Description

The fan assembly of oiliness bearing

Technical field

The present invention relates to a kind of fan assemblies of oiliness bearing more particularly to a kind of oiliness bearing effectively to fix and can keep away Exempt from the fan assembly because interfering the oiliness bearing for influencing operating due to close-fitting and dispensing are not easy to control.

Background technique

Press, electronics and IT products (such as: computer etc.) it is more extensive using increasingly widespread and application, due to demand band Dynamic electronics and information industry technology is quickly grown, and promotes electronic information to be promoted towards execution arithmetic speed, the increased trend of access capability Development, causes the spare part in aforementioned electronic information products to have high temperature to supervene often in working at high speed.

By taking main frame as an example, heat caused by internal central processing unit (CPU) accounts for major part, in addition, in Central Processing Unit will cause execution efficiency reduction when heat gradually rises, and when accumulation of heat is higher than its allowable limit, it will Computer down is forced, serious person is more likely to will cause damage phenomenon；Also, to solve the problems, such as electromagenetic wave radiation, usually The main frame is closed with chassis shell body, so that how by central processing unit and other fever spare parts (or element) Thermal energy quickly export, become an important topic.

And what the mode that general central processing unit is used to solve heat dissipation was taken is that radiator is arranged above it and dissipates Several fins have been set up in Hot-air fan, the side of radiator, direct with the surface of the other side (not with fin) of the radiator Premise central processing unit is contacted to enable thermal energy that can conduct to above-mentioned fin end, and forces to drive by heat loss through radiation and cooperation fan Stream take offence dissipate thermal energy rapidly.

It is the three-dimensional assembled sectional view one, two of the oil-containing bearing heat radiation fan of the prior art as shown in Figure 1A, 1B, this is dissipated Hot-air fan 1 mainly has a fan base 11, has a beam barrel 111 on the fan base 11, is provided with one in the beam barrel 111 and contains Oil bearing 12, but group is equipped with an impeller 13 on the fan base 11, is equipped with multiple blades 131 on the outside of the impeller 13, and in interior Side is extended with an axle center 132, which is arranged in the axis hole 121 of the oiliness bearing 12 and is buckled positioning, and it is dissipated In on oiliness bearing 12, which is fixedly installed in beam barrel 111 132 stable rotation of axle center when Hot-air fan 1 operates, And its oiliness bearing 12 and 111 fixed form of beam barrel have two, please refer to Figure 1A, one fixed form be in the oiliness bearing 12 with Dispensing processing procedure is carried out between beam barrel 111, and its glue material 14 is possible to flow via between the oiliness bearing 12 and the beam barrel 111 when dispensing To 121 position of axis hole, in turn resulting in when its axle center 132 rotates in oiliness bearing 12 has abnormal sound and the stuck situation in axle center 132 It generates, then please refers to 1B figure, another fixed form is to interfere its 12 outer diameter of oiliness bearing and 111 internal diameter of beam barrel tightly Match, but will lead to its axis hole 121 simultaneously when path interferometer close-fitting in its 12 outer diameter of oiliness bearing and beam barrel 111 and inside contract the extruding axis The heart 132, and then the situation for even causing axle center 132 stuck with operating that normally assembles for influencing its axle center 132 and axis hole 121 produces It is raw.

Therefore the prior art has the disadvantage that

1. dispensing processing procedure is not easy to control have been will form abnormal sound and has caused axle center stuck；

2. interference close-fitting, which can squeeze axle center, to be influenced normally to assemble and cause axle center stuck.

Therefore, above-mentioned existing and missing, the as inventor of this case and phase engaged in this industry how to be solved the problems, such as Shutout quotient is suddenly where the direction of improvement to be studied.

Summary of the invention

Therefore, effectively to solve the above problems, the main object of the present invention can be fixed effectively providing a kind of oiliness bearing And it can avoid the fan assembly for influencing the oiliness bearing operated due to close-fitting and dispensing are not easy to control because interfering.

Another object of the present invention is providing a kind of fan assembly of oiliness bearing that can effectively improve service life.

Another object of the present invention is providing a kind of fan assembly of oiliness bearing that can effectively reduce assembling cost.

For up to above-mentioned purpose, the present invention provides a kind of fan assembly of oiliness bearing, comprising: a pedestal has in one Pipe and the beam barrel extended by middle pipe, the beam barrel have a bearing hole, and are managed at opposite bearing hole position in this at least a pair of Socket part；One oiliness bearing is set in the bearing hole, and there is the oiliness bearing at least one set of socket part to butt up against the docking Portion；Stator group is sheathed at the beam barrel outer fix.

The oiliness bearing has an axle center hole.

An impeller has been further included, there is multiple blades and an axle center.

The docking section is that groove is depressed in pipe surface in this.

The group connecting part is that convex body protrudes from the oiliness bearing surface.

The docking section is that convex body protrudes from pipe surface in this.

The group connecting part is that groove is depressed in the oiliness bearing surface.

Whereby, being set by the group connecting part and docking section mutually group is fixedly installed on the oiliness bearing in bearing hole, and It can avoid because interfering the effect of influencing operating due to close-fitting and dispensing are not easy to control；Therefore the present invention has the advantage that

Oiliness bearing can be fixed effectively；

Can avoid interference close-fitting influences operating；

Solve the problems, such as that dispensing is not easy to control.
