【摘要】：行星滚柱丝杠副具有承载能力大、环境适应性好、寿命长等优点。行星滚柱丝杠副的承载特性主要包括各啮合传力零件的受力分析、轴向变形、螺纹牙载荷分布、滚柱间载荷分配及摩擦磨损特性等。它既是揭示其服役过程中载荷传递、结构变形以及摩擦磨损等机理的重要途径,也是进一步提高行星滚柱丝杠副传动性能和使用寿命的理论基础。首先介绍了行星滚柱丝杠副承载原理,在此基础上说明承载特性各项研究的主要内容及意义,并对目前研究成果进行了总结与分析。最后,对行星滚柱丝杠副承载特性的未来研究方向进行了展望。
[Abstract]:Planetary roller screw pair has the advantages of large bearing capacity, good environmental adaptability, long life and so on. The load-bearing characteristics of planetary roller screw pairs mainly include the mechanical analysis of various meshing force transfer parts, axial deformation, load distribution of thread teeth, load distribution between rollers, friction and wear characteristics, and so on. It is not only an important way to reveal the mechanism of load transfer, structural deformation and friction and wear, but also a theoretical basis for further improving the transmission performance and service life of the planetary roller screw pair. This paper first introduces the bearing principle of planetary roller screw, and then explains the main contents and significance of the research on the bearing characteristics, and summarizes and analyzes the current research results. Finally, the future research direction of the bearing characteristics of planetary roller screw is prospected.
