Description
Technical field
The utility model relates to a kind of machine shaft, specifically a kind of with spoke iron every magnetogenerator rotating shaft.
Background technique
Existing machine shaft is generally made up of the rotor iron core that axle and its are fixedly installed, because whole rotor is real cored structure, the quality of rotor is large, and in the rotation process of rotor, axial change in flexibility is large, also there is rotor radiating effect bad simultaneously.Also there is the machine shaft be made up of axle, spoke iron plate in the market, thus decrease the weight of rotor, but stress on the machine shaft cross section of this structure is large, easily causes axle fracture, this motor ventilation poor performance, therefore can not well be applied simultaneously.And machine operation rotor magnetic field of gripping portion unshakable in one's determination can enter machine shaft, thus larger eddy current loss and shaft current can be caused in machine shaft inside, so not only the loss of electric machine can be increased, and shaft current can produce infringement to bearing, cause motor to occur quality problems, greatly reduce the life-span of motor.
Summary of the invention
The purpose of this utility model be to provide a kind of with spoke iron every magnetogenerator rotating shaft, to solve the problem proposed in above-mentioned background technology.
For achieving the above object, the utility model provides following technological scheme:
A kind of with spoke iron every magnetogenerator rotating shaft, comprise the rotating shaft be set in rotor, narrow spoke iron plate and wide spoke iron plate, described rotating shaft is hollow-core construction, rotating shaft is arranged on the axial location of rotor, described narrow spoke iron plate and wide spoke iron plate are distributed in rotating shaft on the surface uniformly along the axis of rotating shaft, be provided with every magnetic lining between adjacent narrow spoke iron plate and wide spoke iron plate, fixed cover is arranged with outside magnetic lining, the stream aerofoil be positioned at outside fixed cover is also provided with between adjacent narrow spoke iron plate and wide spoke iron plate, the end of described wide spoke iron plate is provided with keyway, the side of wide spoke iron plate also offers symmetrical through hole, the side of wide spoke iron plate also offers along rotating shaft radial direction and the groove be communicated with through hole.
As further program of the utility model: described narrow spoke iron plate and wide spoke iron plate are equipped with two pieces or three pieces, and described keyway is provided with one.
Compared with prior art, the beneficial effects of the utility model are: the rotating shaft of the utility model hollow core structure not only own wt alleviates, but also adds the ventilating problem of motor internal, reduce the temperature in motor; The iron plate arranged changes the overall structure of original rotor, alleviates the overall weight of rotor and axle; What arrange can weaken the magnetic flux of rotor iron core in rotating shaft greatly every magnetic lining, reduce the energy ezpenditure caused by eddy current in shaft current and rotating shaft, therefore also reduce the damage probability of rotating shaft, reduce maintenance frequency and the replacement frequency of rotating shaft, reduce the maintenance expenses of equipment; The setting of stream aerofoil improves the inner ventilation of motor, reduces the temperature in motor, extends the life-span of rotating shaft and motor.
Accompanying drawing explanation
Fig. 1 is the schematic diagram every magnetogenerator rotating shaft of band spoke iron.
Fig. 2 is the side view every magnetogenerator rotating shaft of band spoke iron.
In figure: 1-rotating shaft; The wide spoke iron plate of 2-; The narrow spoke iron plate of 3-; 4-flows aerofoil; 5-keyway; 6-is every magnetic lining; 7-fixed cover; 8-rotor; 9-through hole; 10-groove.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technological scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Refer to Fig. 1 ~ 2, in the utility model embodiment, a kind of with spoke iron every magnetogenerator rotating shaft, comprise and be set in the narrow spoke iron plate 3 of rotating shaft 1, three pieces in rotor 8 and three pieces wide spoke iron plates 2, the rotating shaft 1 of hollow-core construction not only own wt alleviates, but also add the ventilating problem of motor internal, reduce the temperature in motor; Rotating shaft 1 is arranged on the axial location of rotor 8, and narrow spoke iron plate 3 and wide spoke iron plate 2 are distributed in rotating shaft 1 on the surface uniformly along the axis of rotating shaft 1, and the iron plate of setting changes the overall structure of original rotor, alleviates the overall weight of rotor and axle; Be provided with every magnetic lining 6 between adjacent narrow spoke iron plate 3 and wide spoke iron plate 2, fixed cover 7 is arranged with outside magnetic lining 6, that the non-magnet material such as stainless steel, copper is made every magnetic lining 6, greatly reduce the magnetic flux of rotor iron core in rotating shaft, reduce the energy ezpenditure caused by the eddy current in shaft current and rotating shaft, therefore also reduce the damage probability of rotating shaft, reduce maintenance frequency and the replacement frequency of rotating shaft, reduce the maintenance expenses of equipment.
The stream aerofoil 4 be positioned at outside fixed cover 7 is also provided with between adjacent narrow spoke iron plate 3 and wide spoke iron plate 2, the end of one of them wide spoke iron plate 2 is provided with keyway 5, the side of wide spoke iron plate 2 also offers symmetrical through hole 9, the side of wide spoke iron plate 2 also offers along rotating shaft 1 radial direction and the groove 10 be communicated with through hole 9, groove 10 is directly connected with air, stream aerofoil 4 and through hole 9, effect between groove 10, improve the inner ventilation of motor, reduce the temperature in motor, extend the life-span of rotating shaft and motor.
To those skilled in the art, obvious the utility model is not limited to the details of above-mentioned one exemplary embodiment, and when not deviating from spirit of the present utility model or essential characteristic, can realize the utility model in other specific forms.Therefore, no matter from which point, all should embodiment be regarded as exemplary, and be nonrestrictive, scope of the present utility model is limited by claims instead of above-mentioned explanation, and all changes be therefore intended in the implication of the equivalency by dropping on claim and scope are included in the utility model.Any reference character in claim should be considered as the claim involved by limiting.
