Abstract
The utility model relates to a radiation fan, particularly a long service life fan apparatus with a lubricating axis structure, which comprises a frame (3), a fan blade (1), an electric driving assembly (5) and an axis (2). The utility model is characterized in that a spiral groove (22) is arranged on the axis (2). The long service life fan apparatus adopts the axis structure of the spiral groove and can stop that oil flows to the fan blade direction along the surface of the axis, and consequently, the running off of the oil can be stopped, the favorable lubrication action for the axis can be retained, and the service life of the fan can be extended.
Description
Technical field
The utility model relates to a kind of radiation fan, relates in particular to a kind of electronic parts and components radiation fan.
Prior art
Because electronic parts and components can produce a large amount of heats when operation, too high temperature can influence the proper functioning of electronic parts and components, therefore need carry out forced heat radiation at electronic parts and components; Be on electronic parts and components, to establish a radiator to dispel the heat generally speaking.At present, the fan producer rotational structure that in the fan of producing, generally adopts oil-impregnated bearing to cooperate with the axle center.As shown in Figure 5, oil-impregnated bearing adopts outer lubricating oil filling or utilizes the oil of depositing in advance in the oil-impregnated bearing to lubricate; Fan axial center when rotated, the temperature at axle center place raises, oil viscosity diminishes; The oil 41 that the while oil-impregnated bearing is 4 li also can flow to 2 places, axle center, and the oil 91,92 on surface, axle center can bottom 24 and top 21 directions along surface 23, axle center toward axle center 2 flow; The bottom 24 in axle center 2 is not owing to be connected with other exposed part, and therefore 92 of oil can arrive 2 bottoms 24, axle center, and can not run off; Oil 91 can flow to the axle housing surface 11 of flabellum along surface, axle center 23, be lost by action of centrifugal force, so the oil at oil-impregnated bearing and axle center place will be lost gradually, lubrication weakens gradually to disappearance, the fan noise that lacks effectively lubricating increases, and also shorten greatly working life.
Summary of the invention
The purpose of this utility model is to overcome the above-mentioned deficiency of prior art and proposes a kind of long lifetime fan assembly with lubricating axis structure, adopt spiral chute axle center structure, can stop oil to flow toward the flabellum direction along the surface, axle center, thereby stop oil to run off, the lubrication that maintenance is good to the axle center, the working life of prolongation fan.
The purpose of this utility model can reach by adopting following technical measures:
Design, a kind of long lifetime fan assembly with lubricating axis structure of manufacturing comprise framework, flabellum, power drive assemblies and axle center, and especially described axle center is provided with spiral chute.

Embodiment
Below in conjunction with accompanying drawing in detail embodiment of the present utility model is described in detail.
A kind of long lifetime fan assembly with lubricating axis structure comprises framework 3, flabellum 1, power drive assemblies 5 and axle center 2; Especially described axle center 2 is provided with spiral chute 22.Axle center 2 is fixed on the flabellum 1 and oil-impregnated bearing 4 is assembled into a rotating mechanism; Oil-impregnated bearing 4 is fixed on the framework 3; Spiral chute 22 parts on the axle center are in oil-impregnated bearing 4, and a part is exposed at bearing 4 outsides.When flabellum rotated counterclockwise, the oil 41 of oil-impregnated bearing 4 flowed to surface, axle center 23; Because the effect of spiral chute 22, the too much oil 28 on 2 surfaces 23, axle center will flow to bottom, axle center 24, and can not flow to flabellum 1.The seal space 8 that 24 places, bottom, axle center have framework 3 and oil cap 6 to form is marked with a certain amount of lubricant oil in advance in seal space 8, enable in time to replenish the lubricant oil of 4 li of oil-impregnated bearings; Therefore flow to oil 28 meetings of bottom 24 and the oil of seal space and converge, can not run off; The oil mass that so just can keep lubricant oil guarantees lubrication effect, lowers the working life of fan work noise, prolongation fan.
Described spiral chute (22) entire length is not more than 9/10ths of described axle center (2) length.When Fan axial center rotates, the oil on its surface can be along surface, axle center 23 respectively to the bottom 24 and the top 21 directions stream in axle center; The bottom 24 in axle center 2 is owing to 8 li of the seal spacies that is positioned at framework 3 and oil cap 6 formation, and therefore oil only can arrive 2 bottoms 24, axle center, and can not run off; And the oil that flows to the flabellum direction along the surface, axle center really need prevent to run off, spiral chute 22 rotations are to the active force of the formation of the oil on its surface 23 to bottom, axle center 24 directions, this active force interception also promotes the surface 23 that oil continues to stay axle center 2, and unnecessary oil can flow to bottom, axle center 24 along surface, axle center 23 and store.So spiral chute 22 entire length are not more than the function that 9/10ths of axle center 2 length can realize protecting oil to some extent; The spiral chute Design of length can be adjusted according to concrete fan assembly and Environmental Conditions.
Described spiral chute 22 is left-handed rotation.In some specific embodiments, the flabellum of fan is what turn clockwise, and the spiral chute of its Fan axial center should be left-handed rotation accordingly; When flabellum rotated like this, spiral chute 22 will be to the active force of the generation of the oil on its surface 23 to bottom, axle center 24 directions.
In other embodiment, described spiral chute 22 is the dextrad rotation, and the flabellum of fan is what be rotated counterclockwise, and the spiral chute of its Fan axial center should be the dextrad rotation accordingly; When flabellum rotated like this, spiral chute 22 also can be to the active force of the generation of the oil on its surface 23 to bottom, axle center 24 directions.
The pitch of described spiral chute 22 is greater than these spiral chute 22 groove widths.To guarantee between spiral chute enough spacings being arranged, keep the effect of oil return.
In different embodiments, the section of described spiral chute 22 can be triangle, also can be the garden arc.Decide on the size of the Fan axial center diameter of different wind-force and the convenience of processing.
