Problems solved by technology

Due to the relative rotation between the oil distribution plate and the cylinder body, they will wear each other to form an end face gap. The leakage of the hydraulic motor mainly comes from the end face leakage between the oil distribution plate and the cylinder body. major obstacle to stress

Abstract

The invention relates to an oil matching mechanism for a hydraulic motor, which aims at providing a plunger type quantitative hydraulic motor liquid switch torque-converting and oil-matching component. The oil-matching component comprises plungers, an oil-matching valve group and a liquid torque-converting driving mechanism, wherein, the oil matching valve group is composed of integrated valves ofidentical number of the plungers; each integrated valve is composed of a high-speed switch high pressure oil supplying valve and a corresponding high-speed switch oil discharging / complementing valve;each high speed switch oil discharging / complementing valve is provided with an oil return hole, and each high speed switch high pressure oil supplying valve is provided with a pressure oil hole; thetail part of a push and pull rod penetrates out of a spring cavity of the high speed switch high pressure oil supplying valve and is connected with the liquid torque-converting driving mechanism; theliquid torque-converting driving mechanism is used for driving the integrated valves to work. The hydraulic motor has the advantages that the torque-converting control of the switch can be realized; alarge quantity of energy consumption can be saved; the driving pressure of the hydraulic motor is greatly improved.

Description

technical field [0001] The invention relates to a hydraulic motor oil distributing mechanism, in particular to a plunger type quantitative hydraulic motor hydraulic switch variable torque oil distributing assembly. Background technique [0002] The plunger hydraulic motor relies on the pressure oil to act on the plunger so that the motor output shaft obtains a certain torque. In order to make the plunger communicate with the pressure oil port and the oil return port alternately, a flow distribution device must be used. At present, the plunger hydraulic motor Most of the end face distribution is used, and the main device used in the end face distribution is the oil distribution plate. The oil distribution plate is similar to a plate valve. A plane with two arc-shaped ("waist") windows is attached to the end face of the cylinder block with a flow distribution hole, so that the cylinder block and the oil distribution plate are on the surface perpendicular to the motor shaft. R...
