The sheet grooves are provided with conductive rods, and end parts of the conductive rods are connected with end rings on the inner sides. End parts of the shaft are provided with key grooves, and arced grooves for fixing the rotor core are arranged in the key grooves. The rotor of the utility model has a simple and safe structure, and has obvious action effect; under a condition of un-changing electromagnetic design and ensuring safety and reliability of the motor, it is possible to save machining time and sheet material so as to improve production efficiency and eliminate hidden danger by changing sheet design.
Description
Technical field
The utility model relates to a kind of rotor, especially a kind of rotor that is used for threephase asynchronous.
Background technology
All the time, many electrical machinery plants are in making the motor process in the electromechanics trade, and engineering department requires to process the concentricity that guarantees the rotor cylindrical by the rotor cylindrical, and general allowance is about monolateral 0.3mm.The early stage punching of splitting die punching out even several millimeters the processing capacity (air gap is by processing) of using.The Vehicle Processing of rotor cylindrical to guaranteeing concentricity no doubt is, but Vehicle Processing is not only wasted time and energy, the punching that car falls directly slatterns, and add man-hour iron filings if cleaning does not totally enter between the punching in the air duct, iron filings fly out sometimes when rotor high-speed rotates, splash and to cause insulation damage in various degree on the stator coil, when serious even cause and blow out, directly influence the useful life of motor.Therefore if having a kind of way guarantee rotor not turning can satisfy certain concentricity again, can use manpower and material resources sparingly like this and can eliminate hidden danger in the motor use.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of rotor of AC induction motor of saving the Vehicle Processing workload and avoiding the waste of material is provided.
According to the technical scheme that the utility model provides, the rotor of described AC induction motor comprises the rotor core that is enclosed within on the axle, is provided with rotor pressing ring at the two ends of rotor core; Described rotor core is formed by stacking by some rotor punchings, is provided with some road punching grooves at the edge of rotor punching, and an end of punching groove points to the center of rotor punching, and the other end of punching groove is opening-like; Feature is: the external diameter of described rotor punching equals the external diameter of rotor core.
In described punching groove, conducting rod is set, is connected with end ring in the inboard of conducting rod end.
The end of described axle is provided with keyway, is provided with the arc key that is used for fixing rotor core in keyway.
Simple in structure, the safety of the utility model, action effect is obvious; Do not change Electromagnetic Design situation under, under the condition that guarantees motor safety and reliability, change by design to punching, reach and save process time, thereby the requirement that the punching material is enhanced productivity and eliminated use hidden danger.

Embodiment
The utility model is described in further detail below in conjunction with concrete accompanying drawing.
As Fig. 1 ~ shown in Figure 2: the rotor of AC induction motor comprises end ring 1, conducting rod 2, rotor pressing ring 3, rotor core 4, arc key 5, axle 6, punching groove 7 etc.
The utility model comprises the rotor core 4 that is enclosed within on the axle 6, is provided with rotor pressing ring 3 at the two ends of rotor core 4; Described rotor core 4 is formed by stacking by some rotor punchings, is provided with some road punching grooves 7 at the edge of rotor punching, and an end of punching groove 7 points to the center of rotor punching, and the other end of punching groove 7 is opening-like; The external diameter of described rotor punching equals the external diameter of rotor core 4;
Conducting rod 2 is set in punching groove 7, is connected with end ring 1 in the inboard of conducting rod 2 ends;
The end of described axle 6 is provided with keyway, is provided with the arc key 5 that is used for fixing rotor core 4 in keyway.
Operation principle of the present utility model: the external diameter of rotor punching of the present utility model is the external diameter of rotor core 4, and the high size of the notch of punching groove 7 is no longer reserved the allowance of 0.3mm, and promptly rotor need not car rotor cylindrical after improving.
Installation process of the present utility model is as follows: after at first the rotor punching of some being finished with the punching out of jet-bedding edger, compress the back by hydraulic pressure and form rotor core 4, rotor core 4 two ends clamp spot welding by rotor pressing ring 3, conducting rod 2 injects in the rotor core 4 successively, and end ring 1 is welded on the below of conducting rod 2 with the HlAgCu80-5 silver-copper brazing alloy, pass through hot cover process, rotor core 7 is heated to 220 ℃ and keep constant temperature 3h, be inserted in axle 6 then, and fill in the keyway of axle on 6 fixed rotor iron core 4 with arc key 5.
