Description

The fan spindle bearing fixed structure

Technical field

The utility model provides a kind of fan spindle bearing fixed structure, espespecially a kind ofly avoids bearing to rotate in bearing hole and slides and prevent the fan spindle bearing fixed structure of bearing wear or inefficacy.

Background technique

Because the progress of Technology Times, the operational effectiveness of electrical assembly is more and more higher, so that the requirement to the heat dissipation of electrical assembly also increases to heat-sink unit thereupon.

Take computer main as example, the heat that its center of inside processing unit (CPU) produces accounts for major part, in addition, central processing unit when heat gradually rising can cause and carry out usefulness and reduce, and when accumulation of heat is higher than its allowable limit, will force computer down, severe patient more may cause the damage phenomenon; And, for solving the problem of electromagenetic wave radiation, usually seal this computer main with the cabinet housing, so that how the heat energy of central processing unit and other heating spare part (or claiming assembly) is derived fast, become an important topic.

When operating, can produce high temperature again or such as large scale electronic equipments such as general work station or servers, when if its operational temperature surpasses certain operating temperature, its high temperature then can affect work station, the task performance of the main frames such as server, even affect work station, electrical assembly in the main frames such as server burns and then causes fault, especially stored database or archives are even more important in work station or the server, therefore it is of short duration when machine or damage and can cause equally follow-up larger loss, so, work station, server when setting up, this how heat dissipation problem temperature is maintained be considerable design link in the operating temperature range.

Therefore dynamical heat-sink unit has been one of most important Research Emphasis of industrial circle today, be provided with heat-sink unit and by this heat-sink unit described electrical assembly dispelled the heat with the electrical assembly to this generation high temperature, described heat-sink unit is generally radiator or radiating fin correspondence and mixes a radiation fan and carry out heat radiation work.

See also shown in Figure 1, three-dimensional assembled sectional view for the radiation fan of known technology, described radiation fan 1 has a base 11 and a rotor set 12 and stator group 13, this base 11 has a beam barrel 111, and in these beam barrel 111 inside two bearings 112 is set, this bearing 112 utilizes the tolerance fit with beam barrel 111 internal diameters, to make its bearing 112 can be arranged in the beam barrel 111 and can avoid beam barrel 111 to deviate from, and these beam barrel 111 outer cover are provided with described stator pack 13, and this rotor set 12 has a wheel hub 121, a plurality of flabellum bodies 122 and an axostylus axostyle 123, this axostylus axostyle 123 is inserted in aforementioned bearings 112, when described radiation fan 1 running, axostylus axostyle 123 relative these bearings 112 of this rotor set 12 rotate, but this bearing 112 does not have the setting of any location, so that described axostylus axostyle 123 relative these bearings 112 are done when rotating, this bearing 112 can be subjected to the impact of axostylus axostyle 123 and rotate or slide, and behind described radiation fan 1 long time running, the phenomenon generation that described bearing 112 has wearing and tearing and produces chip or powder with beam barrel 111, and then cause bearing 112 inefficacies and rotor set 12 runnings to have some setbacks.

So known technology has following shortcoming:

1. bearing can be subjected to the impact of axostylus axostyle and rotate or slide;

2. bearing and beam barrel have wearing and tearing and produce chip or powder;

3. the running of bearing failure and rotor set has some setbacks.
