Meshing Performance Analysis of Face Gear Drive under Heavy Load with Assembly Error

针对实际应用中的重载面齿轮传动接触轨迹分析较为复杂,不仅包括初始装配误差,还有重载作用下支承系统的变形等,引入载荷当量安装调整值概念,利用解析法和有限元方法分别将重载作用下支承轴、轴承和箱体的变形转化为初始装配误差,通过推导考虑装配误差的面齿轮传动接触轨迹的方程组进行计算,并将其进行可视化处理,得到了面齿轮传动接触轨迹随着不同载荷变化的移动规律,为面齿轮传动接触轨迹的精确可控及预测提供了参考依据。

Analysis of contact path in face gear drive under heavy load is complicated in practical application including key factors such as initial assembly error and deformation of the support system. Deformation of support axis and bearings, and deformation of gearbox are transformed into the initial assembly error by introducing the concept of load equivalent assembly adjustment value. Use the analytical method and finite element method respectively. Finally, there comes out several of contact path in face gear drive under the different load by calculating the equation set on contact path with assembly error of face gear transmission, and provide reference frame for controlling contact path accurately.
