Qjm Sphere Piston Motor, Sphere Piston Hydraulic Motor

QJM hydraulic motor that can constitute a hydraulic actuator with different oil pumps, valves and hydraulic parts is able to adapt itself to all kinds of mechanical conditions by reason of some measures taken to its design. The motor has many advantages, e.g. light weight, small size, wide speed regulating range,capable of stepping variation, reliable performance and long useful life, etc. It has been widely applied for mine engineering,hoisting transport, metallurgy, ships, machine tools, plastics processing and geological prospecting, etc. It is mainly used for pedrail walking, driving railway wheels, different slewing gears, drilling, winch hoisting, belt transmission,material agitation, cutting road surfaces, ship propulsion, plastics injection, etc.

 

Characteristics

1. Because the rolling body of this motor is replaced by a steel ball rather than two or more rollers and beams commonly used in inner curve hydraulic motors, it is simple in structure, reliable in performance and greatly reduced in volume or weight.

2. A small kinematic pair inertia and a hard steel ball make this motor continuously work during the rotation at higher speed and under stronger impact load.

3. It has higher mechanical and volumetric efficiency for its small friction pair, oil feed shaft balanced with roller, piston pair capable of static pressure balance & good lubrication and coated high pressure sealing oil on soft plastic mat.

4. As the oil feed shaft and stator are in rigid connection, the oil pipeline of this model can be connected with steel pipe.

5. As this model has variable displacements dual and trinal speeds, it is wider in speed regulating range.

6. Simple structure and easy maintenance.

7. The output shaft of the standard model can only endure the torque rather than outside radial and axial forces, while that one of Z series hydraulic motor can endure outside radial and axial forces.

8. As T series hydraulic motor has a central through hole, the rotating shaft can pass through the motor.
