Abstract
Brushless fan of leak protection oil direct current especially indicates the oily brushless fan of direct current of a leak protection. Realize through following technical scheme: the utility model discloses constitute by stator device, rotor equipment, fixed bolster, bearing, flabellum, pivot and sealed lid, stator device by last insulating frame, down insulating frame and the blade of silicon steel constitute, stator device is fixed in on the excircle of the cylinder on the fixed bolster, in rotor equipment that motor shell and magnetic ring constitute was fixed in the ring groove of flabellum axle center position, pivot one end was fixed in flabellum axle center position, and the other end of pivot passes stator device's center to with the bearing bore in close contact with in the cylinder on the fixed bolster, cylinder top on the fixed bolster, the closing cap has the centre bore to be greater than the sealed lid of pivot diameter approximately, the bearing outer wall be equipped with longitudinal Groove, be equipped with the shaft shoulder in the pivot of being close to sealed lid department. The utility model discloses owing to do not carry out any change to original fan structure, only increase by a sealed lid on the hole of cylinder on the fixed bolster, leak protection oil effect is obvious.
Description
Technical field
The utility model relates to electric fan technical field, refers in particular to a kind of fan of oil-leakage-prevention.
Background technique
In use, owing to carrying out oily to running element, therefore the general oil-impregnated bearing that all adopts carries out selflubricating for electric fan, especially fan.But oil-impregnated bearing is in operation process, because the effect of temperature rise and centrifugal force, the grease in oil-impregnated bearing can overflow along rotating shaft, and then splashes to flabellum or periphery, causes fan normally to lubricate first, and working life reduces; Moreover adverse effect is caused to fan overall appearance.For this reason, the many research staff of industry hope and find out one and can protect oil, make again fan be unlikely and significantly change structure and cause processing difficulties, assembling difficult situation not easily.
The structure-improved that one " prevents the fan of leakage of oil " is proposed in the Chinese utility model patent of 200620057997.5, its design philosophy is designed to the upper insulating part in original stator apparatus with anti-oil cap and can matches each other with lower insulating part, and the combined type that the annular be aided with on elasticity oil deflector and wheel hub keeps off oily wall prevents oil leaking device.Although it is better that this structure keeps off oily effect, but need the mould of the upper insulating part in original stator apparatus, the mould of wheel hub all to need to redesign, process, rotating shaft need be processed, these, add the cost of production of fan virtually, be unfavorable for the popularization in market.How designing structure and simply, do not affect original structure design, is the important business that current industry is badly in need of solution.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency of the prior art, and provides a kind of oil-leakage-prevention fan.
The utility model is achieved by the following technical solution: the utility model is made up of stator apparatus, rotor arrangement, fixed support, bearing, flabellum, rotating shaft and sealing cover, described stator apparatus is made up of upper insulating frame, lower insulating frame and silicon steel sheet, the assemblying body of three is wound with coil, and stator apparatus is fixed on the cylindrical of the cylindrical body on fixed support; The rotor arrangement that motor shell and magnet ring are formed is fixed in the annular recess of flabellum shaft core position, flabellum shaft core position is fixed in rotating shaft one end, the other end of rotating shaft passes the center of stator apparatus, and with the brearing bore close contact in cylindrical body on fixed support, cylindrical body top on fixed support, capping has center hole to be about greater than the sealing cover of rotating shaft diameter, and described bearing outer wall is provided with longitudinal fluting, is provided with the shaft shoulder in the rotating shaft near sealing cover place.
On described sealing cover and fixed support, the endoporus of cylindrical body is interference fit.
Owing to not carrying out Wang to original fan structure, what changes the utility model, only on fixed support cylindrical body endoporus on increase by a sealing cover, prevent the successful of leakage of oil, and production and assembly operation is simple, produce tool and equipment interoperability higher, serve the effect of getting twice the result with half the effort.
Accompanying drawing illustrates:
Accompanying drawing 1 is one of the utility model exploded perspective view;
Accompanying drawing 2 is the utility model exploded perspective view two;
Accompanying drawing 3 is the utility model sectional view;
Accompanying drawing 4 is utility model works schematic diagram.
Embodiment:
As shown in accompanying drawing 1 ~ 4, the utility model is made up of stator apparatus 1, rotor arrangement 2, fixed support 3, bearing 4, flabellum 5, rotating shaft 6 and sealing cover 7, described stator apparatus 1 is made up of upper insulating frame 11, lower insulating frame 12 and silicon steel sheet 13, the assemblying body of three is wound with coil, and stator apparatus 1 is fixed on the cylindrical of the cylindrical body 31 on fixed support 3; The rotor arrangement 2 that motor shell 21 and magnet ring 22 are formed is fixed in the annular recess of flabellum 5 shaft core position, flabellum 5 shaft core position is fixed in rotating shaft 6 one end, the other end of rotating shaft 6 passes the center of stator apparatus 1, and with the bearing 4 endoporus close contact in cylindrical body 31 on fixed support 3, cylindrical body 31 top on fixed support 3, capping has center hole to be about greater than the sealing cover 7 of rotating shaft 6 diameter, and described bearing 4 outer wall is provided with longitudinal fluting, is provided with the shaft shoulder 61 in the rotating shaft 6 near sealing cover 7 place.
Described sealing cover 7 is interference fit with the endoporus of cylindrical body 31 on fixed support 3.
When fan turns, because the effect of temperature rise and centrifugal force, grease in oil-impregnated bearing 4 can overflow along rotating shaft 6, when closing on the shaft shoulder 61 place of sealing cover 7 and rotating shaft 6, due to the reason of wind speed, air pressure reduces, the grease overflowed throws away by the effect of centrifugal force, owing to being subject to the stop of sealing cover 7 and the shaft shoulder 61, the grease overflowed along the wraparound of sealing cover 7 internal layer to the outer wall of bearing 4, and along bearing 4 outer wall longitudinal fluting and be back to the bottom of oil-impregnated bearing 4, make bearing 4 lubricant grease obtain good maintenance, substantially increase the working life of fan.
