Hydraulic motor, also known as motor oil, mainly used in injection molding machinery, ships, from Jan machines, construction machinery, construction machinery, mining machinery, mining machinery, metallurgical machinery, shipbuilding, machinery, petrochemicals, port machinery. High-speed motor gear motor with a small size, light weight, simple structure, technology is good, is not sensitive to the oil pollution, impact resistance and inertia is small. Disadvantages greater torque ripple, low efficiency, starting torque is small (only 60% of the rated torque of --70%) and poor low-speed stability. Hydraulic motors generally require inversion, so the internal structure should have symmetry, but the hydraulic pump is generally maintained in one direction of rotation (hydraulic pump), do not have this requirement. In order to reduce oil absorption resistance, reducing the radial force maintenance (pumps), general pump suction port than the size of a big oil port. Low pressure and the pressure of the hydraulic motor is slightly higher than the atmospheric pressure chamber, so there is no above-mentioned requirements. Hydraulic motor requirements can work in a wide speed range, therefore, should be used hydraulic bearings or hydrostatic bearings. Because when the motor speed is low, the use of hydrodynamic bearings, it is not easy to form a lubricating synovial. Vane pump with rotor blades together rely on high-speed rotation of the centrifugal force generated by the inner surface of the stator blade is always snapped, and from seal oil, the formation of the working volume. If its use as a motor, blade root must be spring loaded hydraulic motor to ensure that the inner surface of the stator blade is always snapped to the normal starter motor. Pump in the structure need to ensure self-priming capability Training (pump), but it is not required for the hydraulic motor. Hydraulic motor must have a large starting torque. So-called starting torque, the motor is activated by a stationary state, the torque of the motor can output shaft, the torque is normally greater than the torque running state is in the same working pressure, therefore, in order to make the starting torque as close to the operating condition torque requirement of the motor torque ripple is small, a small internal friction.
