Abstract
The utility model relates to an inner rotation ring air-cooling motor rotor structure. The rotation ring air-cooling motor rotor structure comprises a rotor iron core formed by axial overlapping of a plurality of rotor punched plates, and is characterized in that a plurality of air vents are evenly arranged in the rotor punched plates, and every two adjacent rotor punched plates rotate oppositely and shift in a staggered mode so that the air vents formed by overlapping of rotor punched plates form a spiral ventilation passage of the rotor iron core. According to the inner rotation ring air-cooling motor rotor structure, the air passes through the spiral ventilation passage to thoroughly cool a motor rotor, the cooling effect is good, and therefore a motor is prevented from being burned out.
Description
Technical field
The utility model relates to a kind of rotor, particularly a kind of inward turning ring ventilated machine rotor structure.
Background technology
Rotor produces great amount of heat in rotary work process continuously, can't in time distribute.Because motor is easy to burn out because of rotor is overheated, so be necessary rotor is cooled off.The mode of cooling generally adopts inner-cooled, and promptly to the rotor cooling of ventilating, the ventilation speed of existing rotor is too fast, and inhomogeneous cooling is spared, and cooling effect is relatively poor.Therefore, how addressing the above problem is the object of the utility model research.
Summary of the invention
In view of the deficiency of prior art, the purpose of the utility model is to provide a kind of inward turning ring ventilated machine rotor structure of good cooling results.
To achieve these goals; The technical scheme of the utility model is: a kind of inward turning ring ventilated machine rotor structure; Comprise by the multi-disc rotor punching rotor core that is formed by stacking vertically; Evenly offer several ventilation holes on the said rotor punching, two adjacent rotor punchings rotate relatively and offset so that the ventilation hole of each sheet rotor punching after superimposed forms the spiral air duct of rotor core.
Further, the middle part of said rotor punching offers the through hole that matches with armature spindle.
Further, the outer rim of said rotor punching evenly offers the sliver mouth, the sliver groove of the sliver interruption-forming rotor core after each sheet rotor punching is range upon range of.
Further, said rotor punching is a silicon steel sheet.
Compared with prior art, the utlity model has following advantage: this inward turning ring ventilated machine rotor structure help air through spiral air duct so that rotor is cooled off fully, good cooling results avoids motor to be burnt out.
Description of drawings
Fig. 1 is the organigram of the utility model embodiment rotor punching.
Among the figure: 1-rotor punching, 1-1-ventilation hole, 1-2-through hole, 1-3-sliver mouth.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is done further elaboration.
With reference to figure 1; A kind of inward turning ring ventilated machine rotor structure; Comprise by multi-disc rotor punching 1 rotor core that is formed by stacking vertically; Evenly offer three ventilation hole 1-1 on the said rotor punching 1, two adjacent rotor punchings 1 trace rotation relatively offset so that each sheet rotor punching 1 ventilation hole 1-1 after superimposed forms 3 spiral air ducts of rotor core, and the angle of trace rotation is as the criterion with each ventilation hole 1-1 smooth connection.
In the present embodiment, the outer rim of said rotor punching 1 evenly offers 24 sliver mouth 1-3, and the sliver mouth 1-3 after each sheet rotor punching 1 is range upon range of forms 24 sliver grooves of rotor core.
In the present embodiment, said rotor punching 1 adopts the silicon steel sheet that iron loss is low and magnetic is high, but is not limited to this, and rotor punching 1 can also adopt the steel disc of other types certainly.
Need to prove that especially the number of said ventilation hole 1-1 is not limited to three, can also be two, four or five etc.; The number of said sliver mouth 1-3 also is not limited to 24, can increase and decrease number according to actual needs.
The above is merely the preferred embodiment of the utility model, and all equalizations of being done according to the utility model claim change and modify, and all should belong to the covering scope of the utility model.
