Network optimization information:

Multiple acting internal curved plunger motor This motor has a displacement twice that of a single stroke motor. It is equal to having a ZI plunger. When the number of equivalent plungers increases, under the same working pressure, the output torque increases correspondingly and the torque fluctuation rate decreases. Sometimes the motor is made into multi row plugs, with more plungers, larger output torque and smaller torque pulsation. So what this motor can do is large displacement, and Small hydraulic motor It can run smoothly at very low speed.

Features: small size, light weight, reliable operation, large output torque, high pressure resistance. Disadvantages: complex structure, difficult manufacturing and high cost.

Shaft plunger motor

Its working principle is the axial plunger motor, the oil distribution plate and swashplate are fixed, and the motor shaft rotates with the cylinder block. Through the window on the oil distribution plate, the pressure oil is extended from the plunger hole to combine the plunger with the swashplate on the swashplate to produce a positive and negative force p on the plunger, which can be divided into the axial component and the vertical component Q. When Q is balanced with the hydraulic pressure on the plunger, the plunger produces torque on the cylinder center, Micro hydraulic motor Drive motor shaft rotates counterclockwise. The instantaneous total torque generated by the shaft plunger motor is fluctuating. When the input direction of pressure oil changes, the output direction of motor shaft also changes. The change of swashplate inclination a, that is, the change of displacement. The greater the swashplate inclination, the greater the torque generated and the lower the speed.
