Problems solved by technology
[0003] The rotor in the cooling fan is mainly composed of the shaft center and the fan wheel valley with multiple blades, and the stator is arranged outside the shaft cylinder of the fan frame and corresponding to the fan wheel valley. Generally, the fan shaft The barrel is integrally formed by the fan frame, and there is another cooling fan with a copper shaft. The copper shaft is riveted to the base of the fan frame by riveting, but this structure It is easy to cause the structure of the fan to be damaged due to the riveting process, and the riveting is not complete and easy to cause loosening and other disadvantages; and because the riveting work mainly uses pressure to force the copper shaft tube into the base of the fan frame, the copper It is also difficult to control the concentricity of the mass shaft and the base of the fan frame, and if it is easy to cause looseness after riveting, it is easy to generate noise
[0004] In addition, it is known that when the metal shaft cylinder and the metal fan frame are assembled with each other, because both materials are hard materials, when the fan is running, the vibration will cause the metal shaft cylinder and the metal fan frame to resonate and generate noise.

The invention discloses a fan shaft barrel combining structure which comprises a shaft barrel base, a bottom plate and a connector; the shaft barrel base is provided with an accommodating space, a receiving part and a shaft hole; the shaft hole is formed in the top end of the shaft barrel base, and communicates with the accommodating space; the receiving part is arranged at the outer edge of the other end, opposite to the shaft hole, of the shaft barrel base; the bottom plate is provided with a hole; the receiving part is arranged in the hole; and the connector is connected to the shaft barrel base and the bottom plate in an injection molding manner. By virtue of the fan shaft barrel combining structure, concentricity of the fan shaft barrel and each element can be greatly increased, and the elements are combined stably.
Description
【Technical field】 [0001] A fan shaft-tube combination structure, especially a fan shaft-tube combination structure that can improve the precision of the combination of the fan shaft tube and the fan frame body and improve the concentricity. 【Background technique】 [0002] Existing cooling fans are mainly used for forced-guided airflow for heat dissipation where heat dissipation is required, and cooling fans are mainly used to guide the airflow by generating inductive excitation between the rotor and the stator to cause the rotor to rotate. [0003] The rotor in the cooling fan is mainly composed of the shaft center and the fan wheel valley with multiple blades, and the stator is arranged outside the shaft cylinder of the fan frame and corresponding to the fan wheel valley. Generally, the fan shaft The barrel is integrally formed by the fan frame, and there is another cooling fan with a copper shaft. The copper shaft is riveted to the base of the fan frame by riveting, but th...
