建立了中心对称式减速器齿轮传动系统横－扭耦合振动模型，利用傅氏级数形式表达系统周期性的激振力，求解了系统的动态响应，分析了系统固有频率对减速器输出端支承刚度的灵敏度特性，并实例计算分析了输出端支承刚度对齿轮动载荷系数的影响。
The transverse-torsional coupled vibration model of the center-symmetrical gear reducer gear transmission system was established. The periodic excitation force was expressed by the Fourier series. The dynamic response of the system was solved. The influence of the natural frequency of the system on the output of the reducer Stiffness sensitivity characteristics, and examples of calculation and analysis of the output stiffness of the gear bearing dynamic load factor.
