Abstract
The utility model discloses a fan and structure of its axial center. Primarily, the axial center of the fan is made of metallic material, and a coating formed from ceramic material is coated outside the axial center. The axial center is introduced into and penetrated through a bearing of the fan, and the bearing is a pipe body made of ceramic material. Tee axial center is mutually sheathed into the bearing, and the coating is corresponding to the inner wall face of the bearing. Thereby, the interior of the axial center is provided with perfect hardness, and the exterior is provided with perfect degree of lubrication. The coefficient of friction between the axial center and the bearing is reduced when the fan rotates in high speed, and the effect of reducing noise and extending service life is thus realized.

Background technique
Fig. 6 is the perspective exploded view of known fan.As shown in Figure 6, flabellum 51 centers at fan 5 are provided with an axle center 52, and the centre in the framework 53 of fan 5 is provided with a bearing 54, the bearing 54 of fan is inserted and passes in axle center 52, make with bearing 54 usefulness metallic material in axle center 52, and bearing 54 is an oil-impregnated bearing, can make the axle center 52 of fan 5 have preferable hardness with bearing 54, and can cooperatively interact when fan 5 high speed rotating produces stronger toughness.
Though the axle center 52 and the bearing 54 of fan 5 have preferable hardness, but because it is metallic material and makes, therefore, (when the oil content in the bearing 54 reduces) very easily causes the lubricity deficiency of 54 on axle center 52 and bearing because of the two rigidity under long-term the use, and easily cause the generation of static and because the mutual wearing and tearing of 54 on axle center 52 and bearing, thereby make fan 5 when high speed rotating, have noise to produce, shortened the working life of fan 5.
Content of the present utility model
Main purpose of the present utility model is to solve the defective that exists in the prior art.The utility model redesigns the axle center that fan used, make the axle center have preferable hardness, and and bearing between have more lubricity, thereby reduced fan friction factor between described axle center and bearing when running up, reach the effect that reduces noise and increase the service life.
In order to realize described purpose, a kind of fan of the present utility model, the axle center that fan used is made with metallic material, be coated with one by the formed coating of stupalith in the outside, axle center, and the bearing of described fan is made back and mutual sheathed connection of described axle center with stupalith, makes the coating in described axle center corresponding with the internal face of bearing.
Fan of the present utility model can reach reduce fan in the running noise and prolong working life of fan.

Embodiment
Fig. 1, Fig. 2, Fig. 3 are respectively three-dimensional decomposition of the present utility model, the three-dimensional appearance schematic representation in axle center, the profile status schematic representation in axle center.As Fig. 1, Fig. 2, shown in Figure 3, a kind of fan of the present utility model comprises: a framework 1, a bearing 2, a flabellum 3 and stator group 4.The utility model can make the inside, axle center of flabellum 3 have preferable hardness, and the outside has preferable lubricity, and can reduce fan friction factor between axle center and bearing when running up, and reaches the effect that reduces noise and increase the service life.
Framework 1 is provided with a bearing part 11, and bearing part 11 extensions are provided with a sleeve 12.
Bearing 2 is a pipe structure, be arranged in the sleeve 12, and bearing 2 is made by stupalith.
Flabellum 3 comprises: a wheel hub 31; A plurality of blades 32 that are arranged on wheel hub 31 outer rims; One magnetic 33 and that is arranged on wheel hub 31 inner edges is arranged on the axle center 34 of wheel hub 31 centre.Axle center 34 is made by metallic material, and the appropriate location of 34 outsides is coated with one by the formed coating 35 of stupalith (as Fig. 2, shown in Figure 3) in the axle center, makes the inside in axle center 34 have preferable hardness, and the outside has preferable lubricity.The axle center 34 of flabellum 3 centre is inserted through bearing 2, and the coating 35 in axle center 34 is corresponding with the internal face of bearing 2.In addition, the appropriate location of an end of 34 and contiguous coating 35 is provided with a groove 341 of fixedlying connected with flabellum 3 centre in the axle center, and 34 the other end and the appropriate location that is close to coating 35 are provided with a snapping portion 342 in the axle center.Snapping portion 342 passes bearing 2 and is connected with a top supporting part 36.And top supporting part 36 comprises a fixing-assembly 361, and fixing-assembly 361 is fixedly installed in the snapping portion 342; One elastic component 362 is located on the axle center 34, and an end face of pulling at bearing 2 and fixing-assembly 361 is pushed up at its two ends respectively.As shown in Figure 5, the coating 35 in axle center 34 is arranged on the precalculated position in the bearing 2, and is corresponding with the internal face of bearing 2.
