Axial piston motor works: In addition to the axial piston pump with valve flow, the other forms can in principle be used as a hydraulic motor, that is, axial piston pump and axial piston motor is reversible. The working principle of the axial piston motor is that the oil pan and the swash plate are fixed, and the motor shaft and the cylinder body are connected to rotate together. When the pressure oil through the window with the oil pan into the cylinder plunger hole, the plunger extended under pressure oil, close to the swash plate swashplate to produce a normal reaction force p, the force can be decomposed into Axial component and the vertical component of force Q. Q is balanced with the hydraulic pressure on the plunger, and Q causes the plunger to generate a torque to the center of the cylinder, causing the motor shaft to rotate counter-clockwise. The instantaneous total torque produced by an axial piston motor is pulsatile. If you change the motor pressure input direction, the motor shaft rotates clockwise. The change in the inclination a of the swash plate, ie, the displacement, affects not only the torque of the motor but also its speed and direction of rotation. Axial piston pump swashplate inclination, the greater the torque, the lower the speed.
