Direct current quantitative stator permanent magnetic type integrated power device

Abstract

The invention discloses a direct current quantitative stator permanent magnetic type integrated power device and relates to the technical field of energy conversion. The direct current quantitative stator permanent magnetic type integrated power device comprises a supporting system and further comprises a mechanical energy conversion system, a hydraulic energy conversion system and an electric energy conversion system which are connected with the supporting system. The mechanical energy conversion system comprises a transmission shaft, a front bearing and a rear bearing, and the power end / output end of the transmission shaft penetrates out of a circular hole of a shell; the hydraulic energy conversion system comprises a swash plate, a retainer plate, a cylinder body, a plunger, a cylindersleeve, a slipper, a pressure spring and a spherical spring seat; and the electric energy conversion system comprises an elastic body, an electric brush, a commutator, a rotor coil and two permanent magnets with the arc-shaped inner surfaces. The direct current quantitative stator permanent magnetic type integrated power device has the beneficial effects that two-by-two mutual conversion among mechanical energy, hydraulic energy and electric energy is achieved, the overall design thought is adopted, coupling of machinery, electricity and hydraulics and mutual conversion of the corresponding energy are ingeniously achieved, mechanical connection of a motor and a pump is omitted, the structure is compact, the energy conversion rate is high, and the size is small.

Description

technical field [0001] The invention relates to the technical field of energy conversion, in particular to a DC quantitative stator permanent magnet integrated power device. Background technique [0002] There are three main hydraulic power sources, traditional motor-pump set, shielded motor pump and electro-hydraulic pump. The former two adopt the method of connecting the motor and the liquid pump by the transmission shaft, which will bring many disadvantages: the noise and vibration caused by the non-concentricity of the coupling; the axial arrangement makes its volume and quality Larger; multiple connections and fits reduce reliability, risk of leakage; and low efficiency. Moreover, only hydraulic energy can be output, and mechanical energy and energy conversion cannot be output. [0003] In the prior art, it is common to use one or two tools for the conversion between different forms of main energy. In different working conditions, long-distance outdoor operations or p...

Problems solved by technology

The former two adopt the method of connecting the motor and the liquid pump by the transmission shaft, which will bring many disadvantages: the noise and vibration caused by the non-concentricity of the coupling; the axial arrangement makes its volume and quality Larger; multiple connections and fits reduce reliability, risk of leakage; also low efficiency

And it can only output hydraulic energy, not mechanical energy and energy conversion
