摘　　要：齿轮传递误差是行星齿轮系统产生附加内部动载荷的主要原因之一.为更准确描述行星齿轮系统动态特性,建立了考虑齿轮传递误差因素影响的行星齿轮动力学数学模型,定量得出了系统误差引起的行星齿轮内部激励模型.数值计算结果显示,考虑误差引起的内部激励时,太阳轮、内齿圈和行星轮的动态力峰值较理想行星系统分别提高了36.7%和28.5%.得出内部误差激励频率主要影响位移响应的高频区,位移响应的低频区是由行星架转轴频率激发的外激励频率引起;行星系统的振动速度和振动加速度主要由内部啮合频率以及他们的谐频成分激发产生,传递误差引起的内部动态激励是行星系统发生高频振动的主要原因.Transmission error is one of the main reasons for the additional internal dynamic load generated by the planetary gear system.In order to describe the dynamic characteristics of the planetary gears system more accurately,a dynamic model is established for the planetary gears,which considers the influence of the transmission error factors between the gears,and the internal excitation model which is caused by the system error is obtained in the planetary gears system.The numerical results show that the dynamic force peaks of the sun gear,the ring gear and the planet gears are increased by 36.7%and 28.5%respectively compared with the ideal planetary system when considering the internal excitation caused by the transmission error.The internal error excitation frequency mainly affects the high frequency area of the displacement response,and the low frequency region of the displacement response is caused by the external excitation frequency which is excited by the rotation frequency for the planet carrier.The vibration velocity and acceleration are mainly generated by the internal meshing frequency and their harmonic frequency components for the planetary system.Internal dynamic excitation caused by transmission errors is the main reason for high-frequency vibration of planetary systems.
