The mechanical energy conversion system includes a transmission shaft, a front bearing and a back bearing. The hydraulic energy conversion system includes a cylinder body, an inclined disk, a plunger and the like. The electric energy conversion system includes a rotor coil, a stator iron core, an excitation winding, a lead terminal and the like. The stator iron core and the excitation winding of the stator iron core are fixed in a large inner cavity of a shell. The adjusting cylinder is fixed in asmall inner cavity of the shell. The transmission shaft and the cylinder body are connected through a spline to rotate synchronously. With the action of the inclined disk, the plunger reciprocates along the axis to suck in or output e hydraulic oil. During concrete work, the lead terminal is externally connected with direct current, discharge capacity and hydraulic flow direction are adjusted through an adjusting bolt, and mutual transformation between mechanical energy, hydraulic energy and electrical energy is achieved. The inclined disk variable type electromechanical fluid coupler has theadvantages of being compact in structure, high in conversion efficiency, small in pressure loss and the like, and the application demand and industrialization prospect are wide because the adjustableadaptability of the discharge capacity is enhanced.

Description

technical field [0001] The invention belongs to the field of electromechanical hydraulic power transmission and conversion, and relates to a swash plate variable electromechanical hydraulic coupler for DC stator excitation. 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 coordination reduce reliability, and there is a risk of leakage; the efficiency is also very low; and only hydraulic energy can be output, mechanical energy and energy conversion cannot be output.

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 coordination reduce reliability and risk of leakage; efficiency is also very low; and only hydraulic energy can be output, 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 purchasing spare tools, it is often necessary to purchase multiple types of tools. The cost of transportation and procurement has been greatly increased. For this reason, it is urgent to propose a mechanical structure design that can realize the conversion and flexible adjustment of various energies, and work stably and with low noise.
