Description
Technical field
The utility model provides a kind of fan assembly of tool oil-impregnated bearing, refers to especially a kind ofly reduce wear and reduce running noise and vibration, and improves the fan assembly of the tool oil-impregnated bearing in working life.
Background technique
Press; The electronics information product (for example: popularize day by day and use more extensive by use computer etc.); Because it is rapid that demand drives the technical development of electronics IT industry; Impel the electronics information towards carrying out the trend development that arithmetic speed promotes, access capability increases, cause the spare part in the aforementioned electronic information product to have high temperature to supervene often in working at high speed.
With the host computer is example; The heat that its central interior processing unit (CPU) is produced 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 to work as machine, severe patient more may cause the damage phenomenon; And, for solving the problem of electromagenetic wave radiation, seal this host computer with the cabinet housing usually, so that how the heat energy of central processing unit and other heating spare part (or claiming element) is derived fast, become an important topic.
And general central processing unit is taked in order to the mode that solves heat radiation is that radiator and radiation fan are set above it; One side of radiator has been set up some fins; With the surface of the opposite side (not having fin) of said radiator directly the aforementioned central processing unit of contact can conduct to above-mentioned fin end to make heat energy, and make the rapid dissipation of heat energy with cooperating fan pressure driving air-flow by heat loss through radiation.
As shown in Figure 1, for the oil-impregnated bearing radiation fan of known technology analyse and observe the combination schematic representation, this radiation fan 1 mainly has a fan base 11; Has a beam barrel 111 on this fan base 11; Be provided with a bearing 12 in this beam barrel 111, group is provided with an impeller 13 on this fan base 11 again, and these impeller 13 outer rings are provided with a plurality of blades 131; And be extended with an axle center 132 in the inboard; This axle center 132 is arranged in said bearing 12 and detains the knot location, and 132 in this bearing 12 and axle center are perfused with oil film 121 again, and its fan base 11 and bearing 12 and impeller 13 mutual position measurements are adjusted to the optimum operation position; Can be on bearing 12 with its axle center 132 when its radiation fan 1 operates by oil film 121 stable rotation; Therefore, its axle center 132 is only supported through the support force of oil film 121 with respect to the running position of bearing 12, but the support force that its radiation fan 1 its oil film 121 produces is still the eccentric force that is produced when turning round less than it; So its axle center 132 and 12 on bearing still have the phenomenon of frictional impact and produce; Again or after its radiation fan 1 receives external force collision; The striking force of external force also can make the skew of its shaft core position, even its axle center 132 is collided to bearing 12 produce vibration, causes this radiation fan 1 just to produce the noise of running and the facts such as noise of vibration because of its position deflection or collision; And also can increase simultaneously the abrasion condition of its axle center 132 and bearing 12, influence the working life of this radiation fan 1; Though again or the support force of its oil film 121 can make its axle center 132 return back to the optimum operation position; But after being squeezed, its oil film 121 need take a long time answer; Its axle center 132 returns back to the also increase relatively of time of optimum operation position relatively, and the time that noise and abrasion produce also can prolong relatively;
So known technology has disadvantage:
1. be easy to generate noise and vibration;
2. abrasion condition increases;
3. the time of noise generation is long;
4. influence working life.
