QJM series hydraulic motor

Model   QJM series

Displacement    63-1000ml/r

Torque   93-15000N.M

QJM series hydraulic motors can constitute a hydraulic actuator with different oil pumps, valves and hydraulic parts. They are able to adapt themselves to all kinds of mechanical conditions by reason of some measures taken to their designs. 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. As this model has variable displacements dual and trial speeds, it is wider in speed regulating range. That one of Z series hydraulic motor can endure outside radial and axial forces. As T series hydraulic motor has a central through hole, the rotating shaft can pass through the motor.

Features
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 kinematics' 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. That one of Z series hydraulic motor can endure outside radial and axial forces. As T series hydraulic motor has a central through hole, the rotating shaft can pass through the motor.
