New Description: Oil-proof bearing fan oil leakage prevention structure (1), especially the oil leakage prevention structure that extends the service life of the fan. [New technical field] This creation is related to "a type of lubricant loss to avoid bearings. [Prior Art] As shown in Figure 1, there is a body 10, the body Π) central connection 疋 seat 11 a hollow shaft cylinder (1) is protruded from the clamp seat 11 (1). The shaft cylinder (1) is provided with a bearing 12, the _U1 jacket is provided with a coil 13; a fan wheel 14, the outer surface of the fan wheel 14 is &&; 141, a ring around the inner side of the fan wheel 14 - a magnetic ring (4) blood, the coil 13 is magnetically corresponding to the 'mail side side - a shaft 143, the shaft 143 penetrates the bearing 12 and is buckled by the buckle 15 and the oil ring 16 The position of the knot is only _ actual use, the bearing 12 will be released from the shaft 143 in which the high-speed rotation of the oil is released in the sintered hole to avoid dryness and loss, but only the oil ring 16 is provided on the shaft 143. It is not enough to prevent the lubricating oil from flowing out of the front end of the shaft (1). The material of the oil will flow outward with the centrifugal force of the shaft 143, and will flow out through the gap between the shaft 111 and the shaft 143. , causing the lubricating oil to be exhausted, and the change of the 143 position will be due to the lack of clear oil. Excessive friction, and the production of voices and life expectancy, does not meet the needs of users. 缘疋 In view of the shortcomings of the above-mentioned products, the creators of this case exhausted their minds and smashed the shirt year. Jue, concentrating on research and addition _ new improvement, M323525 finally successfully developed this piece of "oil bearing fan oil leakage structure (1)" case, it is a work of enhanced efficiency.

The above objects of the present invention, as well as its structural and functional features, will be described in accordance with the preferred embodiments of the drawings. [Embodiment] This creation provides a "oil-proof bearing fan oil leakage structure (1)", which is a preferred embodiment of the creation. Please refer to Figures 2, 3, 4, 4A, 4B, 5, and 6. The base 21 includes a base 21, a fan wheel 22 and a bearing 23. The base 21 can be disposed in a frame or a heat sink, and is provided with a shaft barrel 211. The shaft barrel 211 defines the bearing 23 The fan wheel 22 has a shaft 221 and the bearing 23 is disposed. The fan wheel 22 is pivoted on the base 21. The shaft barrel 211 has a first end 2111 and a second end 2112. The first end 2111 is connected to the shaft barrel 2, and a second oil reservoir 2113 is disposed in the second end 2112. The wearable piece 2114 and the at least one fastener 2115 are closed in the illustration, but the second end 2112 is closed, but it is not limited thereto, and may be open, and the second end may be closed by a bottom cover. 2112 (not shown). The inner surface of the fan wheel 22 is provided with a shaft 221 and a staggered structure 223. The staggered structure 223 is disposed around the shaft 221 and corresponding to the inner surface of the first end 2111. In a specific implementation, the staggered structure 223 includes There are at least one first annular recess 2231 and a second annular convex portion 2232. The first and second annular concave and convex portions 2231, 2232 correspond to the open end 2111, and the first annular concave portion 2231 is wound around the shaft. The second annular convex portion 2232 of the outer side of the rod 221 is disposed outside the first annular concave portion 2231 and adjacent to the inner surface of the first one h 2111. The M323525 "Hearing Bearing 23 is disposed in the shaft barrel 211, and includes a center hole 23 through which the center hole 231 extends, and the inner surface of the center hole 231 is divided into a chamfer 233, and at least the second oil reservoir 234 is disposed on the inner surface of the center hole 231. In addition, at least one groove 235 is provided on the outer surface of the bearing 23, and the groove 235 extends from the end of the bearing 23 to the other end. In the preferred embodiment, the second oil reservoir 234 is axially formed. The extension of L (as shown in Fig. 5) is not limited thereto, and it may also be spirally extended as shown in Fig. 6.
在則述轴桿221的一端貫穿該中心孔231後，被扣件2115扣 2對應於第-儲油槽2113中，同時該端面接觸該耐磨片2114，則 又於中。孔231内面之第二儲油槽234鄰對該軸桿22ι外表面。 、、如此軸桿221在轴承23中轉動時，第-儲油槽2113中的潤滑 ’由沿^桿221上升，使得大部分潤滑油保持於第二儲油槽234中， =刖=者乾摩擦’少部分持續沿著抽桿221上升的潤滑油受到 &狀的凹凸部挪、挪2峨止後，落人錐畑2犯並 可沿著抽承23表面的凹溝235流回第-儲油槽⑽，故經此重重 防護防止潤滑油外洩。After the end of the shaft 221 is inserted through the center hole 231, the fastener 2115 is fastened to the first oil reservoir 2113, and the end surface is in contact with the wear piece 2114. The second oil reservoir 234 on the inner surface of the hole 231 is adjacent to the outer surface of the shaft 22i. When the shaft 221 is rotated in the bearing 23, the lubrication in the first oil reservoir 2113 is raised by the rod 221 so that most of the lubricating oil is retained in the second oil reservoir 234, = 刖 = dry friction A small portion of the lubricating oil that continues to rise along the pumping rod 221 is subjected to the &-shaped concave-convex portion, and then the falling cone is smashed and can flow back along the groove 235 of the surface of the pumping member 23 to the first storage. The oil tank (10), so the heavy protection prevents the lubricating oil from leaking out.
