The present invention is squirrel cage asynchronous motor when converting electrical energy into mechanical energy, and now lead terminal U, V, W is external
Three-phase alternating voltage, stator winding 30 and stator core 29 produce the electromagnetic field of rotation, and the cutting magnetic line of cage modle conductor 9 produces sense
Raw voltage, and induced current is formed in cage modle conductor 9, so as to produce electromagnetic torque driving cage modle conductor 9, mouse cage caliper 8 and
The speed discrepancy of the synchronous axial system of cylinder body 10, circular electric-magnetic field rotary speed and cage modle conductor 9 is bigger, and electromagnetic torque is bigger.Cylinder body 10 leads to again
The spline driving external output mechanical energy of the synchronous axial system of power transmission shaft 37 is crossed, realizes electric energy to mechanical transformation of energy.Now plunger-piston shoes
Component, return plate 19, steel ball 16, spring base 25, a set of cups 26, spring 13 are with the synchronous axial system of cylinder body 10.In the course of work, swash plate 18
Top surface it is preferably vertical with the axis of power transmission shaft 37, hydraulic displacement now of the invention is zero, otherwise must be by the upper He of oil circuit 32
The lower short circuit of oil circuit 6.
It is same with the function phase of motor-plunger pump combined system when the present invention converts electrical energy into hydraulic energy, now lead
The external three-phase alternating voltage of terminal U, V, W, stator winding 30 and stator core 29 produce the electromagnetic field of rotation, and cage modle conductor 9 is cut
Cut the magnetic line of force and produce induced potential, and induced current is formed in cage modle conductor 9, so as to produce electromagnetic torque driving cage modle conductor
9th, mouse cage caliper 8 and the synchronous axial system of cylinder body 10, and then drive plunger 11, piston shoes 20, return plate 19 etc. to rotate, in the top surface of swash plate 18
Under thrust and the elastic force collective effect of spring 13, plunger 11 makees axially reciprocating while being circumferentially rotated with cylinder body 10, works as plunger
11 when being moved right, and low pressure oil is constantly entered by upper oil circuit 32 (or lower oil circuit 6), by the oil-distribution port on valve plate 7, is entered
Pump chamber；When plunger 11 is to left movement, oil pressure raises in pump chamber, and hydraulic oil is constantly by pump chamber by the flow window on valve plate 7
Mouth, lower oil circuit 6 (or upper oil circuit 32) externally export, and realize electric energy to hydraulic pressure transformation of energy.
When the present invention is by hydraulic energy transfer mechanical energy, as hydraulic motor, now hydraulic oil is constantly by upper oil circuit 32 (under or
Oil circuit 6) enter, by the oil-distribution port on valve plate 7, into pump chamber, promote plunger 11 to move to right, piston shoes 20 are along the table of swash plate 18
Face is slided and drives cylinder body 10 to rotate, and when plunger 11 turns to the another half cycle of piston shoes 20, plunger 11 is moved to the left, in pump chamber
Hydraulic oil is constantly flowed out by corresponding oil-distribution port on valve plate 7 by lower oil circuit 6 (or upper oil circuit 32).Cylinder body 10 rotates, then
The external output mechanical energy of the synchronous axial system of power transmission shaft 37 is driven by spline, realizes hydraulic energy to mechanical transformation of energy.
When mechanical energy is converted into hydraulic energy by the present invention, as hydraulic pump, now external impetus driving power transmission shaft 37 rotate,
Again by synchronous axial systems such as spline drivig cylinder 10, plunger 11, piston shoes 20, in the thrust of the upper surface of swash plate 18 and the bullet of spring 13
Power effect lower plunger 11 moves back and forth, and when plunger 11 moves right, low pressure oil is constantly entered by upper oil circuit 32 (or lower oil circuit 6)
Enter, by the oil-distribution port on valve plate 7, into pump chamber；When plunger 11 is to left movement, oil pressure raises in pump chamber, hydraulic oil
Constantly externally exported by the oil-distribution port on valve plate 7, lower oil circuit 6 (or upper oil circuit 32) by pump chamber, realize mechanical energy to liquid
Press transformation of energy.
The present invention realizes conversion of the electric energy to mechanical energy and hydraulic energy, the mutual conversion of hydraulic energy and mechanical energy, electric energy
Hydraulic energy, electric energy and hydraulic energy are converted into mechanical energy simultaneously while is converted into mechanical energy, and discharge capacity is variable, compact-sized, energy
Conversion ratio is high, and application demand and industrialization prospect are wide.
It should be appreciated that for those of ordinary skills, can according to the above description be improved or converted,
And all these modifications and variations should all belong to the protection domain of appended claims of the present invention.
