Problems solved by technology

[0003] 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. They are used in medium and low-pressure hydraulic systems, and 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.

Abstract

The invention discloses a difunctional vane type hydraulic transformer controlled by a motor, comprising a housing, a rotation axis, a left end cap, a port plate, stators, rotors, a right end cap, a gear, a vane, a motor, etc. The invention is characterized in that the centers of the rotor and the center of the stator are fixed and coincident, and the vane is arranged along the radial direction of the rotor; one rotor is connected with the left half axis of the rotation axis in a matching mode by a spline, and the other rotor is connected with the right half axis of the rotation axis in a matching mode by a spline; the outer ring of one stator is made into a gear form by taking the major radius arc center as the center and ranging within 150 degrees, and one stator and the gear form a gear transmission pair; the gear is installed on the output axis of the motor, the motor is arranged on the housing, and the port plate is arranged on the rotation axis and is tightly pressed on the leftside surface and the right side surface of the rotor; and the left end cap and the right end cap are fixed on the housing via bolts. The invention has the beneficial effect that the invention can adjust the voltage of a constant-voltage network system to any value within induced pressure variation range in the way of no throttle loss, and can be used in medium-voltage hydraulic systems and high-voltage hydraulic systems.

Description

(1) Technical field [0001] The invention relates to a hydraulic transformer, in particular to a motor-controlled double-action 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] 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. They are used in medium and low-pressure hydrauli...
