Description
Technical field
The present invention relates to a kind of fan, refer to especially a kind of fan that uses oil-impregnated bearing.
Background technique
Fan is a crucial constituent elements of Computerized heat dissipating system, and the service life, the reliability that improve fan are most important to ensureing the stable operation of computer system.And the bearing lubrication of fan plays a part very important to improving working life, the reduction noise of fan.
Existing fan adopts ball bearing or oil-impregnated bearing mostly, and wherein ball bearing belongs to rolling friction.This design friction factor is little, and rotating ratio is higher, thereby can bring better radiating effect, but that shortcoming is price is higher; Oil-impregnated bearing belongs to sliding friction, and noise is less, by absorbing and conserving lubricant oil, alleviates wearing and tearing, but along with the volatilization of dust fall and finish, can make bearing noise increase, and rotation speed of the fan slows down, and working life is long less than ball bearing.Therefore, the oil storage problem of oil-impregnated bearing is the emphasis problem of oil-impregnated bearing design field always.
Summary of the invention
The present invention proposes a kind of fan that uses oil-impregnated bearing, has solved in prior art the oil reserve of oil-impregnated bearing few, the problem that working life is short.
Technological scheme of the present invention is achieved in that
A kind of fan that uses oil-impregnated bearing, comprise casing, oil-impregnated bearing, sealing oil cap, stator, the rotor can relative stator rotating, casing comprises axle bed, described stator sleeve is peripheral at axle bed, described oil-impregnated bearing is contained in described axle bed, described sealing oil cap is positioned at oil-impregnated bearing bottom, lubricating fluid in described oil-impregnated bearing is sealed in described axle bed, described rotor comprises wheel hub, flabellum, the rotating shaft that is positioned at described oil-impregnated bearing and can rotates relative to oil-impregnated bearing, the described nave collar of taking turns is located at described stator periphery, described flabellum is located on wheel hub periphery, described rotating shaft is extended towards described axle bed from wheel hub central vertical, it is characterized in that, described oil-impregnated bearing excircle bottom is provided with several deep gouge.
Described oil-impregnated bearing is provided with two, and bottom is contained in axle bed in opposite directions, and the deep gouge of described two oil-impregnated bearings arranges in opposite directions, forms the accommodating cavity of lubricating fluid.
The excircle bottom of described oil-impregnated bearing is provided with several axial deep gouge.
Described deep gouge height is more than or equal to 1/3rd of oil-impregnated bearing height, is less than or equal to 2/3rds of oil-impregnated bearing height.
The described deep gouge degree of depth is more than or equal to 1/4th of oil-impregnated bearing radius, is less than or equal to 1/2nd of oil-impregnated bearing radius.
Compared with prior art, the invention has the advantages that, in the deep gouge that utilizes solidifying the putting forth effort of lubricant oil and be provided with in the excircle bottom of oil-impregnated bearing, contain the standby lubricant oil of part, when disappearance is separated out containing immersion oil in oil-impregnated bearing inside, standby lubricant oil supplements automatically, simultaneously because oil-impregnated bearing is provided with two, bottom is contained in axle bed in opposite directions, lubricating fluid in the deep gouge of two oil-impregnated bearings is circulated mutually, the oil storage space strengthening has directly increased oil reserve, can reach low cost, low noise, long-life object, expect that the life-span can reach 40,000 hours.
