Abstract
The heat dissipating fan has one bearing assembly in the center and including mainly one metal sleeve and two bearings installed indirectly inside the metal sleeve. During manufacture of the heat dissipating fan, the bearing assembly is first set inside one corresponding fan mold, molten plastic is then injected into the mold and fan frame with combined bearing assembly may be finally taken out.
Description
[technical field]
The invention relates to a kind of radiation fan manufacture method, particularly about a kind of radiation fan manufacture method of guaranteeing the two bearings concentricity.
[background technique]
Bearing is the significant components of radiation fan, and good bearing construction helps to prolong fan life, reduces the fan running noises.NANO Ceramic Bearing adopts nano zirconium oxide powder raw material sintering to form, it has long service life and anti abrasive characteristics, owing to do not need to carry out precise finish processing after the NANO Ceramic Bearing moulding, its cost is also low than the general ceramic bearing that needs to carry out precise finish processing after the moulding, so be widely used on the computer heat radiation fan recently.But the cost of material of NANO Ceramic Bearing is comparatively expensive, if make the NANO Ceramic Bearing of length, its cost is higher.When so if the giant brain cooling fan adopts NANO Ceramic Bearing, generally be adopt two NANO Ceramic Bearing at interval the suitable length cover be set to the fan shaft periphery in case the spline axle is shaken when pivoting.
Shown in Figure 3 is normally used fan mould partial sectional view, this fan mould 10 mainly comprises a patrix 12 and a counterdie 14, this patrix 12 all is equipped with a core rod 16 with these counterdie 14 central authorities, and this core rod 16 cooperates the gabarit of this fan mould 10 can form an injection molding space 18.18 inject the plastics of fusions toward this injection molding space, treat that plastic cool solidifies the fan housing 20 that the back demoulding gets final product as shown in Figure 4.But because micro-deformation can take place after solidifying in the plastic cool of fusion, so the axle sleeve 22 of this fan housing 20 its internal diameter on axial length can produce the deviation of different sizes.If when using in the axle sleeve 22 that just two NANO Ceramic Bearing 10 is assembled to this fan housing 20 behind fan housing 20 demoulding cooling shapings such as bearing assembly method commonly used, the problem that the central axis of two NANO Ceramic Bearing 10 is difficult to be consistent often appears.Because NANO Ceramic Bearing 10 extreme hardness and the center capacity of self-regulation of ball bearing of not having, if can not guarantee the central axis unanimity of two NANO Ceramic Bearing 10, difficulty will take place in fan shaft when turning round in NANO Ceramic Bearing 10, cause noise to increase and the lost of life.
[summary of the invention]
The object of the present invention is to provide a kind of radiation fan manufacture method of guaranteeing the two bearings concentricity.
For achieving the above object, the present invention has adopted following technological scheme: the radiation fan central authorities of radiation fan manufacture method of the present invention are provided with a bearing unit, and this bearing unit comprises that a sleeve pipe and two is attached to the bearing in this sleeve pipe at interval.When making this radiation fan, it mainly comprises the following steps: this bearing unit is attached in the fan mould, and this bearing unit cooperates this fan mould to form an injection molding space; The plastics of fusion are injected in the injection molding space of this fan mould; Be a fan housing behind the plastics coagulation forming of fusion, take out this bearing unit and this fan housing one this moment again from fan mould, can obtain a fan housing that has been combined as a whole with this bearing unit.
Compare with prior art, thereby the two bearings that radiation fan manufacture method of the present invention adopts is closely to be fixed to earlier to form a bearing unit in the metal sleeve, again this bearing unit is attached to fan mould, then with fan housing one injection molded, so this radiation fan manufacture method can guarantee effectively that the center line of two bearings is consistent, thereby the plastic cool distortion that solves fusion causes the fan sleeve diameter to produce deviation, and the two bearings that causes being assembled in the fan axle sleeve is difficult to guarantee the problem of concentricity, and simplifies the fan assembly program.
The invention will be further described in conjunction with the embodiments with reference to the accompanying drawings.

[embodiment]
See also Fig. 1 and Fig. 2, fan housing 30 central vertical of this radiation fan upwards are equipped with a hollow shaft housing 32, are equiped with a bearing unit 34 in this axle sleeve 32, and this bearing unit 34 comprises a metal sleeve 36 and two NANO Ceramic Bearing 38.A flange 40 inwardly is equipped with at these metal sleeve 36 middle parts, and wherein the internal diameter of this flange 40 is less than the external diameter of this NANO Ceramic Bearing 38.These two NANO Ceramic Bearing, 38 central authorities are provided with an axis hole 42 and pivot within it with a ccontaining fan shaft (figure is mark not).This two NANO Ceramic Bearing 38 closely is attached to the both sides of these metal sleeve 36 flanges 40, thereby constitutes a combination of assembling at interval.Wherein this metal sleeve 36 is to be processed through precision lathe boring by metalliferous material (as copper rod), guarantees that two NANO Ceramic Bearing 38 that are attached in this metal sleeve 36 have concentricity preferably thereby its endoporus has higher processing precision.
The fan mould 50 of these fan housing 30 correspondences comprises a patrix 52 and a counterdie 54, these counterdie 54 central vertical upwards are equipped with a protruded stigma 56, be equipped with a core rod 58 under these patrix 52 mediads, earlier these bearing unit 34 covers are set to the protruded stigma 56 of this counterdie 54 when making this fan housing 30, again with patrix 52 and counterdie 54 corresponding combining, thereby form an injection molding space 60.The external diameter of this protruded stigma 56 approximates the internal diameter of NANO Ceramic Bearing 38 axis holes 42, and the external diameter of this core rod 58 then is slightly less than the external diameter of this metal sleeve 36.After patrix 52 and counterdie 54 were integrated, the top of this protruded stigma 56 was that the top with this core rod 58 connects.Toward the injection molding space 60 interior plastics that inject fusion of fan mould 50, be a radiation fan housing 30 behind the plastics solidification forming of fusion then.Separate patrix 52 and counterdie 54 this moment again, gets final product the fan housing 30 that the one taking-up has been combined as a whole with this bearing unit 34.
This radiation fan manufacture method is compared with common radiation fan manufacture method, thereby its two NANO Ceramic Bearing 38 that adopt are closely to be fixed to earlier in the metal sleeve 36 to form a bearing unit 34, again this bearing unit 34 is attached to fan mould 50, then with fan housing 30 one injection moldeds, so this radiation fan manufacture method can guarantee effectively that the center line of two NANO Ceramic Bearing 38 is consistent, the problem of the maintenance two NANO Ceramic Bearing concentricitys of required solution when solution is used two NANO Ceramic Bearing in radiation fan, the bearing assembly process that will carry out in the time of also can simplifying the radiation fan assembling.
This radiation fan manufacture method also can similar application in one or more various types of bearings are assembled to radiation fan, its bearing fixing is effective, comparatively easy to heart degree height, linkage editor.
