Detailed Description
Specific examples of the present invention will be described in further detail below. It should be understood that the description herein of embodiments of the invention is not intended to limit the scope of the invention.
Please refer to fig. 1 to 3, which are schematic diagrams illustrating a separation structure of a fan convenient for concentric positioning according to the present invention. The fan facilitating concentric positioning includes a wind wheel assembly 10, and a stator assembly 20 embedded in the wind wheel assembly 10. It will be appreciated by those skilled in the art that the fan facilitating concentric positioning may further include other functional components, such as a rotor assembly, a driving assembly, a mounting assembly, etc., which are well known to those skilled in the art, and therefore will not be described in detail herein.
The wind wheel assembly 10 includes a hub 11, a shaft core 12 connected to the hub 11 and concentrically disposed with the hub 11, and an impeller 13 disposed outside the hub 11. An annular step 113 is arranged on the inner wall of one side of the hub 11 far away from the stator assembly 20. It is contemplated that the annular step 113 may enhance the structural strength of the interior of the hub 11. An annular notch 111 which is concentric with the shaft core 12 is formed in the inner wall of one end, close to the annular stator, of the hub 11 by turning the shaft core 12 as a central shaft. A positioning shoulder 112 is formed on the inner wall of the end of the hub 11 facing away from the annular stator, and the positioning shoulder 112 is arranged between the annular step 113 and the annular recess 111. The wind wheel component 10 is formed by integral die-casting, namely, the hub 11, the shaft core 12 and the impeller 13 are of an integral structure, and the wind wheel component 10 formed by integral die-casting is compact in structure and reliable in connection. In addition, the impeller 13 includes any one of an axial flow type impeller and a centrifugal type impeller, and in the present embodiment, the impeller 13 is an axial flow type impeller.
The stator assembly 20 includes a ring-shaped stator 21, and an aluminum casting 22 passing through the ring-shaped stator 21 and having both ends protruding from the ring-shaped stator 21. The annular stator 21 is provided with an abdicating notch 213 for the cast aluminium 22 to pass through. The circumferential edge of the aluminum casting 22 is located inside the circumferential edge of the end of the annular stator 21 and a positioning step 211 protruding from the circumferential outside of the aluminum casting 22 is formed on the outer wall of the annular stator 21. It is conceivable that the radial length of the positioning shoulder 112 is smaller than the radial length of the positioning step 211, and the axial length of the positioning shoulder 112 is larger than the axial length of the end of the cast aluminum piece 22 protruding from the impeller 13, so that the positioning shoulder 112 abuts against the positioning step 211 by setting the dimensional relationship between the positioning shoulder 112 and the stator assembly 20.
When the stator assembly 20 is inserted into the hub 11, the annular stator 21 is inserted into the annular gap 111 and the positioning shoulder 112 abuts against the positioning step 211. By means of the positioning structure between the positioning shoulder 112 and the positioning step 211, a limit point can be provided for the insertion mounting of the annular stator 21, and whether the annular stator 21 is completely inserted into the annular gap 111 can be determined.
