Abstract

The utility model discloses an improved balancing structure for an annular axial flow fan, which comprises a hub and an annulus. The annulus is arranged around the outer side of the hub, at least one balancing region is defined on the annulus and used for being removed when a counterweight is balanced so that the balancing region can balance the weight of fan blades when the fan rotates and the fan can balance and stabilize a rotator. Therefore, the problem that the shock is caused as the fan is not balanced is avoided, and the functions of saving material cost and construction cost are achieved.

Description

The improvement of annular axial flow fan balanced structure

Technical field

The utility model relates to a kind of balanced structure, but the degree of balance that refers to a kind of rapid adjustment annular axial flow fan especially keeping equilbrium running, and the annular axial flow fan balanced structure that can save material and construction cost simultaneously improves.

Background technology

The electronics information product (for example: popularize day by day and use more extensive by use computer etc.), because it is rapid that demand drives the technical development of electronics IT industry, impel the electronics information towards carrying out the trend development that arithmetic speed promotes, access capability increases, causing the spare part in the aforementioned electronic information product to have high temperature to supervene often at working at high speed, is to be provided with radiator and radiator fan in its position and the spare part in the general electronics information product is taked in order to the mode that solves heat radiation.

And general radiator fan roughly is divided into two kinds of axial flow fan and centrifugal fans, and we illustrate with ring-like axial flow fan at present, annular axial flow fan structure of the prior art is that the wheel hub at annular axial flow fan forms some flabellums outwardly, its flabellum outer end one individuality is extended with a ring body, and described annular axial flow fan is in penetrating molded manufacturing process, injected plastics material is easy inhomogeneous when penetrating often, cause whole wheel hub, the weight inequality of flabellum or ring body, and have influence on the balance that annular axial flow fan rotates, if its wheel hub, when the mutual weight of flabellum or ring body is unequal, situation that will run-off the straight when rotating, cause increasing the central shaft and the friction between the axle sleeve of annular axial flow fan and rocking, described friction and shaking phenomenon not only make annular axial flow fan produce noise, and the axle center that can cause annular axial flow fan accelerates fatigue and shortens useful life of annular axial flow fan, more will reduce the overall quality of the product mix of using described annular axial flow fan, and also can cause phenomenons such as heat dissipation is clear.

There is manufacturer to adjust the uneven situation of its annular axial flow fan weight now via the regional counterweight on its wheel hub, as shown in Figure 1, it is the stereogram of annular axial flow fan balanced structure of the prior art, its annular axial flow fan 10 mainly has a wheel hub 11 and a ring body 12,12 of described wheel hub 11 and described ring bodies have at least one flabellum 13, and wheel hub 11 has different wheelbases with ring body 12 respectively with respect to annular axial flow fan 10 centers, and has at least one groove 111 on the described wheel hub 11, and its annular axial flow fan 10 is when the unequal or situation that tilts of weight takes place in when running, its settling mode is to adjust uneven weight on wheel hub 11, via the formation of groove 111 to carry out counterweight, but because of its wheel hub 11 and ring body 12 with in have relative gap in the heart, therefore, in on its wheel hub 11, carrying out the several times that the required weight of counterweight need be higher than ring body 12, just can reach the purpose of balance, therefore it is high many with consume material to carry out the spent construction cost of counterweight on wheel hub 11, again after carrying out the counterweight of annular axial flow fan 10 via wheel hub 11, when its annular axial flow fan 10 turns round, it is easily same because the influence on the weight of ring body 12 inequality and the wheelbase causes annular axial flow fan 10 to rotate the situation of run-off the straight, cause increasing central shaft and the friction between the axle sleeve and the shaking phenomenon of annular axial flow fan 10, also therefore need expend the engineering time adjusts weight; So prior art has following shortcoming:

On wheel hub, carry out counterweight and need expend the purpose that more material just can reach balance.

When on wheel hub, carrying out equilbrium running that counterweight reached easily because of the wheelbase of ring body and weight is unequal influences.

Need consume material cost and construction cost.

Therefore, because every shortcoming of being derived in the above-mentioned prior art, creator of the present utility model exhausts its intelligence then, concentrates on studies and is innovated improvement, finally successfully the improvement of the utility model annular axial flow fan balanced structure is finished in research and development, is a creation of promoting effect in fact.

The utility model content

Therefore, in order effectively to solve the above problems, main purpose of the present utility model, but the degree of balance that provides a kind of rapid adjustment annular axial flow fan is to keep the annular axial flow fan balanced structure improvement of equilbrium running.

Another purpose of the present utility model provides a kind of annular axial flow fan balanced structure improvement of saving material and construction cost.

Another purpose of the present utility model provides and a kind ofly can be pasted with separator on equilibrium region, influences the annular axial flow fan balanced structure improvement of the aerodynamic characteristic of electric fan to avoid formed equilibrium region after the balanced operation.

For reaching above-mentioned purpose, the utility model provides a kind of annular axial flow fan balanced structure improvement, mainly comprise: a wheel hub and a ring body, described ring body is around being arranged at the wheel hub outside, and be formed with an annular channel between its wheel hub and ring body, be provided with plural flabellum in the described annular channel, the described flabellum two ends of waiting have a inner and an outer end respectively, described the inner is connected the outside of described wheel hub and the inboard that described outer end is connected described ring body, and the equilibrium region that defines at least one place on its ring body obtains balance for removing and forming described equilibrium region with the weight that makes described annular axial flow fan.
