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 kinematic pair inertia and a hard steel ball make this motor continuously word 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 trial speeds, it is wider in speed regulating range. 6. Simple structure and easy maintenance.
