摘　　要：为深入分析斜齿轮传动的动态啮合特性,构建了斜齿轮啮合副的柔性动力学模型,应用多体动力学方法对啮合副动态特性进行了仿真分析,采用单因素法研究了不同负载、不同变位系数及不同螺旋角对斜齿轮传动的动态传动误差、轮齿最大受力、轮齿最大滑动速度的影响。研究表明,变位系数对传动误差、轮齿最大受力及最大滑动速度的影响相关性一致;螺旋角对传动误差、轮齿最大受力的影响相关性相同,但不同于螺旋角对最大滑动速度的影响。In order to analyze the dynamic meshing characteristics of helical gear transmission,a flexible dynamic model of the helical gear meshing pair is built,and the dynamic characteristics of the meshing pair are simulated and analyzed by the multi-body dynamics method.The single factor method is used to study the influence of different loads,different modification coefficients and different helix angles on the dynamic transmission error of helical gear transmission,the maximum force on the gear teeth,and the maximum sliding speed of the gear teeth.The research results show that the influence of the displacement coefficient on the transmission error,the maximum force of the gear teeth and the maximum sliding speed are consistent.The helix angle has the same correlation to the influence of the transmission error and the maximum force on the gear teeth,but it is different from the effect of the helix angle on the maximum sliding speed.
