Description

technical field [0001] The invention relates to the field of manufacturing gear pumps and gear motors, in particular to an internal meshing gear motor with high volumetric efficiency, which can be used not only as a pump but also as a motor. Background technique [0002] The gear motor is a hydraulic motor that inputs pressure fluid to rotate two gears that mesh with each other in the pump casing. In order to meet the requirements of forward and reverse rotation, the structure of the gear pump motor has equal oil inlet and outlet, which is symmetrical. The oil inlet and return channels of the gear motor are symmetrically arranged, and the apertures are the same, so that the performance of the motor is the same when it is forward and reverse. The oil drain hole has a separate external oil drain port to lead the leaked oil inside the shell out of the shell. The main products on the market today are external gear motors, which have large torque pulsation, large leakage, high i...
