The hydraulic motor is a hydraulic actuator system, the liquid pressure will pump energy into mechanical energy provided by its output shaft (torque and speed). 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. Gear motors reversing the structure in order to meet the requirements, equal access to the oil port with symmetry, with separate leakage oil port, the bearing part leak oil output housing outside; in order to reduce friction torque to start the pump aftermarket power source, using Rolling; in order to reduce torque ripple, hydraulic motor gear teeth to be more than a gear pump. Gear hydraulic motor by dry poor sealing, low rent capacity efficiency, enter the oil pressure is not too high, you can not have a greater torque. And instantaneous changes in speed and torque as the position of the engagement point varies, and therefore the gear hydraulic motor is only suitable for high speed low torque applications. Generally used for construction machinery, agricultural machinery, and even less demanding torque equipment.
