摘　　要：建立了计及轮齿时变啮合刚度、啮合阻尼、支承刚度和阻尼的齿轮系统扭转-横向振动耦合的3自由度动力学模型。用数值仿真方法,研究了重合度、支承刚度、啮合阻尼和支承阻尼对齿轮动态传递误差和动力稳定性的影响。研究结论对于高速、精密齿轮传动的动力学设计具有积极意义。A three-degree-of-freedom dynamic mode! coupled transverse-torsional motion of a geared rotor-bearing system, which includes time varying mesh stiffness, mesh damping, bearing stiffness and bearing damping, is developed. Influences of involute contact ratio, bearing stiffness, mesh damping and bearing damping on the dynamic transmission error and vibration stability of the gear system are investigated using digital simulation technique. The conclusions are helpful to dynamical design of high-speed and precision gear transmission.
