面向行星滚柱丝杠副载荷均布的螺纹牙修形方法
|
摘要
基于行星滚柱丝杠副(PRSM)螺纹牙载荷分布和螺纹牙受载变形关系,提出了滚柱螺纹牙的一种修形方法。采用不同的修形量分别对螺母侧和丝杠侧滚柱螺纹牙进行修形,并对修形后的螺纹牙载荷分布进行计算分析,结果表明,滚柱螺纹牙修形对接触对的载荷分布有较大的影响,螺母侧和丝杠侧载荷分布对修形量的敏感程度不同。通过滚柱螺纹牙修形量对螺纹牙载荷分布的影响规律研究,得到了在文中所给PRSM参数下,螺母侧和丝杠侧滚柱螺纹牙修形量的最优值,可以为未来PRSM均载设计提供理论指导。
Based on the relationship between the load distribution and the load deformation of the thread of the planetary roller screw mechanism( PRSM),a modification method of the roller thread is proposed. The nut side and the screw side of the roller thread are modified by different amount of modification,and the modified thread load distribution is calculated and analyzed. The results show that the effects of roller thread modification on the load distribution are significant,and the sensitivity of the load capacity of the nut and screw to the modification is different. Through the study of the influence of roller thread modification on thread load distribution,the optimal value of the roller thread modification on the nut side and the screw side is obtained under the PRSM parameters given in this paper,which provides a theoretical guidance for the future PRSM load balancing design.
