radial piston motor meaning in English

径向活塞式马达
径向柱塞马达

To directly estimate the life of this kind of motor , and to design a orbit curve with the longest life at same condition , this paper gives theoretic research of the equal contact stress inner curve of radial piston motor . the research is divided into four parts : 1 ) taken all forces the piston endured into consideration when radial piston motor working , the force between roller ( or ball ) and orbit is deduced . the simple style of the press expression can be confirmed by ignoring minor influence factors after analysis all factors that will influence this press
静压传动技术在各类工程机械中得到广泛的应用，对作为其核心部件的径向柱塞式低速大扭矩液压马达的研究显得十分重要，为了能直接对这种马达进行寿命估计，并能在相同工况下求得寿命最长的轨道曲线，本文从设计等接触应力内曲线的角度对这类马达作探讨性的研究，主要从以下四个方面进行： ( 1 )综合考虑径向柱塞式液压马达工作时的各种主要受力状况，对柱塞组件进行受力分析，并通过仿真分析影响轨道和滚动体间正压力的各个因素，得到正压力的简化表达式。
