Yuzheng HydraulicQJMSteel Ball Hydraulic Motor

Steel Ball Motor forms hydraulic transmission devices with various oil pumps, valves, and hydraulic components. Due to certain design measures, it can adapt to various machine working conditions. This type of motor offers advantages such as light weight, compact size, wide speed regulation range, stepwise variable displacement, reliable operation, and long service life. It is currently used in mining engineering, lifting and transportation, metallurgy, shipbuilding, machine tools, plastic processing, geological exploration, and other fields. It is mainly applied in crawler travel, track wheel drive, various rotary mechanisms, exploration drilling, winch lifting, belt transmission, material mixing, road cutting, ship propulsion, plastic injection, and other areas.

    ■ Performance Features
      1. The rolling element of this motor uses a single steel ball instead of two or more rollers and beams commonly used in internal curve hydraulic motors, resulting in a simple structure,
         reliable operation, and significantly reduced size and weight.
      2. The motion pair has low inertia, and the steel ball is sturdy and reliable, allowing this motor to operate continuously under high speeds and impact loads.
      3. The friction pair is small, the distribution oil shaft and rotor are internally force-balanced, the piston pair has hydrostatic balance and good lubrication conditions, and a soft plastic ball cushion is used to seal high
         pressure oil, resulting in high mechanical and volumetric efficiency.
      4. Since the distribution oil shaft is rigidly connected to the stator, this motor allows the use of steel pipes for inlet and outlet oil connections.
      5. This motor has two-stage and three-stage variable displacement, providing a wide speed regulation range.
      6. Simple structure, easy disassembly and repair.
      7. The output shaft of the standard hydraulic motor in this series generally only allows torque and cannot withstand radial and axial external forces. The *QJM*-**Z type hydraulic motor
         output shaft can withstand radial and axial external forces.
      8. The **QJM**-**T** type motor has a central through-hole, allowing a rotating shaft to pass through the hydraulic motor.
