Double-acting blade-type hydraulic transformer

Abstract

The invention relates to a double-acting blade-type hydraulic transformer which comprises a shell, a rotating shaft, a left end cover, stators, rotors, a right end cover, blades, a variable cylinder, a thrust plate and the like. The invention is characterized in that the centers of the rotors and the stators are fixed and coincident; the blades are arranged in the radial direction of the rotor; one rotor is fit-connected with a left half shaft of the rotating shaft through a spline, and the other rotor is fit-connected with a right half shaft of the rotating shaft through a spline; and the thrust plate is installed on the rotating shaft and is tightly pressed on the left and right lateral faces of the stator; the variable cylinder comprises a variable piston, a variable rod, a variable cylinder body and the like, wherein the variable cylinder body is fixed on the shell by bolts; the spherical head end of the variable rod is connected with the groove of the variable piston, and the other end of the variable rod is fixed on the external surface of the center line of the long radius arc of one stator; the groove of the variable piston is made into arc or involute shape; the left and right end covers are fixed on the shell by bolts.

Description

(1) Technical field [0001] The invention relates to a hydraulic transformer, in particular to a double-acting vane hydraulic transformer, which belongs to the mechanical field. (2) Background technology [0002] A hydraulic transformer is a hydraulic component that realizes pressure conversion in hydraulic transmission. The hydraulic transformer can efficiently convert the input hydraulic energy under a given pressure into the output hydraulic energy under another pressure. Using it can realize the independent control of multiple loads in the constant pressure network, and also make the energy reverse flow , not only can drive linear loads without throttling loss, but also can drive rotary loads. [0003] The existing hydraulic transformers are basically plunger-type structures, with high working pressure above 20Mpa and large flow range. They are generally used in high-pressure and large-flow hydraulic systems, and in medium and low-pressure hydraulic systems, the efficien...

Problems solved by technology

[0003] The existing hydraulic transformers are basically plunger-type structures, with high working pressure above 20Mpa and large flow range. They are generally used in high-pressure and large-flow hydraulic systems, and in medium and low-pressure hydraulic systems, the efficiency is very low. , and the plunger hydraulic transformer has a complex structure, high processing precision, is sensitive to oil pollution, requires high oil filtration precision, and is expensive, so the application range of hydraulic transformers is greatly limited.
