮合与成型原理,建立了弧齿锥齿轮齿面方程。采用有限元方法对弧齿锥齿轮进行了加载接触分析,获得了弧齿锥齿轮齿面10个啮合点的接触正压力、相对滑动速度以及摩擦因数。应用传热学原理,在对摩擦热源与热传导参数分析基础上,建立了弧齿锥齿轮啮合非稳态温度场有限元模型,仿真分析了齿轮干运行齿面温度场分布及其随时间变化规律。结果表明,弧齿锥齿轮干运行初始阶段,随着啮合周期的增加,齿面温度急速上升,之后上升缓慢,在温度上升的同时还出现与啮合周期相对应的波动;啮合转速增大使温度急速上升的时间延长,同时转速的增加导致更显著的温度上升。

英文摘要：

According to the meshing and forming principle,the tooth surface equation of spiral bevel gear is established. The spiral bevel gear loaded contact analysis is carried out by using finite element method,and the contact positive pressure,relative sliding speed and friction coefficient of the tooth surface 10 meshing points are obtained. By applying heat transfer theory and based on the analysis of the friction heat and the heat conduction parameters,the finite element model of the unsteady temperature field of spiral bevel gear is established,and the simulation analysis of the tooth surface temperature field distribution and its variation with time during the dry running is carried out. The results show that during the initial stage of the dry running of the spiral bevel gear,with the increasing of the meshing period,the tooth surface temperature rising rapidly,and then rising slowly,the temperature rising is accompanied by fluctuations which correspond to the meshing cycle. The increasing of the meshing speed prolongs the time that temperature rise rapidly,and it leads more significant temperature rising at the same time.
