When the shaft core A rotates, the oil guiding groove A 1 of the shaft core A cannot effectively suck the lubricating oil in the oil tank C 2 upward, thereby lubricating the oil tank C 2 . The oil cannot enter the gap between the core A and the bearing B to be lubricated. 3. The top of the sleeve C used in the above is open. If the fan is placed in the process of packaging, transportation, assembly, use, etc., it is possible to place the fan laterally or upside down, so that the oil groove C 2 at the bottom of the sleeve C The lubricating oil flows out along the gap between the core A and the bearing B, and the centrifugal force generated by the high-speed rotation when the core A rotates, so that the lubricating oil flowing on the surface of the core A is easy to pull out of the sleeve In addition to C, the lubricating oil in the oil groove C 2 is reduced and the lubricating effect is lowered, and the lubrication effect of the axial core A and the bearing B is poor, and external foreign matter, dust or impurities are also easily entered, so that the axial core A and the bearing are Grease is generated at B, which causes the shaft core A to be unsmooth and frictional when rotated, so that the overall service life is shortened. The above-mentioned problems with the structural devices of the fan shaft core and the bearing are in need of improvement, which is the direction that the creators and those engaged in the industry desire to improve.

第6頁 ，M284772 四、創作說明（3) 由不斷試作及修改，始設計出此種具極佳密閉效果而使潤 滑油不易外漏之改良結構的新型專利者。 本創作之主要目的則在於轴管之容置空間上、下二側 分別設有具穿孔之上蓋及下蓋，且容置空間内為收容有具 軸孔之軸承，並使軸管之内壁面或軸承之外壁面處設有溝 槽，而轴承與上蓋間形成有甩油空間，另軸承與下蓋間則 形成有儲油空間，當軸芯依序穿設於上蓋之穿孔、軸承之 軸孔及下蓋之穿孔内呈一定位時，其軸芯表面剖設之導引 槽為位於儲油空間與軸承之間，當軸芯於高速旋轉時，可 藉由導引槽將潤滑油夾帶至軸芯及軸承處，再藉離心力 作用將潤滑油呈輻射方向甩開至甩油空間内，最後潤滑油 透過甩油空間内所設之導流定位肋的導引，將潤滑油沿著 溝槽回流至儲油空間内形成一循環，俾使潤滑油同步潤滑 軸承及轴芯的同時不會往外洩漏。 本創作之次要目的乃在於軸承底部與下蓋間之儲油空 間内可進一步設置有彈性多孔含油體，當潤滑油循環回流 至儲油空間時，其彈性多孔含油體可將潤滑油所夾帶之雜 質、細屑予以過濾，以保持潤滑劑之潔淨，進而達到潤滑 油最佳之潤滑效果。 • 本創作之再一目的乃在於軸芯與上蓋之穿孔間的間隙 處與軸芯與下蓋之穿孔間的間隙處可進一步填入固態油， 如此，當基座不論呈橫向傾倒放置或是上下顛倒放置時， 不致造成容置空間内的潤滑油外流溢出，防止潤滑油盡數 流出而造成軸芯旋轉不順暢、磨擦損壞，且可同時防止外Page 6, M284772 IV. Creation Instructions (3) From the continuous trial and modification, we have designed a new patented patented system with an excellent sealing effect that makes the lubricating oil difficult to leak. The main purpose of the creation is that the upper and lower sides of the shaft tube are respectively provided with a perforated upper cover and a lower cover, and the bearing space accommodates the bearing with the shaft hole and the inner wall surface of the shaft tube Or a groove is formed on the outer wall surface of the bearing, and an oil space is formed between the bearing and the upper cover, and an oil storage space is formed between the bearing and the lower cover. When the shaft core is sequentially passed through the perforation of the upper cover and the shaft of the bearing When the hole and the bottom cover are positioned in the perforation, the guiding groove of the surface of the shaft core is located between the oil storage space and the bearing. When the shaft core rotates at a high speed, the lubricating oil can be entrained by the guiding groove. To the shaft core and the bearing, the centrifugal force is used to open the lubricating oil into the oil space, and finally the lubricating oil is guided through the guiding rib provided in the oil space to guide the lubricating oil along the groove. The tank returns to the oil storage space to form a cycle, so that the lubricating oil synchronously lubricates the bearing and the shaft core without leaking out. The secondary purpose of this creation is that an elastic porous oil body can be further disposed in the oil storage space between the bottom of the bearing and the lower cover. When the lubricating oil is circulated back to the oil storage space, the elastic porous oil body can entrain the lubricating oil. Impurities and fines are filtered to keep the lubricant clean and to achieve the best lubrication of the lubricant. • A further object of the present invention is that the gap between the core and the perforation of the upper cover and the perforation between the core and the lower cover can be further filled with solid oil, so that when the base is tilted laterally or When placed upside down, it will not cause the outflow of lubricating oil in the accommodating space to overflow, prevent the lubricating oil from flowing out, causing the shaft core to rotate unsmoothly, and the friction is damaged, and at the same time, it can be prevented at the same time.

The cycle effect of the creation description (7). 3. The oil storage space of the present invention can be further provided with an elastic porous oil body 1 8 . When the shaft core 2 rotates, the elastic porous oil body can be directly driven to release the lubricating oil to lubricate the shaft core 2 . At the same time, it provides a larger oil storage capacity in the oil storage space to extend the effect of oil retention and lubrication, so as to achieve long-term lubrication of the shaft core 2 and the bearing 14 and extend the life of the fan. 4. The oil storage space of the creation may be further provided with an elastic porous oil body 1 8 to store a large amount of lubricating oil and absorb it to prevent the lubricating oil from being applied to the upper cover 1 when the base Φ seat 1 is placed laterally or upside down. The perforation of 2 is 1 2, and the exhaust of the shaft core 2 is lost. 5. The gap between the core 2 of the present creation and the perforation 1 2 1 of the upper cover 1 2 and the gap between the shaft core 2 and the perforation 1 3 1 of the lower cover 13 may be further filled with solid oil, so that when When the pedestal 1 is placed in a horizontal direction or placed upside down, it does not cause the outflow of the lubricating oil in the accommodating space 110 to prevent the lubricating oil from flowing out, causing the shaft 2 to rotate unsmoothly and the friction is damaged, thereby affecting the shaft. The speed of the core 2 increases the noise, and at the same time prevents external dust, foreign matter, fines, etc. from entering the accommodation space 1 1 0, and avoids the formation of grease stains to keep the lubricant® clean. The above detailed description is intended to illustrate a preferred embodiment of the present invention, and is not intended to limit the scope of the present invention, and other equivalents and modifications may be made without departing from the spirit of the invention. Changes shall be included in the scope of patents covered by this creation.
