Description
本發明涉及一種軸承座，特別涉及一種成本較低且結構強度較強的軸承座及使用該軸承座的散熱風扇。 The invention relates to a bearing housing, in particular to a bearing housing with low cost and strong structural strength and a cooling fan using the bearing housing.
隨著電子資訊業不斷發展，電子元件運行頻率和速度亦在不斷提升。高頻高速將使電子元件產生的熱量越來越多，溫度亦越來越高，嚴重影響著電子元件運行時的性能和穩定性，為了確保電子元件能正常運行，必須及時排出電子元件運行所產生的大量熱量。 With the continuous development of the electronic information industry, the frequency and speed of electronic components are also constantly increasing. High-frequency high-speed will make more and more heat generated by electronic components, and the temperature is also higher and higher, which seriously affects the performance and stability of electronic components during operation. In order to ensure the normal operation of electronic components, electronic components must be discharged in time. A lot of heat is generated.
為此，業界通常在該等發熱電子元件表面安裝一散熱器，以輔助其散熱，而為使散熱器能夠及時地將熱量散發出去，另外需要在散熱器上安裝散熱風扇以提供一強制氣流，從而加快散熱器向外散熱。習知散熱風扇通常具有一軸承座，該軸承座包括一底座及設於該底座上的一軸承套。為了增加結構強度，所述軸承套通常由金屬製成，由金屬製造的軸承套再通過緊配合或點膠等方式固定於底座上。然而，該軸承套完全由金屬製造而成，會增加其製造成本。 To this end, the industry usually installs a heat sink on the surface of the heat-generating electronic components to assist in heat dissipation, and in order to enable the heat sink to dissipate heat in time, a heat-dissipating fan is required to be installed on the heat sink to provide a forced air flow. Thereby speeding up the heat dissipation of the heat sink. Conventional cooling fans generally have a bearing housing that includes a base and a bearing sleeve disposed on the base. In order to increase the structural strength, the bearing sleeve is usually made of metal, and the bearing sleeve made of metal is fixed to the base by tight fitting or dispensing. However, the bearing sleeve is completely made of metal, which increases its manufacturing cost.
有鑒於此，有必要提供一種結構強度較強且成本較低的軸承座及 使用該軸承座的散熱風扇。 In view of this, it is necessary to provide a bearing housing with strong structural strength and low cost. Use the cooling fan of the housing.
一種軸承座，包括底座及設於底座上的軸承套，該軸承套用於收容一軸承於其內，該軸承套包括外套及收容於外套內的內套，該外套由塑膠材料製造而成，該內套由金屬材料製造而成，該軸承收容於內套內。 A bearing housing includes a base and a bearing sleeve disposed on the base, the bearing sleeve is configured to receive a bearing therein, the bearing sleeve includes an outer sleeve and an inner sleeve received in the outer sleeve, the outer sleeve is made of a plastic material, The inner sleeve is made of a metal material, and the bearing is housed in the inner sleeve.
一種散熱風扇，包括軸承座、設於軸承座上的定子及轉子，該軸承座包括底座及設於底座上的軸承套，該定子套設於軸承套的外周面上，該軸承套內設有軸承，該轉子可旋轉地支撐設於軸承上，該軸承套包括外套及收容於外套內的內套，該外套由塑膠材料製造而成，該內套由金屬材料製造而成，該定子套設於外套的外周面上，該軸承收容於內套內。 A heat dissipation fan includes a bearing seat, a stator and a rotor disposed on the bearing housing, the bearing housing includes a base and a bearing sleeve disposed on the base, the stator is sleeved on an outer circumferential surface of the bearing sleeve, and the bearing sleeve is provided a bearing rotatably supported on the bearing, the bearing sleeve includes an outer sleeve and an inner sleeve received in the outer sleeve, the outer sleeve is made of a plastic material, and the inner sleeve is made of a metal material, and the inner sleeve is sleeved The bearing is received in the inner sleeve on the outer peripheral surface of the outer casing.
與習知技術相比，該散熱風扇由於軸承套由塑膠的外套包覆金屬的內套組合而成，既可以保證軸承套具有較高的結構強度，又相較於完全由金屬製造的軸承套節約成本。 Compared with the prior art, the heat dissipating fan is formed by combining the inner sleeve of the plastic sleeve with the metal sleeve, which can ensure the high structural strength of the bearing sleeve and the bearing sleeve made entirely of metal. save costs.

The bearing sleeve 13 includes a jacket 12 and an inner sleeve 14 disposed in the jacket 12. The outer casing 12 is cylindrical and is made of plastic. In this embodiment, the outer casing 12 and the base 11 are open Made by injection molding. The inner sleeve 14 is received within the outer casing 12 and can be covered by the outer casing 12 during injection molding of the outer casing 12. The inner sleeve 14 is cylindrical and is made of a metal material. A bearing 40 is disposed in the inner sleeve 14. The inner wall of the inner sleeve 14 is provided with a step 140 corresponding to the bottom end of the bearing 40 for supporting the bearing 40. The inner sleeve 14 has a higher height than the bearing 40 to prevent the lubricating oil in the bearing 40 from coming into direct contact with the outer casing 12 and being absorbed by the outer casing 12 of the plastic. Since the bearing sleeve 13 is composed of a plastic outer cover 12 coated with a metal inner sleeve 14, it can ensure that the bearing sleeve 13 has a high structural strength and is cost-effective compared to a bearing sleeve made entirely of metal.
所述定子20套設於軸承套13的外套12的外周緣，其包括一定子鐵芯21及纏繞於該定子鐵芯21上的線圈23。 The stator 20 is sleeved on the outer periphery of the outer casing 12 of the bearing sleeve 13 and includes a stator core 21 and a coil 23 wound around the stator core 21.
所述轉子30包括一輪轂31及環設於該輪轂31上的複數葉片33。該輪轂31包括一頂壁310及由該頂壁310的周緣向下延伸形成的一環形壁312，該頂壁310與該環形壁312合圍成一收容定子20的收容空間。該頂壁310的中心向軸承套13所在方向延伸形成一轉軸32，所述轉子30通過轉軸32裝配在軸承40中從而可旋轉地安裝於底座11上。所述環形壁312內貼設一磁鐵環34，所述轉子30通過磁鐵環34與定子20的相互作用而旋轉。 The rotor 30 includes a hub 31 and a plurality of blades 33 ringed on the hub 31. The hub 31 includes a top wall 310 and an annular wall 312 extending downward from the periphery of the top wall 310. The top wall 310 and the annular wall 312 define a receiving space for receiving the stator 20. The center of the top wall 310 extends in the direction of the bearing sleeve 13 to form a rotating shaft 32. The rotor 30 is mounted in the bearing 40 through the rotating shaft 32 so as to be rotatably mounted on the base 11. A magnet ring 34 is attached to the annular wall 312, and the rotor 30 is rotated by the interaction of the magnet ring 34 and the stator 20.
圖2所示為本發明散熱風扇100a的第二實施例，本實施例與前一實施例的不同之處在於：所述底座11a可由金屬或其他材料製造而成，該底座11a對應外套12的位置向上延伸有延伸部110，所述外套12在注塑成型的過程中與底座11a的延伸部110相連接而固定。 2 is a second embodiment of the heat dissipation fan 100a of the present invention. The difference between this embodiment and the previous embodiment is that the base 11a can be made of metal or other materials, and the base 11a corresponds to the outer casing 12. Extending upwardly is an extension 110 that is secured to the extension 110 of the base 11a during injection molding.
