Plunger Type High Speed Hydraulic Motor


Multi-action internal curve plunger motor, the motor is composed of the distribution shaft 1,hydraulic motor the cylinder 2, the plunger 3, the beam 4, the roller 5, the stator 6 and the output shaft 7. The displacement of this motor is doubled compared to a single-stroke motor. Equivalent to 21 plungers. As the number of equivalent plungers increases, under the same working pressure,hydraulic motor the output torque increases correspondingly, and the torque pulsation rate decreases. Sometimes this kind of motor is made of multiple rows of plungers, the number of plungers is more, the output torque is further increased,hydraulic motor and the torque pulsation rate is further reduced. Therefore, this kind of motor can be made into a large displacement, and can run smoothly at a very low speed. Since the motor needs to rotate in both directions,hydraulic motor the blade slots are arranged radially.

Plunger-type high-speed hydraulic motors are generally axial. Axial piston motor: In addition to valve-type flow distribution, axial piston pumps can be used as hydraulic motors in other forms in principle,hydraulic motor that is, axial piston pumps and axial piston motors are reversible. The working principle of the axial piston motor is that the oil distribution plate and the swash plate are fixed,hydraulic motor and the motor shaft is connected with the cylinder body to rotate together. When the pressure oil enters the plunger hole of the cylinder body through the window of the oil distribution plate,hydraulic motor the plunger extends out under the action of the pressure oil and closes to the swash plate to produce a normal reaction force p to the plunger,hydraulic motor which can be decomposed into Axial force and vertical force Q. Q is balanced with the hydraulic pressure on the plunger,hydraulic motor and Q makes the plunger generate a torque on the center of the cylinder, driving the motor shaft to rotate counterclockwise. The instantaneous total torque produced by the axial piston motor is pulsating.

If the input direction of the motor pressure oil is changed, the motor shaft will rotate in a clockwise direction. The change of the inclination angle a of the swash plate, that is,hydraulic motor the change of displacement, not only affects the torque of the motor, but also affects its speed and steering. The greater the tilt angle of the swash plate,hydraulic motor the greater the torque produced and the lower the speed.
