摘要/Abstract

摘要： 行星轮安装孔周向位置误差是行星轮系制造加工过程中的一种常见误差，该误差会导致行星轮系轮齿间的啮合线长度和啮合相位发生变化，使行星轮系出现异常振动、噪声和载荷分布不均等问题，加速行星轮系轮齿的失效。针对行星轮安装孔周向位置误差激励机理不明问题，提出一种包含行星轮安装孔周向位置误差的行星轮系动力学建模方法。利用该方法推导行星轮安装孔周向位置误差与行星轮系轮齿啮合线位置、压力角和位置角之间的映射关系，及其对轮齿接触线长度和啮合相位影响特性，获得行星轮安装孔周向位置误差影响下的行星轮系动态响应。仿真结果表明：行星轮安装孔周向位置误差直接导致行星轮系齿轮刚度相位和幅值发生变化，行星轮系均载特性变差，动态传递误差和振动位移变大，且振动位移出现明显的调制线性。通过行星轮安装孔周向位置误差模拟实验验证了所提理论方法和计算结果的正确性。

Abstract: The circumferential position error of planet wheel mounting hole is a common error in the manufacturing process of planetary gear train, which may directly change the gear contact length and meshing phase of the meshing tooth pair in planetary gear train. The abnormal vibration and noise are induced by the hole circumferential positon error as well as the poor load sharing between planet gears, which accelerate the failure of planetary gear teeth. A new planetary gear train dynamic model considering hole circumferential positon error is proposed for the unclear exciting mechanisms of hole circumferential position error. In the proposed model, the relationships among contact line location, pressure angle, location angle and hole circumferential position error are studied, the contact line length fluctuation and meshing phase are discussed, and finally the dynamic responses of planetary gear train in the present of hole circumferential position error are obtained. The simulated results show that the hole circumferential position error directly leads to the phase and amplitude change of gear meshing stiffness; the load sharing characteristics,vibration displacement and dynamic transmission error of planetary gear train become worse, and an obvious modulation phenomenon has been found in the the vibration displacement. Finally, a carrier frame hole circumferential position error experiment is conducted to validate the correctness and effectiveness of the proposed method. Key
