A limiting portion of the fixing part is arranged at the top end position of the shaft cylinder to be accommodated between the baring body and the shaft cylinder and fix the bearing body through the fixing portion of the fixing part, so that the usable space of the bearing body is effectively increased, and then the supporting performance of the bearing body is improved to reduce friction and abnormal noise, and the oil content of the bearing body can be improved and the lubrication degree can be maintained.
Description
Technical field
The utility model provides a kind of oil-impregnated bearing, refers to that especially a kind of supportive that improves is to reduce friction and to reduce oil-impregnated bearing and the oil-impregnated bearing fixed structure thereof that different sound produces.
Background technique
Press, because the progress in science and technology epoch, the operational effectiveness of electronic component is more and more higher, so that the requirement to the heat dissipation of electronic component also increases to heat-sink unit thereupon.
Be example with the host computer, the heat that its center of inside processing unit (CPU) produces 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, normally seal this host computer with the 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.
When operating, can produce high temperature again or as large scale electronic equipments such as general work station or servomechanisms, when if its operational temperature surpasses certain operating temperature, its high temperature then can influence work station, the task performance of main frames such as servomechanism, even influence work station, electronic component in the main frames such as servomechanism burns and then causes fault, especially stored database or archives are even more important in work station or the servomechanism, therefore it is of short duration when machine or damage and can cause follow-up bigger loss equally, so, work station, servomechanism is when setting up, and how heat dissipation problem makes temperature maintenance be considerable design link in operating temperature range for this.
Therefore dynamical heat-sink unit has been one of most important research and development emphasis of industrial circle today, be provided with heat-sink unit and by this heat-sink unit described electronic component dispelled the heat with the electronic component to this generation high temperature, described heat-sink unit is generally radiator or radiating fin correspondence and mixes a radiation fan and carry out heat radiation work, more and the exploitation of manufacturing with small volume along with electronic equipment walk always to see that the thickness degree of the radiation fan of its corresponding assembling also is more and more thinner.
See also shown in Figure 1, three-dimensional assembled sectional view for the radiation fan of known technology, described radiation fan 1 has a base 11 and a rotor set 12 and stator group 13, this base 11 has a beam barrel 111, and be formed with depression 112 places in these beam barrel 111 inside and be provided with a bearing 113, this bearing 113 utilizes an assembly parts 114 and a clasp 115 to be fixedly set on the described beam barrel 111, and its assembly parts 114 1 ends are arranged at the recess of its beam barrel 111, and the other end is arranged on the bearing 112, to fix its bearing on beam barrel, and this rotor set 12 has a wheel hub 121 and an axostylus axostyle 122, this axostylus axostyle 122 is inserted in aforementioned bearings 113, when described radiation fan 1 turns round, axostylus axostyle 123 relative these bearings 113 of this rotor set 12 rotate, but the thickness based on its radiation fan 1 is under the situation of fixed dimension, the gap of 121 of the assembly parts 114 of institute's combination and wheel hubs is too for a short time on its bearing 113 is easy to generate mutual friction situation and produces, therefore, for preventing phase mutual friction between its assembly parts and wheel hub, need dwindle the size of its bearing, but after its bearing size dwindles, support force between its axle center and bearing reduces, and the axle center has shaking phenomenon easily and produces different sound when rotating in bearing, more and bearing size dwindle its oil content and lubricity also relative minimizing.
