Description

technical field

[0001] The invention relates to a stator fixing seat, and in particular to a fan and its stator fixing seat. Background technique

[0002] see Figure 1A to Figure 1C , which respectively show the cross-sectional views of the existing fans 1, 1' and 1". Figure 1A As shown, the metal base 142 of the fan 1 is connected to the bottom of the metal bearing sleeve 140, which is fixed by riveting. Such as Figure 1B As shown, the metal base 142' of the fan 1' is connected with the metal bearing sleeve 140' through a bearing hole 1426' having the same height, which is fixed by coupling. Such as Figure 1C As shown, the bearing seat 18" of the fan 1" is made of metal bearing sleeve and metal base by aluminum die-casting. Therefore, the bearing seat 18" has the functions of supporting the bearing 16" and fixing the device at the same time.

[0003] In the background technology, the metal bearing sleeve and the metal base are usually designed in a high-precision i...
