Abstract
The utility model belongs to machine field and provides a kind of damping rotor or anti-electric anti-corrosion structure, comprises rotor core, described rotor core is bonded with some magnetic shoes, and press-in rotating shaft in described rotor core, described rotating shaft is provided with one deck separator.Described separator is non-conductive and has rubber or the plastics of cushioning effect.The beneficial effect that the utility model reaches is: between rotating shaft and rotor core, add one deck non-conductive and have the separator of cushioning effect to reduce induced voltage between rotor and cushioning effect, effectively can prevent bearing electrostatic from corroding, improve the useful life of motor bearings and improve motor noise.
Description
Technical field
The utility model relates to a kind of rotor, and particularly a kind of damping rotor or anti-electric anti-corrosion structure, belong to machine field.
Background technology
The existing general rotating shaft of direct current machine industry rotor directly contacts with rotor core.Direct contact then can cause the bearing electrostatic pressure that in rotating shaft, one is suppressed in appearance itself and rotating shaft because electrostatic induction voltage rising inconsistent, finally causes the generation of noise.Therefore be necessary to design a kind of device reducing induced voltage on machine shaft and rotor cushioning effect.
Utility model content
The technical problems to be solved in the utility model overcomes existing defect, provides a kind of damping rotor or anti-electric anti-corrosion structure, adds one deck non-conductive and have the separator of cushioning effect, effectively can solve the problem in background technology between rotating shaft and rotor core.
In order to solve the problems of the technologies described above, the utility model provides following technical scheme:
A kind of damping rotor of the utility model or anti-electric anti-corrosion structure, comprise rotor core, described rotor core be bonded with some magnetic shoes, and press-in rotating shaft in described rotor core, described rotating shaft is provided with one deck separator.
As a kind of optimal technical scheme of the present utility model, described separator is non-conductive and has rubber or the plastics of cushioning effect.
The beneficial effect that the utility model reaches is:
Between rotating shaft and rotor core, add one deck non-conductive and have the separator of cushioning effect, reduce the induced voltage between rotor and cushioning effect, can effectively prevent bearing electrostatic from corroding, improve the useful life of motor bearings and improve motor noise.
Accompanying drawing explanation
Accompanying drawing is used to provide further understanding of the present utility model, and forms a part for specification, is used from explanation the utility model, does not form restriction of the present utility model with embodiment one of the present utility model.
In the accompanying drawings:
Fig. 1 is the structural representation of a kind of damping rotor described in the utility model embodiment or anti-electric anti-corrosion structure;
Number in the figure: 1, rotating shaft; 2, rotor core; 3, magnetic shoe; 4, separator.
Embodiment
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described, should be appreciated that preferred embodiment described herein is only for instruction and explanation of the utility model, and be not used in restriction the utility model.
Embodiment: as shown in Figure 1, a kind of damping rotor of the utility model or anti-electric anti-corrosion structure, comprise rotor core 2, described rotor core 2 is bonded with some magnetic shoes 3, press-in rotating shaft 1 in described rotor core 2, it is characterized in that, described rotating shaft 1 is provided with one deck separator 4.Described separator 4 is non-conductive and has rubber or the plastics of cushioning effect.
The utility model add between rotating shaft 1 and rotor core 2 one deck non-conductive and have cushioning effect separator 4, reduce the induced voltage between rotor 1 and cushioning effect, effectively can prevent bearing electrostatic from corroding, improve the useful life of motor bearings and improve motor noise.
Last it is noted that the foregoing is only preferred embodiment of the present utility model, be not limited to the utility model, although be described in detail the utility model with reference to previous embodiment, for a person skilled in the art, it still can be modified to the technical scheme described in foregoing embodiments, or carries out equivalent replacement to wherein portion of techniques feature.All within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection range of the present utility model.
