摘　　要：为揭示行星滚柱丝杠螺纹副-齿轮副同步啮合动态滑动特性,推导了行星滚柱丝杠滑动角计算方法,建立了行星滚柱丝杠数值模型,验证了滑动角计算方法的准确性。首先,基于节圆偏移产生机制,建立了滑动角运动学分析模型,通过与数值解对比,验证其准确性;在此基础上,分析了丝杠转速、螺母负载对滑动角大小以及螺纹副、齿轮副滑动距离的影响规律。结果表明,滑动角随着丝杠转速、螺母负载的增大而增大;滚柱-丝杠侧滑动距离远大于滚柱-螺母侧,且均随着丝杠转速、螺母负载的增大而增大;齿轮副滑动距离随丝杠转速增大而减小,随螺母负载增大而增大。To reveal the dynamic sliding characteristics of synchronous meshing of thread pairs and gear pairs of the planetary roller screw mechanism,a calculation method for the sliding angle of the planetary roller screw mechanism was proposed,and a numerical model of the planetary roller screw mechanism was established to verify the correctness of the sliding angle calculation method.Firstly,based on the mechanism of the pitch cir⁃cle offset,the kinematics analysis model of the slip angle was established,and its correctness was verified by comparing with the numerical solution.On this basis,the influences of the screw speed,nut load on the sliding angle and the sliding distance of thread gear and gear pairs were analyzed.The research results indicate that the sliding angle increases with the increase of the screw speed and the nut load.The sliding distance on the roller screw side is much greater than that on the roller nut side,and both increase with the increase of the screw speed and the nut load.The sliding distance of the gear pair decreases with the increase of the screw speed and increas⁃es with the increase of the nut load.
