摘要
为优化行星滚柱丝杆的设计,对标准式行星滚柱丝杠的运动原理进行了分析,得出丝杠、滚柱和螺母的螺纹旋向和头数的关系;建立行星滚柱丝杠三维模型,运用ANSYS Workbench软件进行螺纹的接触应力有限元仿真分析;并研究螺纹的牙型角和螺距对接触应力的影响。该分析结果可为行星滚柱丝杠的设计及选型提供参考依据。
To optimize the design of planetary roller screw,the motion principle of standard planetary roller screw is established,and the relationship between screw,roller and nut thread direction and head number is abtained.The three-dimensional model of planetary roller screw is built,and ANSYS Workbench software is used to simulate the contact stress of thread by finite element method.The influence of thread profile angle and pitch on contact stress is studied.The analysis result provides reference basis for the design and model selection of planetary roller screw.
