Description
Technical field
The utility model relates to heat sink technology field, relates in particular to a kind of guarantor's oil dustproof construction of DC fan.
Background technique
DC fan is widely used in all kinds of computers, electronics, and electrical equipment, communication, in office appliance, along with the expansion of purposes and the increase of competition, Consumer more and more requires its life-span long, and noise is low, and unit price is low.
The basic structure of DC fan is by fan housing or support, stator, rotor (flabellum) three part compositions.Bearing (citation form of bearing is mainly oil-impregnated bearing and ball bearing) is wherein housed, with the rotation in its support flabellum and axle center in the middle pipe of fan frame or support.The life-span of fan depends primarily on the working life of bearing arrangement.During due to conventional fan bearing operation, lubricant oil can throw away along rotor shaft two ends under centrifugal action, bearing is directly exposed to and in air, does not do any protective measures in addition, the fan in the running inner high temperature producing makes the oil in bearing be easy to volatilize lost, reduce its working life and increase noise, dust also easily enters in bearing arrangement, its oil is polluted, thereby increase surface friction drag, oil cap face is sealing state simultaneously, when running, oil is same out permeable from the gap of oil cap when high-temperature internal pressure, thereby level degree of variation reduces working life and increases noise.
Summary of the invention
The purpose of this utility model is to provide for the deficiencies in the prior art a kind of guarantor's oil dustproof construction of DC fan, can effectively protect oily oil-leakage-prevention, and dust protection enters, and reduces noise, increases working life.
For achieving the above object, the utility model adopts following technological scheme: a kind of guarantor's oil dustproof construction of DC fan, and it comprises rotor, stator assembly, fan frame and bearing; The root of described rotor is provided with flabellum axle center, and the root of rotor offers the circular groove for protecting oily dust control and noise absorption around flabellum shaft core position; Described bearing embeds the middle pipe inside of fan frame, and described stator assembly is set in middle pipe outside; Described rotor is passed bearing and is fanned frame to inserting by flabellum axle center, and the top of bearing is provided with oil-leakage-prevention sheet; Middle pipe bottom band oil storage tank and the snap ring of described fan frame, leave gap between bearing and snap ring, and the head in described flabellum axle center is block hook structure, this block hook structure and snap ring clamping.
Described snap ring surface trough of belt and oil circuit.
The bottom of the middle pipe of described fan frame is provided with wear-resistant gasket.
The utility model beneficial effect is: kind described in the utility model is protected the dustproof mutual-inserting type DC fan of oil, can effectively protect oily oil-leakage-prevention, and dust protection enters, and reduces noise, increases working life.
Brief description of the drawings
Accompanying drawing 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further described: as shown in Figure 1, guarantor's oil dustproof construction of a kind of DC fan described in the utility model, it comprises rotor 6, stator assembly 4, fan frame 1 and bearing 5; The root of described rotor 6 is provided with flabellum axle center 8, and the root of rotor 6 offers the circular groove 60 for protecting oily dust control and noise absorption around 8 positions, flabellum axle center; Described bearing 5 embeds middle pipe 10 inside of fan frame 1, and described stator assembly 4 is set in middle pipe 10 outsides; Described rotor 6 is passed bearing 5 and is fanned frame 1 to inserting by flabellum axle center 8, and the top of bearing 5 is provided with oil-leakage-prevention sheet 7; Middle pipe 10 bottom band oil storage tank 11 and the snap rings 2 of described fan frame 1, leave gap between bearing 5 and snap ring 2, and the head in described flabellum axle center 8 is block hook structure, this block hook structure and snap ring 2 clampings.Preferably, the surperficial trough of belt of described snap ring 2 and oil circuit, can save oil sealing cap.Preferably, the bottom of the middle pipe 10 of described fan frame 1 is provided with wear-resistant gasket 3, can effectively avoid damaging flabellum axle center 8.
Guarantor's oil dustproof construction of above-mentioned a kind of DC fan, is applicable to the fan kinds such as oil-impregnated bearing.Its principle is: one, reduce dust as far as possible and enter area and the probability of bearing 5 systems; Two, reduce the probability that the interior oil of bearing 5 outwards volatilizees and throws away, and the oil as far as possible bearing 5 being evaporated cohesion is back in former bearing 5 systems and uses as far as possible; Three, isolation and absorption that the noise of bearing 5 and the 8 operation friction generations of flabellum axle center is tried one's best.The basic shape bottom of fan frame 1, with oil storage tank 11 and the snap ring 2 that is connected as a single entity, is saved oil seal cover, and is had following characteristics: one, and global shape can be that circle can be also polygonal, the head in flabellum axle center 8 is that snap fit directly can be stuck in Zhi Kahuan 2; Three, bearing 5 leaves gap with snap ring 2 surfaces, and snap ring 2 surfaces are with groove and oil circuit.This new structure has overcome the shortcoming of conventional construction, can protect oil, dustproof, and the life-span can reach 38000H, also has the feature that noise is little simultaneously, and cost is lower with the fan of two roll structures than single ball bearing.
The above is only preferred embodiments of the present utility model, and the equivalence of doing according to structure, feature and principle described in the utility model patent claim therefore all changes or modifies, and is included in the utility model patent claim.
