摘　　要：结合行星滚柱丝杠传动副接触特点,基于Hertz接触理论开展了传动副接触模型研究,提出一种研究传动副静态接触状态下接触力与接触力分布的分析方法。通过有限元分析方法进行验证,结果表明,该方法合理可行,可用于传动副静态接触特性研究,并为进一步开展相关静态与动态特性研究打下了基础。Based on Hertz contact theory, this paper studies the contact model of the planetary roller screw drive pair considering the contact characteristics of the drive pair. An analysis method is put forward to study the contact force and its distribution under the static contact state of the drive pair. The results of finite element analysis show that the method is reasonable and feasible. The method can be used for the study of the static contact characteristics of the drive pair, and provide the basis for the further research of static and dynamic characteristics of planetary roller screw.
