Description

The serial closed cavity volume circulation increase and decrease device that crank type blade separates

Technical field

The present invention relates to the serial closed cavity volume circulation increase and decrease device that a kind of blade separates, particularly a kind of crank type The serial closed cavity volume circulation increase and decrease device that blade separates.

Background technology

At present, the blade of vane pump or motor is when rotating with rotor coaxial, and the outward flange of blade must be with cartridge type stator Medial wall be in close contact as far as possible, on medial wall, overall process is slided, this slip, makes blade outward flange and stator inner wall produce Raw abrasion；Meanwhile, blade two ends are in close contact with the two end cap inwall of pump respectively, the blade of vane pump or motor with rotor with When axle rotates, blade two ends are omnidistance on the end cap inwall of pump or motor slides, and the two ends of blade and end cap inwall produce abrasion. Above-mentioned two classes abrasions, reduce pump or the volume space bad sealing of the service life of motor, pump or motor, the output pressure of pump or The output moment of torsion of motor is difficult to improve, and unstable properties.

Summary of the invention

The present invention be directed to deficiency present in above-mentioned technology, it is provided that the serial closed cavity that a kind of crank type blade separates Volume circulation increase and decrease device；Can be used as the core component of pump or hydraulic motor；When making pump, it is turning of a kind of former vane pump Son changes mover into, and the most former rotor does not rotates, and is driven the vane pump doing the periodically movement of two coordinates by built-in bent axle；Do liquid During pressure motor, being that the rotor of a kind of former vane motor changes mover into, the most former rotor does not rotates, and drives at highly pressurised liquid The periodicity doing two coordinates under Dong moves, and then the crank rotation that driving mover is built-in, to form new vane motor； The sealing of the volume space of this pump or hydraulic motor can bring up to the level of piston type hydraulic pumps or motor, the output liquid of pump Pressure or the output torque ratio traditional blades pump of hydraulic motor or hydraulic motor improve more than 10 times, service life significantly carries High.
