Description
Technical field
The present invention relates to a kind of fan assembly of oil-impregnated bearing, particularly relate to a kind of oil-impregnated bearing and can effectively fix and the fan assembly can avoiding affecting because interfering close-fitting and some glue wayward the oil-impregnated bearing operated.
Background technique
Press, the use of electronics and IT products (such as: computer etc.) is increasingly universal and application is more extensive, because demand drives electronics and information industry technical development rapid, impelling electronic information towards performing the trend development that arithmetic speed promotes, access capability increases, causing the spare part in aforementioned electronic information products often to have high temperature to supervene in working at high speed.
For computer main, the heat that its internal central processing unit (CPU) produces accounts for major part, in addition, central processing unit when heat gradually rising can cause perform usefulness reduce, and when accumulation of heat is higher than its allowable limit, will force computer down, severe patient more may cause damage phenomenon; Further, for solving the problem of electromagenetic wave radiation, normally carry out this computer main closed with cabinet housing, 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 for the mode solving heat radiation is arrange radiator and radiation fan above it, some fins have been set up in the side of radiator, directly contact premise central processing unit with the surface of the opposite side of described radiator (not there is fin) and above-mentioned fin end can be conducted to make heat energy, and by heat loss through radiation with coordinate fan to force to drive air-flow to make the rapid dissipation of heat energy.
As Figure 1A, shown in 1B, for the three-dimensional assembled sectional view one of the oil-containing bearing heat radiation fan of prior art, two, this radiation fan 1 mainly has a fan base 11, this fan base 11 has a beam barrel 111, an oil-impregnated bearing 12 is provided with in this beam barrel 111, on this fan base 11, group is provided with an impeller 13 again, this impeller 13 outer ring is provided with multiple blade 131, and an axle center 132 is extended with in inner side, this axle center 132 is arranged in the axis hole 121 of described oil-impregnated bearing 12 and is detained knot location, and its radiation fan 1 when operating this axle center 132 stable rotation on oil-impregnated bearing 12, this oil-impregnated bearing 12 is fixedly installed in beam barrel 111, and its oil-impregnated bearing 12 has two with beam barrel 111 means of fixation, refer to Figure 1A, one means of fixation for carry out a glue processing procedure between this oil-impregnated bearing 12 and beam barrel 111, and when glue its glue material 14 likely via flowing to axis hole 121 position between this oil-impregnated bearing 12 and this beam barrel 111, and then when causing its axle center 132 to rotate in oil-impregnated bearing 12, have the stuck situation of different sound and axle center 132 to produce, refer to 1B figure again, another means of fixation is for mutually to interfere its oil-impregnated bearing 12 external diameter and beam barrel 111 internal diameter with close-fitting, but its axis hole 121 can be caused to inside contract during path interferometer close-fitting in its oil-impregnated bearing 12 external diameter and beam barrel 111 simultaneously and extrude described axle center 132, and then the normal assembly affecting its axle center 132 and axis hole 121 produces with the situation even causing axle center 132 stuck that operates.
Therefore prior art has its own shortcomings:
1. a wayward meeting of glue processing procedure is formed with different sound and causes axle center stuck;
2. interfere close-fitting extrusion axis podiod can ring normal assembly and cause axle center stuck.
Therefore, how will solve above-mentioned existing problem and disappearance, the inventor being this case studies the place, direction of improving with the anxious wish of relevant manufactures institute being engaged in the industry.
Summary of the invention
Therefore, for effectively solving the problem, main purpose of the present invention is providing a kind of oil-impregnated bearing effectively to fix and can avoid affecting the fan assembly of the oil-impregnated bearing operated because interfering close-fitting and some glue wayward.
Another object of the present invention is providing a kind of fan assembly that effectively can improve the oil-impregnated bearing in working life.
Another object of the present invention is providing a kind of fan assembly that effectively can reduce the oil-impregnated bearing of assembly cost.
For reaching above-mentioned object, the invention provides a kind of fan assembly of oil-impregnated bearing, comprising: a pedestal, the beam barrel having in a pipe and extended by middle pipe, this beam barrel has a bearing hole, and manages relative bearing hole position in this and have at least one end-to-end joint part; One oil-impregnated bearing, is arranged in described bearing hole, and this oil-impregnated bearing has at least one group connecting part butts up against described end-to-end joint part; Stator group, is sheathed on described beam barrel outer fix place.
