Description
Technical field
The utility model relates to a kind of rotor, and especially a kind of AC induction motor rotor of not turning, belongs to the technical field of AC induction motor rotor.
Background technology
All the time, in electromechanics trade, many electrical machinery plants are in making motor process, and engineering department requires to process by rotor outer circle the concentricity ensureing rotor outer circle, and general allowance is monolateral about 0.3mm.The punching of early application splitting die punching even leaves the processing capacity of several millimeters, and air gap processes by car rotor outer circle completely.Rotor outer circle Vehicle Processing to guarantee concentricity is no doubt, but Vehicle Processing is not only wasted time and energy, the punching that car falls directly slatterns, if and add man-hour iron filings cleaning only do not remain in the air duct of rotor core, when rotor high-speed rotates, iron filings fly out, splash on stator coil and can cause insulation damage in various degree, even cause time serious and blow out, directly affect security performance and the useful life of motor.And rotor turning can destroy the insulating barrier of punching sheet surface coating simultaneously, strengthen iron loss thus the efficiency value of reduction motor.If therefore have a kind of way ensure rotor not turning can meet certain concentricity again, can use manpower and material resources sparingly like this and the potential safety hazard in motor use procedure can be eliminated.
Summary of the invention
The purpose of this utility model overcomes the deficiencies in the prior art, and provide a kind of AC induction motor rotor of not turning, its compact conformation, can save labor content, cut down finished cost, adaptability is good, safe and reliable.
According to the technical scheme that the utility model provides, the AC induction motor rotor of described not turning, comprise and compress by the rotor punching of some employing jet-bedding edgers punching the rotor core formed, described rotor core is enclosed within armature spindle, the edge, outer ring of rotor punching arranges some punching grooves, be equipped with conducting rod in each punching groove in rotor core, the end of conducting rod is connected by end ring.
The both sides of described rotor core arrange the rotor pressing ring be used for described rotor core internal rotor punching clamping; Armature spindle arranges keyway, the arc key being used for fixed rotor iron core is set in described keyway.
Described rotor punching is circular, and the center of rotor punching arranges centre bore, and the opening-like and notch that is punching groove of the notch of punching groove is positioned at the edge of rotor punching outer ring, and the external diameter of the rotor punching of punching is identical all the time with the external diameter of rotor core.
Advantage of the present utility model: adopt the rotor punching of jet-bedding edger punching to compress the rotor core formed, the external diameter of rotor punching is identical with the external diameter of the rotor core finally formed, do not need again to carry out machined into rotor punching, reach and save machining period, punching material thus the requirement of enhancing productivity eliminate potential safety hazard, ensure motor safety and reliability.

Embodiment
Below in conjunction with concrete drawings and Examples, the utility model is described in further detail.
As shown in Figure 1: in order to can labor content be saved, cut down finished cost, the utility model comprises and compresses by the rotor punching 7 of some employing jet-bedding edgers punching the rotor core 4 formed, described rotor core 4 is enclosed within armature spindle 6, the edge, outer ring of rotor punching 7 arranges some punching grooves 10, be equipped with conducting rod 2 in each punching groove 10 in rotor core 4, the end of conducting rod 2 is connected by end ring 1.
Particularly, rotor punching 7 adopts the punching of jet-bedding edger to form, and multiple rotor punching 7 forms rotor core 4 after aiming at and compressing, and rotor punching 7 compression forms rotor core 4 and is consistent with the external diameter of required rotor core 4, does not namely need the operation of turning.Rotor core 4 is enclosed within armature spindle 6, rotor core 4 and armature spindle 6 are in coaxial distribution, rotor punching 7 in rotor core 4 is in identical placement, the punching groove 10 of rotor core 4 internal rotor punching 7 aligns, to form multiple punching groove in rotor core 4, conducting rod 2 is placed in each punching groove 10, all rotor punchings 7 of rotor core 4 are passed at the two ends of conducting rod 2, the two ends of conducting rod 2 are positioned at outside rotor core 4, the end of each conducting rod 2 is all connected by end ring 1, namely linked into an integrated entity by end ring 1, conducting rod 2 and armature spindle 6 are in parallel distribution.
Further, the both sides of described rotor core 4 arrange the rotor pressing ring 3 described rotor core 4 internal rotor punching 7 clamped; Armature spindle 6 arranges keyway, the arc key 5 being used for fixed rotor iron core 4 is set in described keyway.
As shown in Figures 2 and 3, described rotor punching 7 is in circular, the center of rotor punching 7 arranges centre bore 9, and the opening-like and notch that is punching groove 10 of the notch of punching groove 10 is positioned at the edge of rotor punching 7 outer ring, and the external diameter of the rotor punching 7 of punching is identical all the time with the external diameter of rotor core 4.
In the utility model embodiment, centre bore 9 aperture of rotor punching 7 and the external diameter of armature spindle 6 match, and can be enclosed within armature spindle 6 to make the rotor core 4 formed.The center of rotor punching 7 is pointed in one end of punching groove 10, the other end of punching groove 10 is opening-like, the external diameter of rotor punching 7 is identical with the external diameter of rotor core 4 all the time, the notch height of punching groove 10 is h, the allowance of the no longer reserved 0.3mm or larger of notch of punching groove 10, does not namely need to pass through one machined into again.
