1. Since there is no lateral force between the piston and the swing cylinder, the bottom of the piston is designed to be statically balanced, and the torque is transmitted between the piston and the crankshaft through the rolling bearing, thereby reducing the friction loss during transmission. Therefore, the GM series hydraulic motors are characterized by high mechanical efficiency and high starting torque (mechanical efficiency above 0.92 at start-up).
2. The plane distributor is simple and reliable, improves the sealing performance, has good low-speed stability and less leakage. There is no leakage between the piston and the rotary cylinder with a plastic piston ring seal, so it has a high volumetric efficiency (up to 0.98).
3. Since the structure reduces friction loss and improves sealing performance, it has good low-speed stability, can run smoothly under 1r/min working conditions, and has a large speed regulation range (speed regulation ratio can reach 1000)
4. The sleeve sleeve of the piston and bearing is firmly connected to the snap ring without clearance, so this series of hydraulic motors can operate under pump conditions. After closing the oil inlet, the motor can run at high speed under idle conditions.
5. This series of hydraulic motor has high pressure and pressure up to 45MPa. Light weight, small size, high power.
6. Due to the simple structure and reasonable design, the bearings used have a large carrying capacity, so the operation is reliable, the life is long, the noise is low, and the transmission bearing is allowed to be reversed by radial load and rotation direction.
