摘　　要：应用数值算法计算空间点接触赫兹接触系数,计算出无隙摆线钢球传动啮合副啮合刚度系数。利用啮合点刚度系数求解行星盘转角变形;基于行星盘转角变形,以偏心输入轴转角为参变量,对啮合刚度系数进行等效简化,求出等效简化后啮合刚度系数计算公式,并对影响因素进行分析。结果表明:等效简化啮合刚度系数是啮合副结构几何尺寸的函数且具有时变性,并随偏心轴输入轴转角按正弦曲线关系变化。文中研究为精密摆线钢球传动啮合副动力特性分析提供了方法,完善了精密摆线钢球传动的动力学理论。Hertz contact coefficient of space point contact is calculated by using numerical algorithm and the contact stiffness of cycloid ball meshing pair is calculated. The angle deformation of planetary disc is calculated by using contact stiffness;Based on the angle deformation and the parameter of the eccentric angle of the input shaft, the contact stiffness is equivalent simplified and the influence factors are analyzed. The results show that the simplified is the function of the meshing pair geometry itself and is time-varied, and the meshing stiffness coefficient changes with the eccentric input shaft angle as the sine relationship. This research supplies a method for the dynamic analysis of the cycloid ball meshing pair, and it perfects the dynamics theory of the no clearance precision steel ball transmission.
