针对循环式行星滚柱丝杠副螺母存在无螺纹区的特殊结构特点,提出了螺母无螺纹区的设计方法,推导了螺母无螺纹区的结构参数相关公式。在此基础上,根据滚柱与丝杠和螺母啮合的实际情况,构建了滚柱、丝杠和螺母截面设计方法,通过调整两斜边与圆弧和斜边的间隙以提高丝杠与滚柱、滚柱与螺母螺纹的啮合精度。为确保滚柱与丝杠和螺母啮合,给出了不同滚柱中心面到凸轮环端面距离的关系式,并结合循环式行星滚柱丝杠副的工作原理与结构组成,根据其相关结构参数建立零件模型,完成了虚拟装配。提出的螺母无螺纹区设计和虚拟装配方法可为循环式行星滚柱丝杠副的设计分析提供参考。
The nut threadless area of the circulating planetary roller screw mechanism design method is proposed based on the specific structural characteristics of its nut, and related formulas are derived for the structural parameters of the nut threadless area. On this basis, a cross-section design method for rollers, screws, and nuts is developed in accordance with the actual meshing situation of the components. By adjusting the clearance between the two oblique edges and the arc, oblique edges, the meshing accuracy of the screw and roller threads, roller and nut threads can be improved. The relationship between the distance from the center of the rollers to the end of the cam ring is provided to ensure the meshing between the rollers and the screw, the rollers and the nut. Finally, according to the working principle and structural characteristics of the circulating planetary roller screw mechanism, a three-dimensional model is established using its relevant structural parameters, and the relevant assembly is carried out. The design and virtual assembly method of the nut threadless area proposed can serve as a model and guide for the design and analysis of the circulating planetary roller screw mechanism.
