Description of the new type: [Technical field to which the new type belongs] This case relates to the creative improvement of a variety of riding shafts, especially those that can be applied to a fan shaft with a reduced friction area inserted into a sliding bearing. [Previous technology] The fan blade button of the general cooling fan is mounted on the frame for positioning, which is achieved by using a sliding bearing, a shaft sleeve and a washer, and a C-shaped buckle. For example, the riding bearing 2 ′ is placed behind the fan blade Γ for the fan blade! The shaft 11 of the '' is inserted into the casing 3 'and can be operated to reduce the frictional force of the shaft ^ of the fan blade i' when rotating and sliding up and down. Ran-Smooth_The friction between running and turning under Lai Changka's operation will cause the inner diameter surface to be irregular or elliptical, which will affect the smoothness of the operation, and will also generate mechanical noise and reduce the use of brother's life Etc. Missing. Therefore, the industry has further developed conventional sliding bearings into oil-containing sliding bearings' to reduce the amount of gifted bearing wires, reduce mechanical noise, and extend the service life of fan blades caused by long-term operation. In terms of the process of oil-containing sliding bearings, it uses sintered alloys to form the oil-containing bearings by using the inner diameter surface of the bearings. In this way, the process of oil-containing sliding bearings not only requires more mechanical forming, but also requires high processing technology f The equipment installation cost is also high. For the cooling fans sold at low unit prices, it has a factor of unfavorable capacity increase, and the cost of production 2 will affect the lack of sales profits and product competitiveness of the cooling fans, which is necessary. To improve. M268877 [New content] This creation is based on the use of heat-dissipating wind-type sliding bearings, which is based on the lack of the above-mentioned oil-containing sliding bearings to improve them, and then provides _ a kind of slippery bearing that can be used to reduce the friction: the fan shaft of the friction area, For industrial use. The technical section of this county has miscellaneous __ 峰 陈 表面 烧 surname, Meng forming process technology is highly demanding and the equipment installation cost is high, etc., it is further cut on the ^ 2 blade shaft at the contact part of the sliding bearing Machining a number of recessed shapes 2 / To facilitate contact with the contact parts, slip the wire and shame to reduce the role of storing lubricating oil, and push it to know that ± 7 --area and grooves and further _ the inner diameter surface of the moving bearing The lubricating effect can achieve the following effects: reduction of sound and turn of life in Canada. Its effect is the same as that of private oil-containing sliding bearings, and in this way, the force of a certain axis can reduce the abundance of contact parts: area and Oil-storage type, this recessed groove can be cut and formed during the processing of the fan shaft, the processing process is simple, and the technical demand is low. For the cooling fan of Tai, Bei, '1 In other words, this creation has the same effect, and can reduce the manufacturing process and increase the production capacity and product competitiveness. This is the main purpose of this creation. [Embodiment] Please refer to the second to fourth figures. The wound blade shaft of the present invention, the complex-Ha "Zhasuo M, a fan with reduced friction area", 疋 is placed at the center position behind the fan blade 1, and The other end is inserted, and the force is determined by the inside of the bearing 2 using a clip to block it. ^ In the frame 31 γ 1. Make the fan a miscellaneous setting position. This axis # π j on the rod and the sliding bearing 2 4 grooves in diameter L are cut and processed. M268877 Therefore, as shown in the third figure, when the shaft u of the fan blade i is inserted into the sliding bearing 2 _ face 21 'the contact portion L of its shaft n is cut by machining several recessed shapes ^ ⑴' relative sleeve The human sliding bearing 2 can reduce the friction area with the inner diameter surface 21, and the city groove 111 has the function of storing the lubricating oil 4. Therefore, when the fan blade i or the sliding bearing 2 rotates, the wear of the shaft u and the inner diameter surface 21 of the sliding bearing 2 decreases relatively, and the lubricating oil 4 stored in the groove m can produce a lubricating effect. The frictional heat generation temperature can also be effectively reduced while operating the machine. The noise can be reduced and the service life is long. Its effect is the same as the conventional oil-containing sliding bearing. Eight ~ that is the peach cutting fan blade! The shaft u can reduce the contact area = friction area and oil-storage lubrication method. This _ crane groove can be used in the fan blade ^ U rod + bucket-and-times _ made by Jiawei forming, plus reading Simple and low-demand for the low-priced products __ language, this creation has a sample of the post containing I I release and reduce the manufacturing cost, as well as improve the production capacity and product competitiveness. Of course, this The contact portion L of the inner diameter surface 21 of the movable bearing 2 on the upper shaft U is processed: the recessed shape of a dry groove is not limited to the rectangular shape shown in the third figure = the red groove m of the surface type, which Can also be made as the v-shaped groove surface shape of the supplement 111 shown in the fourth figure or can be made into a continuous groove groove surface shape as shown in the fifth figure, or can be made into the sixth The groove U1 of the semi-circular groove surface shape shown in the figure, or the groove U1 of other dentate, spaced or continuously extending groove surface shapes. However, the second and the second types disclosed above: the type diagrams and descriptions are only examples of this creation, not the implementation of the R row; it is the characteristics of those who are familiar with this skill and based on this creation Fan Hi, M268877's = She's modification should be included in the scope of the patent. To the author, the bribery provided by this studio with reduced friction area can really achieve the value and purpose of the page, which is extremely industrial creators. Cho 4 is suitable for consistent blades [Schematic description] The first figure shows the assembly relationship between the fan blade and the sliding fan of the cooling fan. The corresponding relationship is shown in the second figure. Create a picture of the money of the cooling fan and the sliding surface. The picture is not related to the combination of the rod and the sliding bearing of the creative surface. The fourth picture shows another creative-better DL Schematic ^ ', a schematic diagram of the fan shaft of the example. Section ^ is a schematic diagram of the fan blades of the present invention, the preferred embodiment. , Huisuo is not a creative illustration of the fan blade of the preferred embodiment.
