Description

Bearing integrated structure

Technical field

The present invention relates to a kind of bearing integrated structure, espespecially a kind of bearing combination for improving bearing and beam barrel service life Structure.

Background technology

Due to the progress of Technology Times, the operational effectiveness of electronic component is higher and higher, so as to heat-sink unit to electronics The requirement of the heat dissipation of element is consequently increased.

By taking host computer as an example, heat caused by its internal central processing unit (CPU) accounts for major part, in addition, central Processing unit can cause to perform efficiency reduction when heat gradually rises, and when accumulation of heat is higher than its allowable limit, it will compel Computer is set to work as machine, severe patient is more likely to can Zao Cheng Ruined damage phenomenons；Also, to solve the problems, such as electromagenetic wave radiation, typically with machine Tank shell closes the host computer, so that how by central processing unit and the thermal energy of other fever spare parts (or element) Quick export, becomes an important topic.

Again or such as general work station or servomechanism large scale electronic equipment can produce high temperature in running, if its operational temperature During more than certain operating temperature, its high temperature can then influence the task performance of the hosts such as work station, servomechanism, or even can influence work Stand, the electronic component Shao Ruined in the host such as servomechanism in turn result in failure, stored data especially in work station or servomechanism Storehouse or archives are even more important, therefore its of short duration loss worked as Ji Huo Ruined damages and can equally cause follow-up bigger, therefore, work station, For servomechanism when setting up, how heat dissipation problem makes temperature maintain in operating temperature range is considerable design link for this.

Therefore dynamical heat-sink unit has been one of the most important Research Emphasis of industrial circle today, with high to the generation The electronic component of temperature is provided with heat-sink unit and is radiated by the heat-sink unit to the electronic component, the heat-sink unit Usually radiator or radiating fin correspondence mix a radiator fan and carry out heat dissipation work.

Refering to Figure 1, the stereogram of the bearing integrated structure for the prior art, the radiator fan 1 has a bottom 11 and one rotor set 12 of seat and stator group 13, which has a beam barrel 111, and sets an axis in the inside of beam barrel 111 Hold 112, which is the tolerance fit using with 111 internal diameter of beam barrel, to make its bearing 112 may be disposed in beam barrel 111 and Beam barrel 111 can be avoided to deviate from, and 111 outer cover of beam barrel is equipped with the stator pack 13, and the rotor set 12 has a wheel hub 121st, multiple 122 and one axle center 123 of flabellum body, the axle center 123 are inserted in aforementioned bearings 112, when the radiator fan 1 operates When, the axle center 123 of the rotor set 12 is rotated relative to the bearing 112, but the bearing 112 is any fixed in not having in beam barrel 111 The setting of position so that the axle center 123 is done relative to the bearing 112 when rotating, the bearing 112 understand be influenced by axle center 123 and Rotate or slide in being produced in beam barrel 111, and after 1 long time running of radiator fan, the bearing 112 and beam barrel 111 The phenomenon for having abrasion and producing chip or powder produces, and then causes the failure of bearing 112 to have some setbacks with the operating of rotor set 12.

The above, the prior art have the disadvantage that：

1. bearing can be influenced by axle center and rotate or slide；

2. reduce bearing and beam barrel service life.

Therefore, how to solve the above problems and deficiencies of the prior art, as inventor is with being engaged in the industry Relevant manufactures are suddenly where improved direction to be studied.

The content of the invention

Therefore, effectively to solve the above problems, it is a primary object of the present invention to provide one kind to increase bearing and beam barrel The bearing integrated structure of service life.

The secondary objective of the present invention, is to provide a kind of bearing for making bearing rotate or slide from the influence in axle center Integrated structure.

In order to achieve the above object, the present invention provides a kind of bearing integrated structure, including：One pedestal, has a beam barrel, the beam barrel Formed by being protruded out at the base central, and formed with an accommodating space in the beam barrel；One rotor, has a wheel hub and by the wheel hub Centre extends an axle center, and the side of the wheel hub is equipped with multiple blades, which is fixedly arranged on wheel hub centre；At least One bearing, is located in the accommodating space, which has an axis hole, and the axle center other end wears the bearing and accommodating sky Between；It is characterized in that：An at least groove, can be opened in the beam barrel inner wall and bearing outer wall or any of which, and the ditch at the same time Groove is connected with the accommodating space.

The beam barrel inner wall is more corresponded to and is located in the holding part formed with an at least holding part, the bearing.

One has more been installed with the groove and molten has filled out thing.

Filled out using laser welding manner in described melt on thing to make the bearing and beam barrel engage fixation.

With more a fan frame, the pedestal is arranged at the fan frame central position.

The fan frame accommodates a stator with more an accommodation space, which is made of multiple silicon steel sheets and is wound with multiple Coil.

The beam barrel inner wall longitudinally offers the groove, and the groove that the bearing outer wall system corresponds to the beam barrel is combined solid It is fixed.

The bearing outer wall longitudinally offers the groove, and the groove of the bearing corresponds to the beam barrel inner wall and is combined admittedly It is fixed.

By the design of this structure of the invention, it can be melted in foregoing groove content equipped with one and fill out thing, and welded using laser Mode be welded in it is described it is molten fill out to make the bearing and beam barrel be bonded with each other fixation on thing, and then prevent shadow of the bearing from axle center Ring and rotate or slide, reach the service life for improving bearing and beam barrel.
