【摘要】 基于非对称渐开线圆柱齿轮传动时的啮合机理和齿轮系统动力学,同时考虑到齿轮系统时变啮合刚度和静态传递误差的影响,建立了齿轮动力学模型,利用数值积分和数值仿真方法对其进行了非线性振动研究。比较了标准齿轮与非对称齿轮的振动特性,分析了齿轮系统各参数对系统动态特性的影响。仿真结果对考虑动载荷情况下的油膜厚度计算提供了基础数据,为进一步研究非对称渐开线的各种特性提供了理论依据。更多还原

【Abstract】 The dynamic model of unsymmetric gear was proposed on the basis of mesh characteristics of involute gear transmission with unsymmetric teeth and dynamics of gears system,and the effect of time-varying mesh stiffness and static transmission error of gears system.By applying the method of numerical integral and numerical simulation to the research on nonlinear vibration,vibration characteristics were compared between standard and unsymmetric teeth,and the effect of unsymmetric gear parameters on the dynamic characteristics of transmission system were studied.The simulation results provide basic data for the thickness calculation of oil film considering dynamic load,and valuable theoretical basis for further research on involute gear with unsymmetric teeth and double pressure angles.更多还原
