Radial Piston Hydraulic Motor
- Nov 27, 2018 -

The working principle of the radial piston type hydraulic motor, when the pressure oil enters the bottom of the plunger in the cylinder through the window of the fixed oil distribution shaft 4, the plunger protrudes outwardly and tightly against the inner wall of the stator due to the stator and There is an eccentricity in the cylinder. At the point where the plunger is in contact with the stator, the reaction of the stator to the plunger is . The force can be decomposed into two components. When the oil pressure acting on the bottom of the plunger is p, the plunger diameter is d, and the angle between the force and the force is X, the force generates a torque to the cylinder to rotate the cylinder. The cylinder body is further outputted by the end face of the drive shaft to output torque and speed. In the case where the plunger of the above analysis generates torque, since a plurality of plungers act on the pressure oil zone, the torque generated on these plungers causes the cylinder to rotate and output torque.Radial piston hydraulic motors are often used in low speed and high torque situations.
