A high mounted hydraulic motor with negative pressure balance, which can improve the current market sales of low speed gears and large torque Hydraulic motor The invention creates a hydraulic motor with high efficiency (high mechanical kinetic energy and volumetric efficiency), high pressure, high installation and further improved application deadline. The basic concept of negative pressure balance is skillfully mastered in the motor to improve the working characteristics of the motor.

1、 Under the condition that everyone's motor leaks liquid in cavity B, the working pressure oil leaks liquid from a plane of the oil distribution plate according to the fast transmission gear Agricultural hydraulic motor From the main oil passage to the other plane, because there is an annular oil groove, the working pressure oil can uniformly act on the plane of the oil distribution plate, thus ensuring that the vertical plane of the oil distribution plate and the surface can work, which can effectively reduce the sliding friction between the middle of the two surfaces during exercise. The leakage of working pressure oil is very small, and the volumetric efficiency is further improved.

2、 In everyone's Drive hydraulic motor In case of leakage in cavity A, the working pressure oil leaks from the round surface of the oil distribution plate to the two planes according to the main oil passage, because after the high pressure oil enters from the oil inlet, there is a safety outlet that can immediately reach the two planes of the motor, the oil in one plane immediately reaches the working upper cavity of the motor, and the oil in one plane flows into the oil inlet according to the clearance between the oil distribution plate and the oil inlet, Therefore, the working pressure oil can also act evenly on the plane of the oil distribution plate, ensuring the vertical plane between the oil distribution plate and the surface to work, effectively reducing the sliding friction force between the two surfaces during exercise and fitness, the leakage of the working pressure oil is very small, and the volumetric efficiency is further improved.

3、 First, 20CrMnTi was selected as the raw material of the hydraulic plunger pump, which is suitable for making important parts that can bear heavy load, destructiveness and friction.

A prompt box covering a very large area is opened on the mating surface between the hydraulic plunger pump and the roller bearing surface, so that the high pressure oil can flow here and cause a driving force to the roller bearing surface, reducing the sliding friction of the two surfaces, thus ensuring the balance of negative pressure, making the motor run more smoothly and smoothly, and improving the mechanical kinetic energy.
