Description
Technical field
A kind of pedestal structure of fan is especially relevant for the pedestal structure of bearing and central siphon shape all-in-one-piece fan.
Background technique
Fan housing and pedestal are made of plastic cement material mostly at present, due to the choice for use plastic cement material, how can utilize the processing procedure of plastic rubber ejaculate molding to complete, because utilize the most effective and suitable diverse design of plastic rubber ejaculate molding.
But the product of completing that utilize plastic rubber ejaculate molding can produce the phenomenon that plastic cement shrinks or is out of shape, and plastic cement shrinks or the generation reason of distortion much hereby is listed below:
1. because moulding meat thickness ununiformity, otherness is excessive, and due to the easier cooling curing in the thin place of meat, meat thick place is stretched than the raw material of slow cool down, produces to shrink and sink.
2. more easily shrink PE, PP or PA type more obvious when the high temperature hot-die (but when arriving the Tm processing temperature because of crystalline material, crystallization is disintegrated, cooling rear density reduction, easily contraction, and formation shrink phenomenon) because of the crystallinity plastic cement.
3. because the finished product inhomogeneous cooling, cooling slow contraction is large, when crystallization is inhomogeneous, will causes and shrink uneven and be out of shape.
4. because the thick gap of meat of finished product is excessive, shrinkage varies in size and produces distortion.
Be depicted as known fan base structure as Figure 1A and Figure 1B, comprise that a pedestal 10 has a hollow axle tube that protrudes out 11 on it, and two bearings 12,13 are placed in this hollow axle tube 11.
This known fan base structure, be that after utilizing aforesaid plastic rubber ejaculate molding to complete this pedestal 10 and this hollow axle tube 11, (after namely being fabricated to the product of completing) utilizes external force sequentially to be forced in hollow axle tube 11 on two bearings 12,13 more at present.
Wherein be formed with one first accommodating chamber 111 and one second accommodating chamber 112 in this hollow axle tube 11, the vertical adjacent and setting that is communicated with of this first accommodating chamber 111 and the second accommodating chamber 112, these two bearings 12, one of them bearing 13 of 13 are forced into this second accommodating chamber 112 for oil-impregnated bearing via external force, and another bearing 12 is forced into this first accommodating chamber 111 for ball bearing via external force.Between this oil-impregnated bearing 13 and this second accommodating chamber 112 with the drive fit setting, between this ball bearing 12 and this first accommodating chamber 111 with the loose fit setting.
Only known technology has its problem to exist, because utilize plastic rubber ejaculate molding can produce the phenomenon of plastic cement shrink as the aforementioned or distortion, causing this first accommodating chamber 111 and this second room 112 to produce shrinks or distortion slightly, moreover these two bearings 12,13 one of them be friction tight setting, another is for the setting of loose fit, therefore can two bearings 12 of generation after these two bearings 12,13 are placed into the first accommodating chamber 111 and the second accommodating chamber 112,13 different axle center (as shown in Fig. 1 C, there is a gap A in two bearings 12,13 axle center).To cause so stuck and different sound.In addition, also will cause two bearings 12,13 retain strength excessive or too small, in case the retain strength of bearing is excessive, bearing easily is out of shape; The bearing retain strength is too small, and bearing is easy loose or dislocation.The conformity of assembling also can variation simultaneously, reduces manufacturing efficiency.

Then in the lump with reference to figure 2 and shown in Figure 4, with one second bearing 28, open-work 221 is put into this first space 25 of this hollow axle tube 21 after plastic rubber ejaculate molding is then one-body molded on this.And then make this second bearing 28 be positioned at the top of this clutch shaft bearing 27, and pass through these the first convex body 23 perpendicular separation settings between this clutch shaft bearing 27 and this second bearing 28.
Subsidiary one carry be, have a gap 29 between this clutch shaft bearing 27 and this second bearing 28, this gap 29 is defined by a thickness of this first convex body 23.More specifically, be exactly that this clutch shaft bearing 27 does not have this second bearing 28 of actual contact.Clutch shaft bearing 27 alleged in the utility model is preferably oil-impregnated bearing, and the second bearing 28 is preferably ball bearing, but also can be opposite setting or other bearings that is equal in other enforcements.
Then please refer to shown in Fig. 5 A, Fig. 5 B, Fig. 6 A and Fig. 6 B, mean the schematic top plan view of X-X ' and Y-Y ' hatching line in the 4th figure, aforesaid the first convex body 23 and this second convex body 24 are along the inner surface 211 continued circling settings (Fig. 5 A and Fig. 5 B) of this hollow axle tube 21.Or another implement aforesaid the first convex body 23 and this second convex body 24 along inner surface 211 intervals of this hollow axle tube 21 around setting, and have respectively a plurality of cracks 231,241 one-tenth radial settings.
Subsidiary one carry be, as shown in Figure 7, the utility model also comprises a fan frame 40, this pedestal 20 is positioned at the center of this fan frame 40, and is connected with this fan frame 40 via a plurality of connecting element 41 that are arranged on this pedestal 20 outsides.
The utlity model has at last following advantage:
1. clutch shaft bearing is coated in the second containing space by hollow axle tube via plastic rubber ejaculate molding, therefore can not make the hollow axle tube distortion because of extruding, the generation concentricity departs from, and is fixed by the first protuberance and the second protuberance, can not change with temperature and time that this clutch shaft bearing is got loose.
2. even form one because of this clutch shaft bearing in the step of ejection formation and this hollow axle tube, so can save the time of assembling clutch shaft bearing, improving production efficiency in whole fan installation step.
3. the second bearing can this clutch shaft bearing be the assembling of benchmark, makes the concentricity of two bearings easily control.
Although the utility model discloses as above with mode of execution; so it is not to limit the utility model; anyly be familiar with this skill person; within not breaking away from spirit and scope of the present utility model; when can be used for a variety of modifications and variations, therefore protection domain of the present utility model when look accompanying claim the person of deciding be as the criterion.
