Abstract
The present invention relates to a liquid machine with variable capacity, particularly to a liquid machine with variable capacity which can be used as a motor and a pump. The present invention is characterized in that the outer surface curve of an inner stator (1) and the inner surface curve of an outer stator (3) are two identical smooth closed curves; the inner stator (1) and the outer stator (3) mutually rotate around the same center of circle at the angle of pi/n; a rotor (2) is a circular ring, and 4 to 100 roller groups are distributed on the rotor (2). Each roller group is composed of an outer roller, an outer roller plug, an inner roller, an inner roller plug and a spring. The motor (pump) has the advantages of novel design, stable work, high efficiency and long service life, and can be used as a motor and a pump.
Description
Technical field
The present invention relates to a kind of fluid varactor machine, particularly a kind of motor of doing can be made two stator couple pumps that pump uses again.
Background technique
Hydraulic transmission is widely used in all trades and professions, oil hydraulic pump (comprising gear pump, vane pump, plunger pump, screw pump) as its cardiac component mainly is to rely on moment work, and the major part major part all is in the sliding friction state, the force unbalance situation appears being subjected to unavoidably, be restricted the working life of bearing, thereby reduce the working life of pump.These deficiencies have influenced the development of hydraulic element.
Summary of the invention
The object of the invention is to provide a kind of pair of stator couple pump, this pump modern design, and stable working, efficient height, life-span are long, can make pump and can make motor again and use.
This pair of stator couple pump, comprise inner stator 1, external stator 3, rotor 2, oil inlet and outlet 4,5,6, plunger group and two side plates compositions, it is characterized in that: the internal surface curve of the outer surface curve of inner stator 1 and external stator 3 is the similar smooth closed curves of two strips, and the similar smooth closed curve of two strips is that frame transition curve, regular polygon add transition curve between elliptic curve, two great circles and two roundlets; Transition curve be constant acceleration curve, etc. deceleration curve, sinusoidal curve add the curve of correction; Inner stator 1 and external stator 3 rotate π/n angle round about mutually and place around the same center of circle, n is a polygonal limit number, and elliptic curve will rotate 90 ° of angles mutually and place; Article two, between smooth closed curve, in passing through any radial zone in the center of circle, outer plunger is stretched out simultaneously or is compressed in guaranteeing; Rotor 2 is annulus, uniform 4～100 group of rollers on it; Group of rollers is made up of spring 9, inside and outside two plungers 8 and inside and outside two rollers 7, also can be that two blades and spring are formed, the cross section of plunger 8 be square, and an end has spring groove, one end has the spill circular arc, and the radius of its circular arc is more than or equal to the radius of roller 7; Can also adorn 1～2 group of two stator couple pump within the inner stator 1 or outside the external stator 3, form twin-stage and multistage pair of stator pumps, when rotor 2 rotates, by inner stator 1, interior roller, inner plunger, pump in the molten long-pending composition that the inward flange of rotor 2 and biside plate surround, by pump in inner plunger and outer plunger, rotor 2 slideway bi-side and the volumetric composition that biside plate surrounded, the outer pump of the volumetric composition that outward edge and biside plate surrounded that external stator 3, outer roller, outer plunger, rotor 2 are arranged, can inhale and press oil, three pumps are simultaneously in running order.
Description of drawings

The internal surface curve of the outer surface curve of Fig. 2 inner stator and external stator is the smooth two stator couple pump structure schematic representation of equilateral triangle.
In Fig. 1,1. inner stator, 2. rotor, 3. external stator, 4. in the pump oil inlet and outlet, 5. in the pump oil inlet and outlet, 6. outer pump oil inlet and outlet, 7. roller, 8. plunger, 9. spring.
Embodiment
Accompanying drawing 1 is embodiment's (see figure 1) disclosed by the invention.Inner stator 1 is two identical elliptic curves with external stator 3, and rotate 90 ° of angles round about around the center of circle and place, inner stator 1 and external stator 3 are fastenedly connected and become one, rotor 2 is an annulus, be arranged between inner stator 1 and the external stator 3, be evenly distributed 6 group of rollers on the rotor 2, each group of rollers comprises two rollers 7, two opposite directions arrange that two is respectively the square plunger 8 and the spring 9 of spill arc surface and spring eye, when center of circle when rotation of rotor 2 round oneself, by inner stator 1, interior roller 7, inner plunger 8, the volume that rotor 2 and biside plate are formed (can be considered interior pump), by inner plunger 8, outer plunger 8, rotor 2 and the volume (can be considered middle pump) that biside plate surrounded, by external stator 3, outer roller 7, outer plunger 8, rotor 2 and the volume (can be considered outer pump) that biside plate surrounded, all in the variation of generating period, along with rotor rotation can be carried out oil suction and be pressed oil.In, domestic and abroad pump inhales simultaneously and presses oil, makes the unification of three pumps, each parts equilibrium of forces at this moment, three pumps drive output shaft simultaneously.Can be made into three or three smooth two stator couple pumps that close the envelope curve of above regular polygon equally, Fig. 2 is the schematic diagram of the two stator couple pumps of triangle.
