Abstract
A fan spindle bearing fixing structure and a fan applying the fan spindle bearing fixing structure comprise a base seat and a ring body. One side of the base seat is convexly and extendedly provided with a shaft barrel. A shaft hole used for containing a spindle bearing is arranged inside the shaft barrel. The ring body is arranged on the outer side of the shaft barrel in a sleeved mode and is provided with an opening hole. The inner side of the opening hole is arranged on the outer side of the shaft barrel in an attached mode, and extrudes the outer side of the shaft barrel towards the inner of the shaft hole, wherein the inner of the opening hole is matched with the outer side of the shaft barrel. Due to the fact that the ring body is arranged in a sleeved mode and presses the outer side of the shaft barrel towards the inner of the shaft hole, the shaft hole is enabled to shrink cavity to fix the spindle bearing, and therefore effects of reducing cost are achieved.

Embodiment
Characteristic on above-mentioned purpose of the present utility model and structure thereof and the function will be explained according to appended graphic preferred embodiment.
The utility model is a kind of fan spindle bearing fixed structure and the fan of using it, sees also Fig. 1, Fig. 2 A, Fig. 2 B shows, is Decomposition and composition and the generalized section that shows the first preferred embodiment of the present utility model; This fan spindle bearing fixed structure and the fan of using it comprise a pedestal 10 and a ring body 14, this pedestal 10 has a beam barrel 101, this beam barrel 101 protrudes out formation from the side on this pedestal 10, and be provided with an axis hole 1014 and a platform 1016 in it, the central authorities of this platform 1016 from these beam barrel 101 inboards towards axis hole 1014 protrude out, in order to bearing one bearing 12, make this bearing 12 be installed with in this axis hole 1014.
The aforementioned beam barrel 101 of person is provided with a first end 1011 and one second end 1012 in addition, and this first end 1011 is installed in the centre of this pedestal 10, and this second end 1012 extends axially formation from this first end 1011.And the material of described ring body 14 is that metal material, plastic cement material and elasticity macromolecule material are wherein arbitrary; And this ring body 14 is set on these beam barrel 101 outsides, and it has a perforate 141, these perforate 141 inboards are sticked on this beam barrel 101 outsides, and must be to relative beam barrel 101 outsides towards axis hole 1014 interior extruding, that is be set on should the second end 1012 of beam barrel 101 by the perforate 141 of described ring body 14, make this second end 1012 be subject to these perforate 141 inboards and inwardly push (or pressing) and resiliently deformable towards axis hole 1014 centers, to dwindle the bore of these the second end 1012 interior axis holes 1014, use the effect that reaches rigid bearing 12.
In addition, when implementation, the user can be according to described bearing 12 is subjected to pressing tightness size requirement in beam barrel 101, this ring body 14 of design modifying is set in the degree of depth that is pressed on the second end 1012 of this beam barrel 101, that is as consult Fig. 3 A, Fig. 3 B and show that ring body 14 compression distance on the second end 1012 of beam barrel 101 is darker, the suffered pressing tightness of the relative bearing in this beam barrel 101 12 is larger.
Moreover on the second end 1012 of aforementioned beam barrel 101 during sheathed ring body 14, the diameter of this first end 1011 is greater than the diameter of this second end 1012, and beam barrel 101 global shapes of this moment roughly are taper; But when the actual enforcement of the utility model, the user can be in advance according to the demand to quality of fit and tolerance between bearing 12 and the beam barrel 101, design changes the shape of described beam barrel 101, that is consult Fig. 4 A, Fig. 4 B shows, integral body during the second end 1012 not sheathed ring body 14 of this beam barrel 101 roughly is taper, and first end 1011 diameters of this beam barrel 101 are less than the diameter of this second end 1012, so when on the second end 1012 of beam barrel 101 during sheathed ring body 14, perforate 141 inboards that are subject to this ring body 14 are towards axis hole 1014 interior extruding (or pressing) and resiliently deformable, to dwindle the bore of these the second end 1012 interior axis holes 1014, use the effect that reaches rigid bearing 12.
Therefore, be set in the design that integrally combines on beam barrel 101 outsides of pedestal 10 by ring body 14 of the present utility model, get the effect of effectively avoiding bearing 12 to get loose and reaching rigid bearing 12, and then more can promote the effect person of bearing 12 and beam barrel 101 quality of fits and tolerance.
In addition, owing to being set on beam barrel 101 outsides by this ring body 14 in the manufacture process, except the effect that can reach rigid bearing 12 and minimizing built-up time, and then more effectively promote beam barrel 101 and bearing 12 quality of fits and tolerance and the effect person who saves cost of production.
See also Fig. 5, Fig. 6 shows, show the second preferred embodiment of the present utility model decomposition and the combination schematic diagram; The structure of this preferred embodiment and connection relationship and effect thereof are roughly identical with aforementioned the first preferred embodiment, its both differences be in: be provided with a plurality of protuberances 142 in the perforate 141 of aforementioned ring body 14, described protuberance 142 extends formation along these perforate 141 inboards towards these perforate 141 centre, and be sticked on beam barrel 101 outsides of correspondence, and to relative beam barrel 101 outsides towards axis hole 1014 interior extruding, that is the second end 1012 of 142 pairs of relative beam barrels 101 of described protuberance is towards axis hole 1014 interior extruding (or pressing) and the elasticity sex change, reach rigid bearing 12 and promote bearing 12 and the effect of beam barrel 101 quality of fits and tolerance to dwindle the bore of these the second end 1012 interior axis holes 1014, to use.
In addition the person is formed in a plurality of protuberances 142 of this preferred embodiment and is the equi-spaced apart spread configuration on these perforate 141 inboards and explains, but is not limited to this, when implementation, also can be not equi-spaced apart spread configuration, closes first Chen Ming.
See also Fig. 7, Fig. 8 A, Fig. 8 B shows, shows Decomposition and composition and the generalized section of the 3rd preferred embodiment of the present utility model; This this preferred embodiment mainly is that fan spindle bearing fixed structure of the present utility model and the fan of using it are applied on the fan 1, aforementioned fan 1 comprises a framework 15, one rotor 16 and a stator 17, aforementioned pedestal 10 is arranged in the framework 15, and it is pivoted mutually with relative rotor 16, and this stator 17 is set on described beam barrel 101 outsides, and adjacent correspondence is sheathed on the ring body 14 on the second end 1012 of beam barrel 101, so when rotor 16 running, the second end 1012 by 14 pairs of these beam barrels 101 of ring body is towards axis hole 1014 interior extruding (or pressing) and resiliently deformable, to dwindle the bore of the second end 1012 interior axis holes 1014, so that described bearing can be stabilized in this beam barrel 101 and rotor 16 relative movement, use allowing fan 1 reach the stable effect of running.
In addition, the circumference side of beam barrel 101 second ends 1012 of the present utility model can be provided with at least one axial grooving (or becoming claw-like and the tool elastic stretch) (not shown), in order to the sheathed convenience person of this ring body 14 of arranging in pairs or groups.
The above, the utility model has advantages of following compared to known electric fan technology:
1. have the effect that reaches rigid bearing, and then effectively promote the effect of bearing and beam barrel quality of fit and tolerance;
2. saving cost;
3. save man-hour.
Only the above only is better feasible embodiment of the present utility model, and all variations that utilizes the above-mentioned method of the utility model, shape, structure, device to do all should be contained in the claim scope of this case.
