Network optimization information:

The radiation force produces torque on the cylinder block, which makes it rotate. The transmission shaft in the cylinder block is connected by the end face to output torque and speed. The above analysis is about the torque generated by a plunger. Since there are multiple plungers in the oil pressure area, the torque generated on the plunger will cause the cylinder to rotate, resulting in torque. Axial plunger hydraulic motor It is mostly used in low speed and high torque conditions.

Shaft plunger motor

In principle, other forms of axial piston pump can be used as Hydraulic motor In use, the axial plunger pump and the axial plunger motor can be reversed. Cabin opener hydraulic motor The working principle of the shaft plunger motor is that the oil distribution plate 4 and swashplate 1 are fixed, and the motor shaft 5 and the cylinder 2 are connected to rotate together. The pressure oil is sent into the plunger hole of the cylinder block 2 through the window of the oil distribution plate 4, and the plunger 3 is extended by the pressure oil. When Fz is in balance with the hydraulic pressure on the plunger, Fy makes the plunger produce torque to the center of the cylinder block, and drives the motor shaft to rotate counterclockwise. The instantaneous total torque generated by the shaft plunger motor is fluctuating. If 530 Cycloidal hydraulic motor pressure If the oil input direction changes, motor shaft 5 rotates clockwise. The change of swashplate angle a, that is, the change of displacement, not only affects the torque of the motor, but also affects the speed and steering of the motor. The larger the inclined disk angle, the greater the torque generated and the lower the speed.
