Bearing coupling structure

The present invention relates to a bearing joint structure, and more particularly to a bearing joint structure which can improve the service life of a bearing and a shaft barrel.

According to the advancement of the technological era, the operational efficiency of electronic components is becoming higher and higher, so that the requirements for the heat dissipation performance of the heat dissipation unit to the electronic components are also increased.
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 gradually increases in heat, the performance is reduced, and when the heat accumulation is higher than its allowable limit, Will force the computer to crash, in severe cases is more likely to cause damage; and, in order to solve the problem of electromagnetic radiation, usually the chassis is used to close the computer host, so that the central processing unit and other heating components (or The rapid export of the thermal energy of the component is an important issue.
Or large electronic devices such as general workstations or servers may generate high temperatures during operation. If the operating temperature exceeds a certain operating temperature, the high temperature may affect the performance of workstations, servers, etc., or even affect workstations and servers. The electronic components in the mainframe are burned and cause malfunctions, especially the data files or files stored in the workstation or the server are more important, so the short-term crash or damage will also cause subsequent losses, so the workstation When the server is erected, how to dissipate heat to maintain the temperature within the operating temperature range is a very important design step.
Therefore, the high-efficiency heat dissipating unit is one of the most important research and development priorities in the industry today, and the high-temperature electronic component is provided with a heat dissipating unit and dissipates heat to the electronic component through the heat dissipating unit, and the heat dissipating unit is usually The heat sink or heat sink fins are equipped with a cooling fan for heat dissipation.
Referring to FIG. 1 , which is a perspective view of a bearing assembly structure of the prior art, the heat dissipation fan 1 has a base 11 and a rotor set 12 and a certain subset 13 . The base 11 has a shaft cylinder 111 and A bearing 112 is disposed inside the shaft cylinder 111. The bearing 112 is matched with the tolerance of the inner diameter of the shaft cylinder 111 so that the bearing 112 can be disposed in the shaft cylinder 111 and the bearing 112 can be prevented from coming out, and the shaft cylinder 111 is removed. The stator assembly 13 is externally sleeved, and the rotor assembly 12 has a hub 121, a plurality of blade bodies 122 and a shaft center 123. The shaft center 123 is inserted into the bearing 112 when the cooling fan 1 is running. The shaft 123 of the rotor set 12 rotates relative to the bearing 112, but the bearing 112 does not have any positioning arrangement in the barrel 111, so that the shaft 123 rotates relative to the bearing 112, the bearing 112 is rotated or slid in the shaft 111 by the influence of the shaft 123, and after the long-term operation of the cooling fan 1, the bearing 112 and the shaft 111 may wear and generate debris or powder. This causes the bearing 112 to fail and the rotor set 12 to operate unsmoothly.
As mentioned above, the conventional disadvantages have the following disadvantages:
1. The bearing will rotate or slide due to the influence of the shaft;
2. Reduce the service life of bearings and shafts.
Therefore, how to solve the above problems and problems in the past, that is, the creators of the case and the relevant manufacturers engaged in this industry are eager to study the direction of improvement.

Therefore, in order to effectively solve the above problems, the main purpose of the present invention is to provide a bearing coupling structure which can increase the service life of the bearing and the barrel.
The secondary purpose of this creation is to provide a bearing coupling structure that can rotate or slide the bearing without being affected by the axis.
In order to achieve the above object, the present invention provides a bearing coupling structure including a base and at least one bearing, the base having a shaft cylinder, the shaft cylinder is formed by a convex portion at the center of the base, and the shaft cylinder Forming an accommodating space therein, the bearing is received in the accommodating space, the bearing has a shaft hole, and the inner wall of the shaft cylinder and the outer wall of the bearing can be provided with at least one groove simultaneously or in any one of them, and The trench is in communication with the accommodating space.
Through the design of the structure of the present invention, a molten filler may be disposed on the groove content and welded to the filler by laser welding to bond the bearing and the shaft cylinder to each other, thereby preventing the bearing. Rotate or slide without being affected by the shaft to improve the service life of the bearing and the barrel.
