QJM type Hydraulic motor Composed of various hydraulic oil pumps, valves and hydraulic accessories Hydraulic transmission device In consideration of the fact that it has adopted certain countermeasures in its conception, it can meet the working conditions of all kinds of equipment. This type of motor has the advantages of light weight, small equipment volume, large range of speed change, stepwise variable, reliable operation and long service life. At present, it has been used in mining engineering, lifting and logistics transportation, metallurgy industry, shipbuilding, CNC machine tools, injection molding, geological exploration and other fields. It is mainly used for crawler walking, track driving wheel driving, various slewing mechanisms, exploration drilling rigs, winch lifting, drag drive, material mixing, ground cutting, ship manufacturing driving, plastic injection and other parts.

1. The rolling element of this type of motor is replaced by a steel ball Inner curve hydraulic motor More than 2 rollers and bearing beams are used, so the structure is simple, the operation is reliable, and the volume and net weight are significantly reduced.

2. The operating inertia force is small, and the steel ball is firm and reliable, so this type of motor can rotate at a high speed and run continuously under impact load.

3. There are few friction pairs. The internal forces of the oil distribution shaft and rotor are stable and balanced. The ball pad made of self-lubricating bearing polymer material transmits force. The ball plug pair has the necessary conditions for static pressure stable balance and excellent lubrication. The soft plastic piston that can automatically compensate for wear is used to seal high-pressure oil, so it has high mechanical equipment and capacity working efficiency, It can operate stably at a very low rotating speed, and the operating torque is relatively small

Large.

4. Due to the characteristics of the structure, the return oil back pressure required by the motor is low, generally 0.3-0.8Mpa. The higher the rotation speed, the greater the back pressure.

5. Since the oil distribution shaft is rigidly connected with the stator, the oil delivery pipe of this type of motor is allowed to be connected with a round steel pipe.

6. This type of motor has two-stage and three-stage variable displacement, so it has a relatively large range of speed changes.

7. The structure is simple and easy to disassemble. There is no special requirement for oil cleanliness. The precision of the oil filtration system can be selected according to the needs of the supporting facilities hydraulic oil pump.

8. Except for the shell type and the supported type, the outlet shaft of the hydraulic motor is usually only allowed to withstand torque, not radial and axial forces.

9. With "T-type hydraulic motor, the center point has a through hole, and the rotating shaft can pass through the hydraulic motor.

10、 The hydraulic motor with "S" type is equipped with a mechanical equipment braking system that can automatically open and close, and can achieve reliable braking system.

11、 With "Se" and "SeZ 'type hydraulic motors, the operation and braking system can be controlled manually or automatically, the regulating working pressure is low, the torque of the braking system is large, and the actual operation is convenient and reliable.

12、 The rear end of the hydraulic motor with "B" type can be developed to assemble a speedometer to show the rotation speed of the hydraulic motor.
