Introduction to the vane hydraulic motor

       叶片式液压马达的输出转矩与液压马达的排量和液压马达进出油口之间的压力差有关,其转速由输入液压马达的流量大小来决定。由于液压马达一般都要求能正反转,所以叶片式液压马达的叶片要径向放置。为了使叶片根部始终通有压力油,在回、压油腔通人叶片根部的通路上应设置单向阀,为了确保叶片式液压马达在压力油通人后能正常启动,必须使叶片顶部和定子内表面紧密接触,以保证良好的密封,因此在叶片根部应设置预紧弹簧。叶片式液压马达体积小、转动惯量小、动作灵敏、可适用于换向频率较高的场合;但泄漏量较大、低速工作时不稳定。因此叶片式液压马达一般用于转速高、转矩小和动作要求灵敏的场合。
