Abstract
The invention discloses a bearing seat, comprising a base and a bearing sleeve arranged on the base, wherein the bearing sleeve is used for containing a bearing; the bearing sleeve comprises an outer sleeve and an inner sleeve contained in the outer sleeve; the outer sleeve is made of plastic materials; the inner sleeve is made of metal materials; the bearing is contained in the inner sleeve; and the bearing sleeve is formed by using the plastic outer sleeve to coat the metal inner sleeve, and can ensure that the bearing sleeve has higher structural strength and lower cost. The invention also provides a radiating fan using the bearing seat.
Description
Technical field
The present invention relates to a kind of bearing support, the bearing support that particularly a kind of cost is lower and structural strength is stronger and use the radiation fan of this bearing support.
Background technique
Along with the electronic and information industry development, electronic component operation frequency and speed are also in continuous lifting.The heat that high-frequency high-speed will make electronic component produce is more and more, temperature is also more and more higher, performance and stability when having a strong impact on the electronic component operation can normally be moved in order to ensure electronic component, must in time discharge the amount of heat that the electronic component operation produces.
For this reason, industry is installed a radiator on these heat-generating electronic elements surfaces usually, with auxiliary its heat radiation, and for radiator can be gone out dissipation of heat in time, need to radiation fan be installed so that a forced draft to be provided at radiator in addition, outwards dispel the heat thereby accelerate radiator.Existing radiation fan has a bearing support usually, and this bearing support comprises a base and is located at a bearing housing on this base.In order to increase structural strength, described bearing housing is made of metal usually, is fixed on the base by modes such as drive fit or some glue by the bearing housing of metal manufacturing again.Yet this bearing housing is formed by the metal manufacturing fully, can increase its manufacture cost.
Summary of the invention
In view of this, the radiation fan that is necessary to provide the stronger and lower-cost bearing support of a kind of structural strength and uses this bearing support.
A kind of bearing support comprises base and is located at bearing housing on the base that this bearing housing is used for accommodating a bearing in the inner, this bearing housing comprises overcoat and is contained in the interior inner sleeve of overcoat, this overcoat is formed by the plastic material manufacturing, and this inner sleeve is formed by the metallic material manufacturing, and this bearing is contained in the inner sleeve.
A kind of radiation fan, comprise bearing support, be located at stator and rotor on the bearing support, this bearing support comprises base and is located at bearing housing on the base that this stator sleeve is located on the outer circumferential face of bearing housing, is provided with bearing in this bearing housing, this rotor rotatably props up and stays on the bearing, this bearing housing comprises overcoat and is contained in inner sleeve in the overcoat, and this overcoat is formed by the plastic material manufacturing, and this inner sleeve is formed by the metallic material manufacturing, this stator sleeve is located on the outer circumferential face of overcoat, and this bearing is contained in the inner sleeve.
Compared with prior art, this radiation fan both can guarantee that owing to the inner sleeve of bearing housing by the overcoat clad metal of plastic cement combines bearing housing has higher structural strength, saves cost compared to the bearing housing of being made by metal fully again.

Following embodiment further specifies the present invention in connection with above-mentioned accompanying drawing.
Embodiment
As shown in Figure 1, this radiation fan 100 comprises a bearing support 10, is located at a stator 20 and a rotor 30 on this bearing support 10.
This bearing support 10 comprises a base 11 and is located at a bearing housing 13 on the base 11.This bearing housing 13 comprises an overcoat 12 and is located at a inner sleeve 14 in this overcoat 12.This overcoat 12 is cylindric, and it is formed by the plastic cement manufacturing.In the present embodiment, this overcoat 12 can be made into integration by injection molding with base 11.This inner sleeve 14 is contained in the overcoat 12, can be coated wherein by described overcoat 12 in the process of overcoat 12 molding and forming.Described inner sleeve 14 is cylindric, and it is formed by the metallic material manufacturing.Be provided with a bearing 40 in this inner sleeve 14, the bottom of the corresponding bearing 40 of the inwall of described inner sleeve 14 is provided with a step 140, to be used for spring bearing 40.The height of described inner sleeve 14 is higher than bearing 40, to prevent that lubricant oil in the bearing 40 from directly contacting with overcoat 12 and by overcoat 12 absorptions of plastic cement.Because bearing housing 13 is combined by the inner sleeve 14 of overcoat 12 clad metals of plastic cement, both can guarantee that bearing housing 13 has higher structural strength, save cost compared to the bearing housing of being made by metal fully again.
Described stator 20 is sheathed on the outer periphery of the overcoat 12 of bearing housing 13, and it comprises a stator iron core 21 and is wound in coil 23 on this stator iron core 21.
Described rotor 30 comprises a wheel hub 31 and is located on some blades 33 on this wheel hub 31.This wheel hub 31 comprises a roof 310 and an annular wall 312 that is extended to form by the periphery of this roof 310 downwards, and this roof 310 and this annular wall 312 are encircled into the containing space of a housing stator 20.The middle mind-set bearing housing 13 place directions of this roof 310 extend to form a rotating shaft 32, thereby described rotor 30 is assemblied in the bearing 40 by rotating shaft 32 and is rotatably mounted on the base 11.The magnet ring 34 that is sticked in the described annular wall 312, described rotor 30 rotates by magnet ring 34 and the interaction of stator 20.
Figure 2 shows that the second embodiment of radiation fan 100a of the present invention, present embodiment and last embodiment's difference is: described base 11a can be formed by metal or other materials manufacturing, the position of the corresponding overcoat 12 of this base 11a has extended upward extension part 110, and described overcoat 12 is connected with the extension part 110 of base 11a in the process of molding and forming and fixes.
Be understandable that, for the person of ordinary skill of the art, can make change and the distortion that other various pictures are answered by technical conceive according to the present invention, and all these change the protection domain that all should belong to claim of the present invention with distortion.
