Abstract : the contraction self - energizing overrunning spring clutch is a new type of overrunning clutch . based on the analysis of forces , the calculating formula of overriding friction torque is derived , it laid down a foundation for design and application of this kind of new clutch 文摘:收缩式自激超越弹簧离合器是一种新型离合器，在对其进行受力分析的基础上，推导出超越时摩擦力矩计算式，为该种离合器的设计与应用奠定基础。
The paper introduces its work principle , analyzes self - locking , transmission capacity , work loss and compares it with roller overrunning clutch . generally considering the size , self - locking capacity and other constraint conditions of new overrunning clutch , an optimizing design is adopted 本文介绍了低副单向超越离合器的工作原理,对超越离合器的自锁原理、传动能力、功损耗等方面进行了分析,与滚柱式超越离合器进行了比较。
The paper designs a lower pair and one - way overrunning clutch . because its arc - block , outer ring , roller , slide - block and output shaft contact by lower pairs , they overcome higher pairs ’ shortcomings such as wearing easily , bad resistance to impact , bad bearing capacity and so on 本文创新设计了一种低副单向超越离合器,其弧块与外环,弧块与滚柱,滚柱与滑块以及滑块与输出轴之间都是以低副联接,克服了高副易磨损、耐冲击性差,承载力低等缺点。
After designing oil ditches on the surface of its arc - block , increase friction factor and make sure self - lock which solves above problem . do qualitative analysis to lower pair and one - way overrunning clutch and inner star - wheel - roller overrunning clutch by using self - made lever loader . the experiment shows : on the same condition , the deformation of new overrunning clutch ’ s surface contact with lower pair is smaller than the deformation of roller overrunning clutch ’ s line contact with higher pair and new overrunning clutch ’ s skid angle is smaller 对低副单向超越离合器的部件进行了加工制造,在超越离合器弧块表面创新设计加工排油沟,增大摩擦系数,保证实现自锁,解决了很多离合器工作过程中容易出现无法自锁的问题;对低副单向超越离合器和内星轮滚柱超越离合器用自制杠杆加载器做了定性分析,实验表明:相同条件下,新型离合器低副面接触比滚柱离合器高副线接触变形小、溜滑角小。
It introduces research background of the paper , research states of in home and abroad , major research content , classifying and operating principle of sprag overrunning clutch . a method is discussed for sprag overrunning clutches design , including configuration design , force analysis and fea . a computer program is developed and applied to the h - tech project 本文首先简要介绍了论文研究的背景、国内外的研究现状、主要研究内容、超越离合器的分类和斜撑超越离合器的工作原理；然后，详细阐述了运用现代先进技术开发高速斜撑超越离合器的结构设计方法、受力计算方法和有限元分析方法。
