摘　　要：【目的】为探究安装误差和齿面摩擦共同作用下直齿轮副啮合和动力学演化规律,采用直齿轮副几何关系分析与能量法相结合的方法,研究了安装误差和齿面摩擦对直齿轮副啮合的影响。【方法】基于集中质量法建立了直齿圆柱齿轮副6自由度弯扭耦合振动模型,通过龙格-库塔法求解获得了表征系统啮合行为及动力学响应的数值解。【结果】分析结果表明,直齿轮副啮合刚度幅值随齿面摩擦因数的增加而降低。同时仿真结果表明,适当地调整直齿轮副安装情况和合理的齿面摩擦因数,可以改善直齿轮副传动精度和振动情况。结果可为开展系统误差影响下直齿轮传动系统的动力学研究提供参考。[Objective]To explore the meshing and dynamic evolution of spur gear pairs under the combined influence of assembly errors and tooth surface friction,a method integrating geometric analysis of spur gear pairs with energy method was employed.The impact of assembly errors and tooth surface friction on spur gear pair meshing was investigated.[Methods]A 6-degree-of-freedom bending-torsional coupling vibration model of spur gears was established based on the lumped mass method.Numerical solutions characterizing the meshing behavior and dynamic response of the system were obtained using the Runge-Kutta method.[Results]The analysis reveals that,the mesh stiffness amplitude of the spur gear pair decreases with the increase of the tooth surface friction coefficient.Additionally,simulation results demonstrate that appropriately adjusting the installation conditions and using reasonable tooth surface friction coefficients of spur gear pairs can improve its transmission accuracy and vibration characteristics.The research findings can provide references for the dynamic analysis of spur gear transmission systems under the influence of systematic errors.
