摘　　要：自行设计了一种新型的轴向柱塞式液压马达 ,它突破了传统轴向柱塞式液压马达中柱塞球形端部紧压在斜盘斜面上的设计 ,用螺旋面取代斜面 ,使柱塞的受力方向改变 ,马达的输出转矩增加。在此基础上 ,对柱塞运动进行了分析。结果表明 ,该马达的柱塞沿轴向运动的加速度在封油区和工作区为零 ,在过渡区为常数 ,即柱塞沿轴向方向的运动平稳。A new axial plunger hydraulic motor is developed. In the motor,the bulb end of plungers is pressed on a spiral plate by the high pressure oil,substitute on the conventional inclined plate. The force of plungers is changed directionally,therefore the output torque and the efficiency increase largely.The move of plungers is analyzed,the result is indicated that the axial acceleration component of the motor is zero, in other words, the move of plungers is even and shock free axially.
