Fan is a key building block of Computerized heat dissipating system, and the service life of raising fan, reliability are to ensureing
The stable operation of computer system is most important.And the bearing lubrication of fan is played to improving the service life of fan, reducing noise
Very important effect.
Mostly using ball bearing or oiliness bearing, wherein ball bearing belongs to rolling friction to existing fan.This set
Meter coefficient of friction is little, and rotating ratio is higher, thus can bring more preferable radiating effect, but has the disadvantage that price is higher；Oiliness bearing
Belong to sliding friction, noise is less, by absorbing and conserving lubricating oil, mitigate abrasion, but the volatilization with dust fall and oil preparation, meeting
Bearing noise is made to increase, rotation speed of the fan slows down, and service life is long without ball bearing.Therefore, the oil storage problem one of oiliness bearing
It is directly the emphasis problem of oiliness bearing design field.
Content of the invention
The present invention proposes a kind of fan of use oiliness bearing, and the oil reserve for solving oiliness bearing in prior art is few,
The short problem of service life.
The technical scheme is that and be achieved in that：
A kind of fan of use oiliness bearing, including casing, oiliness bearing, is sealed oil cap, stator, can be turned with relative stator
Dynamic rotor, casing include axle bed, and in axle bed periphery, the oiliness bearing is contained in the axle bed stator sleeve, described
Sealing oil cap is located at oiliness bearing bottom, the lubricating fluid in the oiliness bearing is sealed in the axle bed, the rotor
Including wheel hub, flabellum, the rotating shaft for being located in the oiliness bearing and can rotating relative to oiliness bearing, the wheel nave collar is located at described
Stator peripheral, the flabellum are located on wheel hub periphery, and from hub centre, vertically the axle bed extends for the rotating shaft, its feature
It is, described oiliness bearing excircle bottom is provided with several deep gouge.
Described oiliness bearing is provided with two, and bottom is contained in axle bed in opposite directions, the deep gouge phase of described two oiliness bearings
To setting, the accommodating cavity of lubricating fluid is constituted.
The excircle bottom of described oiliness bearing is provided with several axial deep gouge.
Described deep gouge is highly more than or equal to 1/3rd of oiliness bearing height, less than or equal to the three of oiliness bearing height
/ bis-.
A quarter of the described deep gouge depth more than or equal to oiliness bearing radius, less than or equal to the two of oiliness bearing radius
/ mono-.
Compared with prior art, it is an advantage of the current invention that using lubricating oil solidifying putting forth effort and in the cylindrical of oiliness bearing
The standby lubricating oil in part is contained in the deep gouge that all bottoms are provided with, when separating out disappearance containing immersion oil inside oiliness bearing, standby
Lubricating oil is automatically replenished, simultaneously because oiliness bearing is provided with two, bottom is contained in axle bed in opposite directions, makes two oiliness bearings
Lubricating fluid in deep gouge mutually circulates, and the oil storage space of increasing directly increases oil reserve, can reach low cost, low noise,
Long-life purpose, expects the life-span up to 40,000 hours.
