Abstract
The invention relates to a rotor of an alternating-current asynchronous motor, which comprises a rotor iron core sleeved on a shaft. A rotor clamping ring is respectively arranged at two ends of the rotor iron core; the rotor iron core consists of a plurality of rotor punching sheets by superposition; the edges of the punching sheets are provided with a plurality of sheet-punching grooves; one end of each sheet-punching groove points at the centers of the rotor punching sheets; and the other end of each sheet-punching groove is open. The alternating-current asynchronous motor is characterized in that the outside diameter of the rotor punching sheets is equal to that of the rotor iron core. A conducting rod is arranged in the sheet-punching grooves; an end ring is connected to the inner side at the end part of the conducting rod; the end part of the shaft is provided with a key groove; and an arc key for fixing the rotor iron core is arranged in the key groove. The invention has the advantages of simple structure, safety and obvious effect. Under the conditions of ensuring the safety and the reliability of the motor and keeping the electromagnetic design unchangeable, the processing time and the sheet-punching material are saved by changing the design of the punching sheets, thereby improving production efficiency and eliminating incipient faults in use.
Description
Technical field
The present invention 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 through 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, and the punching that car falls directly slatterns, and adds man-hour iron filings if cleaning does not totally get 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 the hidden danger in the motor use.
Summary of the invention
The objective of the invention is to overcome the deficiency that exists in the prior art, a kind of rotor of AC induction motor of saving the Vehicle Processing workload and avoiding the waste of material is provided.
According to technical scheme provided by the invention, the rotor of said 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; Said rotor core is formed by stacking 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; Characteristic is: the external diameter of said rotor punching equals the external diameter of rotor core.
In said punching groove, conducting rod is set, is connected with end ring in the inboard of conducting rod end.
The end of said axle is provided with keyway, in keyway, is provided with the arc key that is used for fixing rotor core.
During installation: at first the rotor punching with some finishes with the punching out of jet-bedding edger, compresses the back through hydraulic pressure and forms rotor core, and the rotor core two ends clamp spot welding through rotor pressing ring; Conducting rod injects in the rotor core successively; And end ring is welded on the below of conducting rod with the HlAgCu80-5 silver-copper brazing alloy, and rotor core is heated to 220 ℃ and keep constant temperature 3h, be inserted in axle then; And fill in the keyway on the axle with the arc key, fixed rotor is unshakable in one's determination.
Simple in structure, the safety of the present invention, action effect is obvious; Do not change Electromagnetic Design situation under, under the condition that guarantees motor safety property and reliability, change through design to punching, reach saving process time, thereby the requirement that the punching material is enhanced productivity and eliminated use hidden danger.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Fig. 2 is the sketch map of rotor punching of the present invention.
Embodiment
Below in conjunction with concrete accompanying drawing the present invention is described further.
Like 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 present invention includes the rotor core 4 that is enclosed within on the axle 6, be provided with rotor pressing ring 3 at the two ends of rotor core 4; Said rotor core 4 is formed by stacking 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 said 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 said axle 6 is provided with keyway, in keyway, is provided with the arc key 5 that is used for fixing rotor core 4.
Operation principle of the present invention: the external diameter of rotor punching of the present invention 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 invention is following: after at first the rotor punching of some being finished with the punching out of jet-bedding edger; Compress the back through hydraulic pressure and form rotor core 4, rotor core 4 two ends clamp spot welding through rotor pressing ring 3, and conducting rod 2 injects in the rotor core 4 successively; And with the HlAgCu80-5 silver-copper brazing alloy end ring 1 is welded on the below of conducting rod 2; 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 unshakable in one's determination 4 with arc key 5.
