Description of the invention: [Technical field to which the invention belongs] The present invention relates to a wind bank!杳, 杳σ » θ is not a wind motor, especially a fan motor with stable speed, no oil leakage, and easy manufacturing. [Prior Art] As shown in Figs. 1, 2, and 3, a conventional fan motor includes a centrally penetrating housing 11, a stator 12, and a rotor 13. The casing 11 includes a foundation. The earth 111, a port, an axis z, and a mounting hole 112 of the base wall (1), extending from the base wall (1) along the axis z a housing (1), a chamber ι4 defined by the base wall (1) and the frame 113, an oil seal 115 sealed from the outside of the chamber 114 along the axis z, and attached to the mounting hole , The label ΐ6 on the outside of the oil seal cover 115. The «oil seal 115' is used to close the mounting aperture 12 to prevent leakage of added lubricant therein. The label 116 can assist in further enclosing the exterior of the oil seal 115 to increase the effectiveness of the seal. The stator 12 includes a shaft tube 121 coupled to the mounting hole 112, a set of bearings 122 disposed in the shaft member 121, a plurality of windings 123 disposed on the outer circumferential surface of the shaft tube ΐ2, and an electrical connection thereto. Circuit board 124 of winding 123. The bearing 122 has a shaft hole 125 that runs up and down along the axis z. The rotor 13 includes a rotating plate 131 facing the base wall lu, a frame plate 132 extending from the periphery of the rotating plate 131 and surrounding the windings 123, and extending from the rotating plate 131 along the axis z and passing through An axis 133 extending from the shaft hole 125, and a plurality of washers 134 and 260 respectively disposed on the upper and lower sides of the bearing 122 and sleeved at 128310° 1 of the shaft 122 are respectively located on the upper and lower sides of the bearing 122 The oil ring 135, _ is set on the 5th axis to 133, and is set on the shaft. The bottom buckle I%, the plurality of magnetic blocks 137' disposed on the inner circumferential surface of the frame plate 132 and corresponding to the windings 123, and the plurality of blades 138 136 disposed on the outer circumferential surface of the frame 132 are

卡設於該軸，c; 133周㈣—扣環槽139巾，藉此可以使招該軸心133在旋轉時能限制於該軸孔125中，以及不會孝該轉子13整組脫離出該軸承122的情形產生。 a、的兩側， 135及華該等油圈135及華司134是位於該軸孔125 製造時該軸孔125内有添加有潤滑油，該等油圈司134的用途是作為防止潤滑油漏出而設計。但是缺點產生，以致於有改善的必亜，士处 u 乃人σ幻必要，才能提供更理想的製造品質及使用效果，諸如：以上，為傳統風扇馬達的主要結構，雖然行之多年，由於結構上仍有缺憾，所以使用、製造方面還有許多 1·由於上述結構必須使用該油封蓋115、該等華司 ’及該等油圈135等多數構件，且該等構件的尺寸都相當微小，不易導入自動化製程，所以會造成製造複雜及材料成本增加，以及容易磨損，造成風扇卡死不轉之品質瑕疵。 2·該軸心133必須穿伸過該軸孔125處，所以長度會較該框板132要長，而在運轉時因重心高也就容易文到该框板132與該等扇葉138的重力影響，使得 6 1283100 :走㈣心不容易集中在該軸心、⑴4,於是，會有 =不平料擺的情形發生，又因為該轴心133與日士 7 in疋呈圓周面的大面積接觸，所以不但旋轉丁有偏擺現象’還會因為偏擺而造成更多摩柊，導致噪音、磨損、高溫、轉速降低等情形也因：增加〇 3.長期運轉下’由於該轴心133與軸纟122的摩擦合產生高溫’以致於在材料反覆驗冷縮時就容易有縫隙產生，尤其是以該油封蓋115冑最容易產生縫隙，、即使貼有該標籤116密封，長期運轉也會因為縫隙而造成漏油的現象。 4·該心133的長度較長’扭力較小，又與該轴承 122有大面積接觸，所以無法添加濃稠度較高的潤 /月油（例如牛油），只能採用流動性較高的油料，而當縫隙產生時，流動性較高的油料也造成更嚴重的漏油現象。 5·另外當縫隙產生時，該軸孔125處就有對流產生，於是空氣中的塵埃會侵入到該軸承122處，導致運轉的更不順暢，不但減少使用的壽命，還增加噪音、轉速下降及故障。 6.由於該扣環136是C形結構（如圖3所示），並且非固定於該軸承122的端部，而只是卡設於該軸心 133的扣環槽139中，於是容易與該軸心133呈同步旋轉，所以也造成更多摩擦及噪音，又因為該扣 7 1283100 環136的開口在組裝及旋轉時容易引發變形，所以長期運轉下常會導致脫落，進而影響運轉造成故障The card is disposed on the shaft, c; 133 weeks (four) - the buckle groove 139 towel, whereby the axis 133 can be restrained in the shaft hole 125 when rotating, and the rotor 13 is not detached from the whole group The situation of the bearing 122 is created. The oil grooves 135 and the washers 134 of the 135 and the Huashi 134 are located in the shaft hole 125 when the shaft hole 125 is manufactured, and the lubricating oil is added to the shaft hole 125. The use of the oil ring 134 is used as a lubricating oil. Designed to leak out. However, the shortcomings have arisen, so that there is a need for improvement. It is necessary for people to provide more ideal manufacturing quality and use effects, such as: Above, the main structure of the traditional fan motor, although it has been for many years, due to There are still many defects in the structure, so there are many uses and manufacturing. 1. Due to the above structure, it is necessary to use the oil seal cover 115, the washers and the oil retainers 135 and the like, and the dimensions of the members are relatively small. It is not easy to introduce an automated process, so it will result in complicated manufacturing and increased material costs, as well as easy wear and tear, resulting in a quality of the fan stuck. 2. The shaft 133 must pass through the shaft hole 125, so the length is longer than the frame plate 132, and it is easy to reach the frame plate 132 and the blades 138 due to the high center of gravity during operation. The influence of gravity makes 6 1283100: the (four) heart is not easy to concentrate on the axis, (1) 4, so there will be a situation of = unevenness, and because the axis 133 and the Japanese in 7 in 疋 are large areas of the circumference Contact, so not only the rotation of the Ding has a yaw phenomenon, but also because of the yaw caused by more friction, resulting in noise, wear, high temperature, reduced speed, etc. also caused by: increase 〇 3. Long-term operation under the axis 133 The friction with the shaft 122 produces a high temperature so that a gap is easily generated when the material is repeatedly tested for cold shrinkage, in particular, the oil seal cover 115 is most likely to produce a gap, even if the label 116 is sealed, long-term operation is also performed. It will cause oil leakage due to the gap. 4. The length of the core 133 is long, the torque is small, and the bearing 122 has a large area of contact, so it is impossible to add a thicker/smoky oil (such as butter), and only a higher fluidity can be used. Oil, and when the gap is generated, the oil with higher fluidity also causes more serious oil leakage. 5. In addition, when the gap is generated, convection occurs at the shaft hole 125, so that dust in the air will invade the bearing 122, resulting in a smoother operation, which not only reduces the service life, but also increases noise and speed. And failure. 6. Since the buckle 136 is of a C-shaped structure (as shown in FIG. 3) and is not fixed to the end of the bearing 122, but is only locked in the buckle groove 139 of the shaft 133, it is easy to The shaft 133 rotates synchronously, so it also causes more friction and noise, and the opening of the ring 136 of the buckle 7 1283100 is easily deformed during assembly and rotation, so the long-term operation often causes the falling off, which may affect the operation and cause malfunction.

7·該轴承122裝入該軸f 121定位時，因為底部是鏤空無法固定支樓’ Μ裝上不具有防呆功能，所以製造時必須依賴精密量測工具做^時量測，以確保= 轴承m與軸線ζ平行而不會偏移，如此—來二旦發現定位狀態不正確時，就必須將整批大量的不良品重新加工，甚至報廢，於是就會造成材料、工時的重大損失’也可能冒著不良品外流出貨的疑慮與風險。 8.如果是使用進口的滾珠轴承（BaU Bearmg)雖然產 2價值較佳’但必須全數依賴國外進口，不只是收貨期間存有風險’品質也難要求及掌控，而且價格高出一般套筒軸承（Sleeve Bearing)好幾十倍，所以產品毫無競爭力。7. When the bearing 122 is installed in the shaft f 121, because the bottom is hollow, the branch cannot be fixed. The armor does not have the foolproof function. Therefore, it must rely on the precision measuring tool to make the measurement when manufacturing to ensure = The bearing m is parallel to the axis 而 without offset, so that when the positioning state is found to be incorrect, the entire batch of defective products must be reprocessed or even scrapped, thus causing significant loss of materials and working hours. 'It may also be risky and risky to ship out of bad goods. 8. If you use imported ball bearings (BaU Bearmg), although the value of production 2 is better, but you must rely on foreign imports, not only the risk during the receipt of goods, the quality is difficult to demand and control, and the price is higher than the general set. Sleeve Bearing is dozens of times, so the product is not competitive.

也就疋该軸心43是位於該框板42内部（形成短軸心結構），所以該轉子40整體的重心低且能朝向該軸心43集中，而達到在高速旋轉下依然能夠穩定旋轉，也不偏擺晃動的絕佳成果，另外，該軸承24底面243的圓弧面設計也能導引該軸心轉動，使其不易朝旁側偏移，能加強該轉子4〇整體旋轉的穩定效果。 4·由於該軸心43與軸承24之底面243的接觸面積小That is, the axis 43 is located inside the frame plate 42 (forming a short-axis structure), so that the center of gravity of the rotor 40 as a whole is low and can be concentrated toward the axis 43 to achieve stable rotation under high-speed rotation. It is also an excellent result of not swaying. In addition, the circular arc surface design of the bottom surface 243 of the bearing 24 can also guide the rotation of the shaft center, so that it is less likely to be offset toward the side, and the stability of the overall rotation of the rotor 4 can be enhanced. . 4. The contact area between the shaft 43 and the bottom surface 243 of the bearing 24 is small.

，且該軸心43長度短，重心低且能更集中在該軸心 43處，所以該轉子40的扭力更高，適合添加高濃稠度的潤滑油（例如牛油），又因為油料的濃稠度很咼，且具有難以流動的特性，所以就能達到不漏油的效果。 ^又私20的基壁21、該轴承柱211、該軸承疋形成封閉結構，沒有任何縫隙及㈣π，所以潤 …去外漏滲出，並且當該轉子4〇轉動時，該耜 f5無去开> 成空氣對流，所以灰塵就不會侵入 13 1283100 達到能增加使用壽命、維持長時間良好運轉的使用效果。 6·該扣環50是封閉環形，所以即使該軸心43有偏擺產生而摩擦該扣環50，也不容易有變形脫落及同步轉動的情形發生’而能維持長時間的使用效果 7·該套環60可緊迫該扣環50與該軸承24連結，所以能避免該扣環50偏移而與軸心43摩擦，達到定位該扣環50減少摩擦噪音、摩擦生熱的功效。The axial center 43 has a short length, a low center of gravity, and can be concentrated at the axial center 43. Therefore, the rotor 40 has a higher torque, and is suitable for adding a high-concentration lubricating oil (such as butter) and because of the thick oil. The consistency is very sturdy and has the characteristics of being difficult to flow, so that the effect of no oil leakage can be achieved. ^ The base wall 21 of the private 20, the bearing column 211, the bearing 疋 form a closed structure, without any gap and (4) π, so that the outer leakage leaks out, and when the rotor 4 turns, the 耜f5 does not open > Air convection, so dust will not invade 13 1283100 to achieve the effect of increasing the service life and maintaining long-term good operation. 6. The buckle 50 is a closed loop. Therefore, even if the shaft 43 is yawed and rubbed against the buckle 50, it is not easy to have deformation and fall off and synchronous rotation occurs, and the long-term use effect can be maintained. The collar 60 can tightly connect the buckle 50 to the bearing 24, so that the buckle 50 can be prevented from being offset and rubbed against the shaft 43 to achieve the effect of positioning the buckle 50 to reduce friction noise and friction heat generation.

8 ·製造時，該軸心43只要對準於該扣環5〇的令心孔 51處，再透過施加重力緊迫入該扣環5〇之令，就可以完成與該殼體20、該定子30的安裝工作，所以具有製造容易導入自動化，簡潔迅速且省力省時又邊提咼良率的使用效果。8 · At the time of manufacture, the shaft 43 is aligned with the center hole 51 of the buckle 5 ,, and then pressed into the buckle 5 by applying gravity, and the housing 20 and the stator can be completed. 30 installation work, so it is easy to import and manufacture, simple, quick, labor-saving and time-saving, while improving the yield.

9·"亥軸承24裝置在固定高度的軸承柱211上，組裝上具有防呆功能，所以定位準確可不必依靠或使用任何里測工具額外去進行隨時测量的動作，不只省掉里測工日守，同時也不會發生類似傳統結構會產生定位偏移而形成之品質不良問題。 1〇·^發明該套筒轴承24封閉、該軸心43短的結構品 2可媳美滚珠軸承（Ball Bearing)，且成本低廉，合易5丁購與製造，所以產品極具競爭力。是，由上、十、…、提升 ^ ^ g兄明可知，本發明較傳統的風扇馬達能心开相當鬲的使，，傕Ρ ^ 放果，亚能同時兼顧製造與品質的進步 1更伸本發明更舍右古 ^ 田 ν出同業產品的產業競爭優勢。 14 1283100 如圖9、1G所示，以下將更進_步說明本發明的第二 =實施例，該第二較佳實施例與上述該第一較佳實施例 =相同’一樣能達到上述的諸多效果，其不同處在於該 4與轴承柱211是一體成型，該風扇馬達還包含一軸心定位片70。匕5旱由的广該心定位片7G是沿該轴線ζ方向設置於該軸承24 Γ:，同樣呈現配合該底面243下凹且中心位於該軸、，.纟5^瓜面’而能達成導引該“ 43的功能，並且還妒提=該底面243的耐磨效果，而在實際製造時，值得―匕的是該軸承24、該軸承柱211都可以在磨㈣鋼材料，於是也能提高耐磨的效果，而省略。疋位片70 TG件的安裝與材料成本。配合圖11所示，以下將更進-步說明本發明的第三較 … 列與上述該第二較佳實施例大目…、、不同處在於該殼體2G還包括—設切該框體U 末端朝向該軸線z延伸的防落件25，該防落件乃是一個夕邊形片體’可㈣鎖；點膠、高週波融合及卡釣等方式I 該框體22連結，都能達到防止該轉子4〇脫落的目的= 能避免該扣環50盥套擇^ 亚本與製程的功效。減少構件成實在由=說:將不難發現，本發明風扇馬達確轉％疋度、降低噪音及防止漏油和減小火塵附著等各方面都具有長^的進步，所以其產品價值= 更'出其它產品’市場競爭力也能大幅提升，充分滿足； 15 1283100 具製造與使用品質的優點滿足本發明的使用目的及功能惟以上所述者，僅為本發不能以此限定本發明實施之範利範圍及說明書内容所作之簡屬本發明專利涵蓋之範圍内。【圖式簡單說明】明三個較佳實施例而已，當圍’即大凡依本發明申請專單的等效變化與修飾，皆仍9·"Hai bearing 24 device on the fixed height bearing column 211, the assembly has a foolproof function, so the positioning is accurate without relying on or using any measuring tool to additionally perform the measurement action at any time, not only save the measurement At the same time, there will be no problem of poor quality similar to the traditional structure that will cause the positioning offset. 1〇·^ Invented the sleeve bearing 24 closed, the shaft 43 is short structural product 2 comparable to Ball Bearing, and the cost is low, the easy to buy and manufacture, so the product is very competitive.
