The difference between the number of teeth of the gear hydraulic motor
In order to meet the requirements of forward and reverse rotation in structure, the gear hydraulic motor has equal and symmetrical oil inlet and outlet ports and a separate oil drain port to lead the leakage oil from the bearing part out of the housing; in order to reduce the starting friction torque, rolling bearings are used; in order to reduce the rotation torque pulsation, the gear hydraulic motor has more teeth than the pump. The gear hydraulic motor has poor dry sealing, low volumetric efficiency, high input oil pressure, and cannot generate large torque. And the instantaneous speed and torque change with the position of the meshing point, so the gear hydraulic motor is only suitable for high-speed and low-torque occasions.
