[Prior Art], the bearing is used to support the weight of the bearing, and the material of the ball is good, (10) the bearing supports the „ journal. _ The friction between the bearing and the bearing will cause a lot of power loss and damage to the bearing 2 [, discuss When bearing, 'the method of reducing friction must be considered, and the heart of the shaft produces s Φ bearing to bear the 'because it needs to have sufficient strength and sufficient lubrication. ρΓΙ f, a wide variety of 'f see the station is divided into ball age , liquid bearing and Tao Lucheng, 4 beads bearing 'it is _12 steel balls to support the weight of the motor, so b rotation will produce metal surface friction, the steel ball will produce grinding mnout when rotating This kind of special motor speed is getting higher and higher, which causes the biggest difference between the white steel sputum bearing and the rolling bearing in the ball bearing use. Not in the sleeve 3, the inner edge of the conventional bearing 11 is attached with a layer of oil film to make the rotation; 1 'for the other end of the lining 4 work' and the ideal liquid miscellaneous is the oil film support. In the field, the lions will not be able to absorb vibrations and problems. The liquid pumping is more important than the ball pumping, but it is ideal for the "no wear" state of the liquid bearing. It is still 5〇5208/the mechanism for the storage and lubrication of the slippery agent. The technical means of the improvement of the air-bearing structure of the first hollow is to improve the bearing with the oil-absorbing oil of the bearing, to provide lubrication of the rotating shaft, the low; similar to the creation of the two ends of the bearing The lubrication effect on the contact surface with the rotating shaft is obviously reduced n^n^nnZ 〇^35〇495f^^ #充, though, to accommodate more faces, and often compensate for unevenness, when the door is in the lion The mechanism of balanced oil distribution will probably result in the effect of grinding and the __, which will not only reduce the operation, but also shorten the long-term bearing, which will cause the bearing to wear too much and lose its function and life. In the evening, the cost of manufacturing is also rising. Therefore, how to make sure that _ 1305245 is the most important issue for setting up a lion. The sum of the energy and the potential energy is - the value of the '_Binnuuli equation: the pressure, the pressure difference caused by the movement, will save the 帛~^ to push the line flow rate difference agent when the bearing is overturned to the second gas room. Under the low speed _ can be lubricated by atmospheric pressure [Embodiment] Help Rotary County - view fan bearing structure improvement, is used to include ''friction, make the rotating shaft 1 work more efficiently, the present invention package-fan The other 2 is equipped with a lion in the rotation axis of the bearing 2. The rotating shaft is 1 - terminated with a stomach ====2 r ' where Na Cheng 2 and · 1 contact in the instructor 2Γ = product of the first - gas a chamber 21 and a second air chamber 22, wherein the first portion is formed, and the first self-end surface extends inwardly but does not communicate to the other end surface of the first section trench 210. The second chamber & The first splitting groove 210 is formed, the 21st, and at least the first air chamber slip agent 5, which is closed by the sleeve 3, has a larger cross-sectional area, and the oil film tension is greater than the second gas. The static pressure in the chamber 22 and the lake ώ 1 are installed in the bearing 2 to statically press the first air chamber 21 and the second air chamber 22 and the sleeve 3 'membrane tension mechanical positioning, and the field _ 1 material two air chamber 22 and bearing 2 into (four) stress-inclined flow, the shape is one ~ ί according to the invention 'mainly fine from the Nuoli equation: the sum of pressure, kinetic energy and potential energy and this quadratic flow rate In proportion, when the flow rate through the gas chamber is smaller, the pressure difference principle of 6 1305245 is generated, so that the first and second cross-sectional areas of different sizes are formed between the bearing 2 and the rotating shaft of the present invention. In the gas chambers 21 and 22, when the rotating shaft is forced to rotate, since the cross-sectional area of the first air chamber 21 is larger than the second air chamber 22, the flow rate flowing through the first air chamber 21 is slow, resulting in the first gas. The pressure of the chamber 21 is greater than the second air chamber 22, and the pressure difference between the first air chamber 21 and the second air chamber 22 forces the lubrication 5 to push the tangential point of the silk film from the tangential plane to the second air chamber 22 to rotate the shaft 1 The solid body is supported by the rotator with a great tension, and the rotating shaft 1 is extended to the bottom of the slab 3 and is provided at the bottom of the sleeve 3 with a wear-resistant material. When the rotary shaft i rotates, only the end of the rotary shaft i is in direct contact with the sharpening sheet 31 in a point contact type, thereby achieving the purpose of low friction loss. In addition, Fen this invention considers the rotating shaft! In the low-speed running state, and in the initial positioning, the oil film has not yet been fully upgraded, and the oil film has not yet been completely produced. This is the case that she is riding the wire bearing 2 Wei w chain. Therefore, the present invention 'SA ~, miscellaneous tube 3 Forming a third air chamber 24, or providing a plurality of sets of second splitting grooves 2 at the outer periphery of the bearing 2 to: 3⁄4-shaped a bearing 2 difference, and the plurality of (four) n reinforcing items to 24 and - The pressure μ of the gas chamber 21 is much higher, and the second groove 240 is equally divided into the outer circumference of the bearing 2, and the flute-齑 and the first air chamber 21 are multiplied by a peripheral angle of the concave (four) s, and the second oxygen chamber 24 assists. Stable fixed position effect. The oil film produced by the initial rotation of the shaft 1 can be effectively used. The present invention is not limited to the second section of the bearing 2, which is different from the pressure of the first to the 21st, and may be provided in the blade 4 or the sleeve. 'As long as the outside air is connected to the first air chamber 21, the third air chamber 24 and the second/second two are reinforced; please refer to Figs. 6 and 7, and another embodiment will be the inner circumference, _ the sleeve The pressure difference between the third section 32 is set in the sleeve, so that the amount of cooked Er Er 32 up to the sample to push the lubricant at atmospheric pressure, the invention of the invention;: bearing = good lubrication effect. The advantages of the simplified force _; 1 = Γ are as follows: The oil film of the lubricant 5 is balanced by the lubricant 5 distribution. Contact without wear and tear. The first gas is 22, so that the rotating shaft 1 is hardly connected to the bearing 2, and the gas seal is formed between the rotating shaft 1 and the second air chamber 22 and between the bearing 2 and the sleeve 3, so that the lining agent 5 is subjected to atmospheric pressure. However, it is impossible to flow outward, forming a natural seal to avoid the loss of the agent 5, and to generate a larger oil film pressure to protect the bearing 2 during operation. , 3. Construction is simpler than previous creation, cost-saving, and easy to produce quickly. The foregoing is a preferred embodiment, and the present invention has been described as a preferred embodiment of the present invention, and is not intended to limit the invention, and it is intended to be within the spirit and scope of the invention. A few modifications and refinements are intended to be included in the present invention.
