Description
Technical field
The present invention provides a kind of oiliness bearing, espespecially a kind of to improve supportive to reduce friction and reduce what abnormal sound produced
Oiliness bearing and its oiliness bearing fixed structure.
Background technology
Press, due to the progress of Technology Times, the operational effectiveness of electronic component is higher and higher, so as to heat-sink unit to electricity
The requirement of the heat dissipation of subcomponent is consequently increased.
By taking host computer as an example, heat caused by its internal central processing unit (CPU) accounts for major part, in addition, central
Processing unit can cause to perform efficiency reduction when heat gradually rises, and when accumulation of heat is higher than its allowable limit, it will compel
Computer is set to work as machine, severe patient is more likely to cause to damage phenomenon;Also, to solve the problems, such as electromagenetic wave radiation, typically with machine
Tank shell closes the host computer, so that how by central processing unit and the thermal energy of other fever spare parts (or element)
Quick export, becomes an important topic.
Again or such as general work station or servomechanism large scale electronic equipment can produce high temperature in running, if its operational temperature
During more than certain operating temperature, its high temperature can then influence the task performance of the hosts such as work station, servomechanism, even influence work
Stand, the electronic component in the host such as servomechanism burns and in turn results in failure, stored data especially in work station or servomechanism
Storehouse or archives are even more important, therefore its of short duration loss that follow-up bigger can be equally caused when machine or damage, therefore, work station,
For servomechanism when setting up, how heat dissipation problem makes temperature maintain in operating temperature range is considerable design link for this.
Therefore dynamical heat-sink unit has been one of the most important Research Emphasis of industrial circle today, with high to the generation
The electronic component of temperature is provided with heat-sink unit and is radiated by the heat-sink unit to the electronic component, the heat-sink unit
Usually radiator or radiating fin correspondence mix a radiator fan and carry out heat dissipation work, more and as electronic device is with small size
The exploitation of the manufacturing, which is walked, always to be seen, it is also more and more thinner that it, which corresponds to the thickness degree of the radiator fan of assembling,.
Refering to Figure 1, the three-dimensional assembled sectional view of the radiator fan for known technology, the radiator fan 1 has
One base 11 and a rotor set 12 and stator group 13, which has a beam barrel 111, and is internally formed in the beam barrel 111
Have at a depression 112 and be provided with a bearing 113, which is fixedly installed on using a sub-assembly 114 and a retaining ring 115
On the beam barrel 111, and its 114 one end of sub-assembly is arranged at the recess of its beam barrel 111, and the other end is arranged in bearing 112
On, to fix its bearing on beam barrel, and the rotor set 12 has a wheel hub 121 and an axostylus axostyle 122, which is inserted in
Aforementioned bearings 113, when the radiator fan 1 operates, the axostylus axostyle 123 of the rotor set 12 is rotated relative to the bearing 113, but base
In the case that the thickness of its radiator fan 1 is fixed dimension, between the sub-assembly 114 and wheel hub 121 that are combined on its bearing 113
Gap too it is small easily produce phase mutual friction situation produce, therefore, to prevent its sub-assembly and phase mutual friction between wheel hub, need to contract
The size of its small bearing, but after the diminution of its bearing size, the support force between its axle center and bearing reduces, and axle center is in bearing turns
Easily there is shaking phenomenon when dynamic and produce abnormal sound, more and bearing size reduces its oil content and lubricity also opposite reduction.
Therefore known technology has the disadvantage that:
1. the support force between axle center and bearing reduces;
2. there is shaking phenomenon and produce abnormal sound;
Reduced 3. oil content is opposite with lubricity.
Therefore, its intelligence is exhausted then, is concentrated on studies in view of every shortcoming, the inventor of this case derived from above-mentioned utility
Improvement is innovated, successfully this part " oiliness bearing and its oiliness bearing fixed structure " a case is completed in research and development finally, actually a tool
The invention that effect is promoted.
The content of the invention
For this reason, the shortcomings that to solve above-mentioned known technology, it is a primary object of the present invention to provide one kind can improve supportive
To reduce friction and reduce the oiliness bearing and its oiliness bearing fixed structure of abnormal sound generation.
The secondary objective of the present invention is providing a kind of oiliness bearing and its oil-containing for improving oil content and maintaining lubricity
Bearing fixing structure.
In order to achieve the above object, the present invention provides a kind of oiliness bearing.Including:One bearing body, the bearing body have
One top and a bottom, have extended to form between the top and bottom formed with a side and an axis hole, the side toward axis hole is universal
One placing part.
The width of the placing part is less than the width of the bottom.
Formed with a butting section between the placing part and top.
The length for being shorter in length than the axis hole of the butting section.
The present invention additionally provides a kind of oiliness bearing fixed structure, including:One pedestal, a bearing body and at least one fix
Part, the pedestal side extend a beam barrel, and the beam barrel has a bearing hole and a fixing end and a top, and the fixing end is with being somebody's turn to do
Pedestal connects, and the bearing body is arranged in the bearing hole of the beam barrel, and the bearing body has a top and a bottom, should
Formed with a side and an axis hole between top and bottom, beam barrel described in the contact aside and extend to form one toward axis hole is universal and held
Put portion, formed with an accommodating space between the placing part and beam barrel, and the fixing piece formed with a fixed part and a limiting section, this is solid
Determine portion to be arranged in the accommodating space and contradict the placing part, and the limiting section is arranged at the apical position of the beam barrel.
Further included a rotor set, which has multiple blades and an axle center, the axle center be hubbed in the axis hole and
Wear the bearing.
The fixing piece is shaped by material hot melt and forms the fixed part and limiting section.
Formed with a butting section between the placing part and top, and formed with described between the butting section and placing part and beam barrel
Accommodating space.
The length for being shorter in length than the axis hole of the butting section.
The width of the placing part is less than the width of the bottom.
A stator group is further included, which is sheathed on the outside of foregoing beam barrel.
The pedestal 3 is metal material or plastic material.
The fixing piece heats shaping by the beam barrel of the pedestal.
Whereby, it is placed in by the fixed part of the fixing piece between bearing body and beam barrel and fixes the bearing body,
To be effectively increased the usable space of bearing body, and then the supportive for improving bearing body is produced with reducing friction and reducing abnormal sound
The effect of raw, and bearing body oil content can be improved with maintaining lubricity;Therefore the present invention has following advantages:
1. improve the support force between axle center and bearing;
Produced 2. reducing shaking phenomenon and reducing abnormal sound;
