中文摘要：

水压马达是以淡水或海水为工作介质,并能将水压能转换为机械能实现连续回转运动的水压执行元件,在水压传动系统中有着广泛的应用.本文对国内外在高速水压马达,如水压柱塞马达、水压叶片马达,以及在低速大扭矩的径向柱塞多作用内曲线水压马达方面的研究成果进行综述,并对其发展前景进行展望,供水压传动的研究人员参考。

英文摘要：

The water hydraulic motor is a kind of water hydraulic actuator with fresh water or sea water as the working fluid,which can rotate continuously and transfer water hydraulic energy into mechanical energy,applied widely in water hydraulic transmission system.In this paper,the research achievements on water hydraulic motors are summarized,especially on high-speed water hydraulic motors such as the water hydraulic piston motor and the water hydraulic vane motor,and on low-speed high torque water hydraulic motors such as the radial piston motor with multi-action inner curve stator.The development prospect of water hydraulic motor is presented.The paper is a reference for researchers of water hydraulic transmission.
