Abstract
The invention relates to a rotor lead structure of a wound type electromotor, which comprises a rotor coil and a slip ring arranged on a shaft, wherein one end of a rotor lead is connected with the rotor coil, and the other end of the rotor lead is connected with the slip ring; the shaft is provided with an axial groove, and the rotor lead is positioned in the groove; and a sleeve is tightly matched with the shaft at the groove. In the invention, the shaft is provided with the groove so that the rotor lead passes through a shaft surface, thus achieving the purpose of double shaft extension so as to break through the traditional technology that the rotor lead passes through a bore hole in the shaft. The rotor lead structure has simple structure, does not change the original motor structure and guarantees electromotor performance.
Description
Technical field
The present invention relates to the high-tension winding threephase asynchronous, be specifically related to a kind of rotor leading wire structure of winding motor.
Background technology
Because the high capacity motor capacity is big, starting current is bigger to the impact of electrical network, and because of being with heavy duty, the load request motor provides bigger starting torque again, obvious common squirrel-cage motor is difficult to satisfy above-mentioned two requirements simultaneously, and wire wound asynchronous motor just demonstrates clear superiority.For the operating mode of large and medium motor band heavy-load start, generally all adopt wire wound asynchronous motor.The characteristics of wound-rotor motor are can insert external resistor in the rotor, when normally moving, and three phase winding short circuits; During starting,, can insert starting resistance in the rotor, improve starting torque for reducing starting current.
Common wound-rotor motor is generally single shaft and stretches, and rotor leading wire is received on the slip ring by drawing in boring on the axle.When stretching for the customer requirement twin shaft, the motor shaft of slip ring end need be made second shaft extension, therefore can't adopt existing rotor leading wire structure, is difficult to satisfy client's instructions for use, and this also is a key factor of a lot of motor of restriction producer development winding motor.
Summary of the invention
The present invention is directed to the problems referred to above, a kind of rotor leading wire structure of winding motor is provided, this structure had both guaranteed the performance of motor each side, had satisfied the requirement that twin shaft is stretched again.
Technical scheme of the present invention is as follows: a kind of rotor leading wire structure of winding motor, comprise the rotor coil and the slip ring that are installed on the axle, one end of rotor leading wire is connected with rotor coil, its other end is connected with slip ring, offer axial groove on the described axle, described rotor leading wire is positioned at described groove, and the described axle at described groove place tightens and is combined with sleeve.
Its further technical scheme is: described groove has three, is distributed on the described axle.
Described quill shaft is provided with cushion block to the described groove of both sides, and described cushion block is fixed on the described axle by no latitude band.
Be banded with described no latitude band on the described axle between described sleeve and the described slip ring.
Useful technique effect of the present invention is: the present invention is by offering groove on axle, makes rotor leading wire walk the axle surface, reach the purpose that twin shaft is stretched, thereby broken through go between the away traditional handicraft of an internal drilling of conventional rotors.The present invention is simple in structure, does not change original electric machine structure, has guaranteed motor properties.
Description of drawings
Fig. 1 is a structure assembling schematic diagram of the present invention.
Fig. 2 is the K-K cutaway view among Fig. 1.
Embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present invention is described further.
Among Fig. 1, Fig. 2, comprise rotor coil 1, rotor leading wire 2, cushion block 3, axle 4, bearing assembly parts 5, sleeve 6, hex bolts 7, packing ring 8, slip ring 9, back-up ring 10, no latitude band 11, silver soldering point 12, groove 13 etc.
As shown in Figure 1, the present invention is a kind of rotor leading wire structure of winding motor, comprises the rotor coil 1 and the slip ring 9 that are installed on the axle 4, and an end of rotor leading wire 2 is connected with rotor coil 1, and its other end is connected with slip ring 9.Improvements of the present invention are to offer axial groove 13 on the axle 4 at bearing assembly parts 5 places, and rotor leading wire 2 is arranged in the groove 13, and the axle 4 at groove 13 places tightens and is combined with sleeve 6, and bearing assembly parts 5 are installed on the sleeve 6.
As shown in Figure 2, groove 13 has three, is distributed on the axle 4, and three roots rotors lead-in wire 2 lays respectively in three grooves 13.
Referring to Fig. 1, the groove 13 of sleeve 6 axial both sides is provided with cushion block 3, and cushion block 3 is fixed on the axle 4 by no latitude band 11.The effect of cushion block 3 is rotor leading wires 2 that protection exposes, and prevents rotor leading wire 2 and axle 4 wearing and tearing.In like manner, between sleeve 6 and the slip ring 9 the axle 4 on also colligation have or not latitude band 11.
Installation process of the present invention is as follows: at first sleeve 6 is heated to 220 ℃, and insulation 1h, sleeve 6 is inserted on the axle 4, treat sleeve 6 natural cooling, bearing assembly parts 5 are inserted on sleeve 6 outer surfaces; Again slip ring 9 is heated to 220 ℃, and insulation 2h, slip ring 9 is inserted on the axle 4, and fixing with back-up ring 10, treat slip ring 9 natural cooling; Again rotor leading wire 2 is penetrated the groove 13 on the axle 4, rotor leading wire 2 one ends link together with slip ring 9 by hex bolts 7, packing ring 8, the other end welds together by silver soldering point 12 and rotor coil 1, then cushion block 3 is filled up on rotor leading wire 2, use no latitude band 11 colligations on cushion block 3 surfaces at last, the thickness of no latitude band 11 is not less than 5mm.
The present invention is by offering groove 13 on axle 4, make rotor leading wire 2 walk axle 4 surfaces, reach the purpose that twin shaft is stretched, thereby broken through go between the away traditional handicraft of an internal drilling of conventional rotors.The present invention is simple in structure, does not change original electric machine structure, has guaranteed motor properties.
Above-described only is preferred implementation of the present invention, the invention is not restricted to above embodiment.Be appreciated that other improvement and variation that those skilled in the art directly derive or associate under the prerequisite that does not break away from spirit of the present invention and design, all should think to be included within protection scope of the present invention.
