轴向柱塞马达

轴向柱塞泵除阀式配流外，其它形式原则上都可以作为液压马达用，即轴向柱塞泵和轴向柱塞马达是可逆的。轴向柱塞马达的工作原理为，配油盘和斜盘固定不动，马达轴与缸体相连接一起旋转。当压力油经配油盘的窗口进入缸体的柱塞孔时，柱塞在压力油作用下外伸，紧贴斜盘斜盘对柱塞产生一个法向反力p，此力可分解为轴向分力及和垂直分力Q。Q与柱塞上液压力相平衡，而Q则使柱塞对缸体中心产生一个转矩，带动马达轴逆时针方向旋转。轴向柱塞马达产生的瞬时总转矩是脉动的。若改变马达压力油输入方向，则马达轴按顺时针方向旋转。斜盘倾角a的改变、即排量的变化，不仅影响马达的转矩，而且影响它的转速和转向。斜盘倾角越大，产生转矩越大，转速越低。

Axial plunger motor

Except for valve type flow distribution, axial piston pumps can generally be used as hydraulic motors in other forms, that is, axial piston pumps and axial piston motors are reversible. The working principle of an axial piston motor is that the oil distribution plate and swashplate are fixed, and the motor shaft is connected to the cylinder body to rotate together. When the pressure oil enters the plunger hole of the cylinder block through the window of the oil distribution plate, the plunger extends under the action of the pressure oil, and tightly adheres to the swashplate to generate a normal reaction force p on the plunger. This force can be decomposed into axial component force and vertical component force Q. Q is in balance with the hydraulic pressure on the plunger, while Q causes the plunger to generate a torque towards the center of the cylinder block, driving the motor shaft to rotate counterclockwise. The instantaneous total torque generated by the axial piston motor is pulsating. If the direction of motor pressure oil input is changed, the motor shaft rotates clockwise. The change in inclination angle a of the swashplate, also known as the change in displacement, not only affects the torque of the motor, but also its speed and steering. The larger the inclination angle of the swashplate, the greater the torque generated and the lower the rotational speed.
