Description
Technical field
The utility model relates to motor manufacturing technology field, relates in particular to a kind of micro-machine insulated end cover.
Background technology
Due to stator and rotor the air gap inhomogeneous, the reason such as stator silicon steel sheet seam, axle center and magnetic field center are inconsistent,Rotor is inevitably rotated in not exclusively symmetrical magnetic field, cause producing shaft voltage in rotating shaft, when it runs up to certain journeyDegree, can puncture bearing film and form shaft current.
In order effectively to reduce the galvanic corrosion of shaft current to motor bearings, improve bearing service life, conventionally adopt insulation bearing to blockThe approach that induced-current flows through from bearing, thus effectively play the effect of protecting bearing. But because insulation bearing is compared plain bearing2～3 times of price mean heights, use also uneconomical. So most producers adopt insulated end cover or insulated bearing pedestal to replace insulation bearing,Play insulating effect, thereby reduce motor cost.
Be studied in the industry, for example Chinese patent discloses a kind of insulating end cover structure of wind-driven generator, application number:201520550715.4, the applying date: 2015-07-27, comprises insulating sleeve, insulation sleeve, securing member, insulation board and end cap;Securing member is fixed on end cap on insulating sleeve; Insulation sleeve is arranged between insulating sleeve and securing member; Insulation board is arranged on absolutelyBetween edge axle sleeve and end cap; Securing member connects insulating sleeve, insulation sleeve, insulation board and end cap; Insulating sleeve comprises axleCover and layer cover the insulating barrier on the contact-making surface between axle sleeve and end cap.
Technique scheme is for a kind of structure on wind-driven generator, has directive significance for other motor/generators, butShould be noted that: when this technology applies to micro-machine, especially when family expenses motor, because family does not generally possess installationThe condition of perfect damper mechanism, its insulating sleeve, insulation board be due to long-term irregular vibration, easily tracking.
Utility model content
For the deficiencies in the prior art, the utility model provides a kind of long-lived micro-machine special isolation end cap.
The technical solution of the utility model is:
A kind of micro-machine insulated end cover, comprises axle sleeve, insulation sleeve, fastening structure, insulation board and end cap, it is characterized in that:Described axle sleeve periphery coordinated insulation is arranged with groove, and described insulation sleeve is set in the groove of axle sleeve periphery, and described end cap is set inInsulation sleeve periphery and being connected with axle sleeve by fastening structure, is also provided with insulation board between described axle sleeve and end cap;
Described fastening structure comprises screw, nut, buffer insulation pad, the buffer insulation collar and is arranged on the thread groove in end cap,Described screw periphery matching thread groove is provided with screw thread, and described screw coordinates peace through bossing and the insulation board of axle sleeve with thread grooveDress, the bossing of described screw periphery coordinated insulation plate and axle sleeve is provided with the buffer insulation collar, and described screw is positioned at outside axle sleevePart is provided with buffer insulation pad and nut; The benefit of this structure is: 1) fastening by screw, nut, thread groove threeRelation, locking axle sleeve and end cap to greatest extent, reduces oscillation space; 2) keep away by buffer insulation pad and the buffer insulation collarExempt from screw conduction vibration, further reduce axle sleeve and end cap generation Relative Vibration, thereby reduce the wearing and tearing of insulation board, insulation sleeve.
Further, the cross section structure of described insulation sleeve, insulation board is identical, includes tenacity-increased profax shock-resistant layer and epoxy treeFat insulation material layer, its effect is to possess very high impact resistance in effectively insulating.
Further, described buffer insulation pad is identical with the cross section structure of the buffer insulation collar, includes epoxy resins insulation materialThe bed of material and cushion rubber layer, its effect is the ability that further reduces screw conduction vibration.
Further, described end cap is connected with motor ground structure by electric wire, and its effect is to make end cap can not accumulate static.
Further, the casing of described end cap and motor is fixedly linked, and bearing is arranged in axle sleeve.
The beneficial effects of the utility model are: the utility model has designed the spiral shell that coordinates screw with the feature that is connected of end cap for axle sleeveGroove, by the strong fastening ability of screw, thread groove and nut, has effectively reduced the Relative Vibration of axle sleeve and end cap, therebyImprove the service life of insulating materials, in addition by the use of buffer insulation pad and the buffer insulation collar, reduced furtherThe vibration of screw, also further reduced the wearing and tearing of insulating materials.
