Swing cylinder hydraulic motor It is a new type of product that our factory has carried out structural design optimization based on years of project experience and Italian technology application. H GM Hydraulic Motor The main features are as follows: 1. Considering that the piston parts and the swing cylinder do not have side forces, the bottom structure of the piston parts is designed to be statically stable and balanced, and the thrust between the piston parts and the crankshaft can be transmitted through roller bearings, reducing the friction loss during the operation of force transmission, so the HGM series Hydraulic motor It has the characteristics of high mechanical energy and high starting torque (above 0.92 mechanical energy during starting). 2. The plane valve distributor (invented by zhuanli) is simple and reliable, with good sealing function and very little leakage. The piston parts and the swing cylinder are sealed with plastic piston rings without leakage, so it has a high volumetric efficiency (can reach 0.98). 3. Considering that the structure reduces the friction loss and improves the sealing function, the low speed stability performance is very good. It can operate stably at 1r/min and has a wide range of speed changes. 4. Considering that the piston part and bearing sleeve can be firmly attached by the hook without clearance, the whole series of hydraulic motors can operate as pumps. 5. This series of hydraulic motors has high working pressure, light weight, small equipment volume and high specific power. 6. Considering the simple structure, scientific and reasonable structure design, the rolling bearing with high load level is selected, so the operation is reliable, the service life is long, the noise is low, the rotating shaft is allowed to bear radial load, and the direction of rotation is reversible.

        Internal five-star motor The basic working principle of is that the oil distribution plate is fixed, and the motor crankshaft and piston parts can transmit torque to each other through roller bearings. When the working pressure oil enters the engine cylinder block through the window of the oil distribution plate to drive the piston parts, the piston parts extend under the action of the working pressure oil, and form a radial reaction force p against the piston parts closely against the crankshaft, This force is decomposed into axial component and vertical component Q. Q is in balance with the hydraulic working pressure on the piston part, and Q makes the piston part form a turning distance to the central point of the crankshaft, and the drive motor shaft rotates counterclockwise. If the input direction of motor working pressure oil is changed, the motor shaft rotates clockwise.
