Description

M326974 VIII. New description: [New technical field] The creation system provides a self-adjusting concentricity bearing, especially a pre-rotation device (for example, cooling fan, disk drive, CD player, The central axis of the motor or other shaft device that needs to be pivotally rotated by the bearing automatically adjusts the concentricity of the alignment bearing, and can be rotated and slipped in an all-round automatic fine adjustment to achieve the purpose of good concentricity, thereby effectively extending Preset the life of the hinge unit. 【 【Prior Art】 If the traditional rotating mechanism has a long service life, it must effectively avoid the collision between the rotating shaft and the bearing, the situation of the county, and the appropriate clearance between the rotating shaft and the bearing of the county. Lubricating oil is lubricated, and in the assembly of a single bearing and rotating mechanism, it is usually a tight fit interference method to avoid the synchronous sliding rotation of the bearing in the rotating mechanism, but such interference will cause quite a lot of problems, such as: The cooling fan applied to the computer, the combination of the bearing and the rotating mechanism, the interference assembly of the thin bearing, the matching with the fan frame, and the pressing of the steel sheet into the outer diameter of the tube in the fan frame, also using a tight fit Interference method, however, the fan frame is squeezed by the inner and outer bearings and the silicon steel sheet group, and it is easy to produce problems such as bearing misalignment and poor concentricity after assembly, so that the assembly rate of the cooling fan is biased. Low, even when the concentricity is good after assembly, it will also cause problems such as stress release in the fan frame, and it is very easy to cause bearing misalignment and abnormal sound in the future. Causes dissatisfaction and complaints from customers. However, when two bearings are to be assembled into the same rotating mechanism at the same time, the misalignment of the 5 M326974 bearing will be more serious and complicated, for example, a single ceramic bearing and a single-oil bearing, assembled at the same time as the above fan. In the tube inside the frame, the misalignment and the concentricity of the post-cracking axis are more serious, and the collision and friction between the rotating shaft and the ceramic shaft 2 (or the oil bearing) occur, and the difference is produced. Sound or noise' is even worse, and the temperature rise caused by frictional contact with each other advances: Reduces the service life of surrounding electronic components. Since the hardness of the bearing is almost double the hardness of the rotating shaft, and when the rotating shaft and the _axis are in collision and friction, the surface of the rotating shaft will be: The bearing of the bearing is scratched and damaged. At the same time, it will even blow out the deep groove marks, and the metal lions coming down will be easily smashed by the air (four) degree and moisture, and will be blocked in the gap between the rotating shaft and the bearing, resulting in a rotating mechanism. The function is invalid. In addition, the hardness of the rotating shaft is more than double the hardness of the bearing. For example, the oil bearing and the rotating shaft are inspected and matched, and the same, the reading is not good, and the collision occurs, k friction, etc. 'Because the oil bearing is a porous structure There will be a sound-absorbing effect, although it will not cause the rotating mechanism to operate, there will be obvious abnormal sounds, but due to the collision and friction between the bearing and the rotating shaft, the oil-impregnated bearing will be reamed under long-term use. The situation occurs, thus reducing the service life of the rotating mechanism. However, the collision and friction between the bearing and the rotating shaft due to insufficient turbidity and slipping will also produce a mutual thermal effect. The oil in the oily oil will rise due to the temperature rise after the temperature of the oil-bearing bearing rises to a certain temperature. The density is reduced, which in turn causes the oil that is intended to penetrate into the pores of the oil-bearing bearing to gradually evaporate toward the outside of the oil-impregnated bearing, so that after operation - a period of time, it is still possible to make the situation more obvious due to lack of oil. It can also cause damage to oil-impregnated bearings or shafts, which in turn reduces the service life of oil-impregnated bearings or shafts. Furthermore, when the aspect ratio of the bearing is increased, due to the difficulty in the assembly and the alignment, the bearing misalignment caused by the interference and assembly of the bearing and the rotating mechanism, the 2nd is in the same situation as the rotating shaft. It will also be more stringent. The result is that the assembly yield of the entire rotating mechanism is low, and the production and manufacturing costs are increased, and it is not in line with economic considerations.
