摘　　要：面齿轮传动的动态特性将直接影响到传动系统的可靠性。本文基于集中参数理论,建立了正交面齿轮传动系统的多自由度弯曲-扭转-轴向移动-扭摆耦合振动的三维空间动力学模型。采用有限元方法计算了点接触的面齿轮传动系统的轮齿啮合刚度。模型中考虑了轴承的弹性变形和误差激励,采用W ilson-θ法,对面齿轮传动系统的动态响应进行了数字仿真分析,得到了系统的动态响应。计算结果表明,面齿轮传动系统有周期性参数激励的共有特性,振动特性较复杂,传动误差对动载荷系数影响较大。The dynamic characteristics of the face gear drive influence the reliability of the transmission system directly. Based on the theory of concentrated parameters, a three-dimensional dynamic model with multiple degrees of freedom for coupling vibration of a face gear transmission system is developed, which includes the flexional, torsional, axial and rotational motions. The mesh stiffness of the face gear transmission system is calculated by finite element method. The model takes into consideration the elastic deformation of the bearings and the transmission error. Using the Wilson-θ numerical method, the dynamic responses of the face gear transmission system are obtained. The calculation results show that the face gear transmission system has the same characteristics of periodic parameter excitation, and the transmission error has great effect on the dynamic load factor.
