New Description: [New Technology Field] [0001] This creation provides an improvement in the structure of oil-impregnated bearing fans, especially an oil-bearing bearing fan that can reduce wear and reduce running noise and vibration, and improve service life. [Previous technology] _] Press, the use of electronic information products (such as computers, etc.) is becoming more and more popular and widely used. As demand drives the rapid development of electronic information industry technology, it promotes the improvement of electronic information to the implementation of computing and access capacity. The increasing trend of development has led to the occurrence of high temperatures associated with the use of components of the aforementioned electronic information product towels at high speeds. Taking a computer mainframe as an example, the internal central processing unit (cpu) generates a large amount of heat. In addition, when the central processing unit is gradually increased in heat, the performance is lowered, and when the heat is accumulated above its allowable limit, This will cause the computer to crash, in severe cases, it is more likely to cause damage; and 'to solve the problem of electromagnetic radiation, usually the chassis is used to close the computer, so that the central processing unit and other heating components (or It is called "it") that the heat is quickly exported and becomes an important issue. The method for solving the heat dissipation by the central processing unit is to provide a heat sink and a cooling fan above the heat sink, and the __ side of the heat sink is configured with a plurality of recording sheets to the other side of the heat sink (not The surface having (4)) is in direct contact with the central processing unit "to enable thermal energy to be conducted to the end of the tablet, and the heat is quickly dissipated by the heat dissipation of the bulb and the fan." As shown in Fig. 1, The three-dimensional form number of the oil-impregnated heat-dissipating fan of the prior art is Α 0101. The third embodiment has a fan base 11 having a shaft ^] 111 ' A bearing 12 is disposed in the shaft ill, and a fan rim 3 is disposed on the fan base 11. The outer ring of the fan wheel 13 is provided with a plurality of blades 131, and an axial center 132 is extended on the inner side, and the shaft 132 is worn. Provided in the bearing 12 and fastened and positioned, the bearing 丨 2 and the shaft 132 are filled with an oil film 121 ′ and the position of the fan base 11 and the bearing 12 and the fan wheel 13 are mutually adjusted to optimize operation. Position, when its cooling fan 1 is in operation The axis 132 of the shaft 132 can be stably rotated on the bearing 12 by the oil film 121, so that the shaft 132 is supported by the supporting force of the oil film 121 with respect to the operating position of the bearing 12, but the branch of the cooling fan 1 whose oil film 121 is generated The force is still less than the eccentric force generated during its operation; therefore, there is still a frictional collision between the axial center 132 and the bearing 12, or when the cooling fan 1 is subjected to an external force, the external force will also cause the collision force. The position of the shaft 132 is offset, and even the shaft 132 collides with the bearing 12 to generate vibration, so that the cooling fan 1 generates noise and vibration noise due to its positional displacement or collision, and also The wear of the shaft 132 and the bearing 12 is increased, which affects the service life of the cooling fan 1: or the supporting force of the oil film 121 thereof can return the axis 132 to the optimal operating position, but the oil film 121 is squeezed. After pressing, it takes a long time to recover, and the time for returning to the optimal operating position relative to the axis 132 is relatively increased, and the time for generating noise and wear is relatively prolonged; therefore, the prior art has the following disadvantages: It is easy to generate vibration and noise; 2. Increased wear and tear; 3. Low noise generation; 4. Impact on service life. Form No. A0101 Page 4 of 17 is how to solve the above problems and problems That is, the creators of this case and the relevant manufacturers engaged in this industry are eager to study the direction of improvement. [New content] [0003] Therefore, in order to effectively solve the above problems, the main purpose of this creation is to provide a kind of Reduce wear and reduce running noise and vibration, and improve the structure of the oil-containing bearing fan with the use of the life. Another purpose of this creation is to provide an oil-bearing bearing fan structure that can quickly restore the stability of the fan. In order to achieve the above purpose, the present invention provides an improved structure of an oil-impregnated bearing fan, comprising a fan base, an oil-impregnated suction bearing and a wheel, the fan base having a shaft cylinder on one side thereof, the shaft cylinder having a bearing hole And comprising at least one magnetic component, the oil bearing is disposed in the bearing hole, and the oil bearing has an axial hole, the fan wheel has a plurality of blades and an axis, wherein the axis is pivoted In the axial hole; thereby, the magnetic element can generate a magnetic attraction force to the shaft through the magnetic element, so that the shaft can quickly return to the optimal operating position, thereby reducing wear and reducing running noise and vibration, and improving the service life. The effect of this creation; therefore, the creation has the following advantages: 1. Reduce the generation of vibration and noise; 2. Reduce the occurrence of wear; 3. Reduce the noise generation time; 4. Lift the service life.

The shaft center 42 is pivotally disposed in the shaft hole 31, and the shaft 42 has a relationship between the shaft core 42 and the shaft hole 31. a hydraulic layer of the oil film, wherein the shaft 42 is disposed in the shaft hole 31 when the fan is required The positional test between the seat 2 and the oil-impregnated bearing 3 and the fan wheel 4 is adjusted to an optimal operating position, and in the adjusted position, the magnetic element 212 included in the barrel 21 generates a magnetic attraction force to the axis 42 thereof, and And the hydraulic layer generates a floor force on the axial center 42 thereof, so that the magnetic core absorbing force and the supporting force of the hydraulic layer can effectively position the axial center 42 at the optimal operating position, and the fan When the wheel 4 is in operation, the shaft 42 can still be maintained at the optimal operating position through its magnetic attraction force, and the stability of the operation between the shaft 42 and the oil-impregnated bearing 3 is improved to reduce the wear and tear and reduce the tumbling noise. If the structure of the oil-impregnated bearing fan is improved by an external force, the impact force of the external force will shift the position of the axis 42 or even cause the axis 42 to collide.
