Specific implementation mode
Said program is described further below in conjunction with specific embodiment.It should be understood that these embodiments are for illustrating
The utility model and be not limited to limitation the scope of the utility model.The implementation condition used in embodiment can be according to specific producer
Condition do further adjustment, the implementation condition being not specified is usually the condition in routine experiment.
Referring to Fig. 1-4, it is the structural schematic diagram of the utility model embodiment, a kind of motor wind of large rotating inertia is provided
Fan comprising shaft 1, fixed disk 3 and fan 2, wherein fan 2 include fan set 2-1 and be arranged several on fan set 2-1
A fan leaf 2-2, fan, which covers 2-1, has mounting hole 2-3 fan 2 to be set in shaft 1, and fixed disk 3 is fixed on shaft 1
Axial end, fan set 2-1 is connected to the fixation disk 3, and when motor works, shaft 1 drives fixed disk 3 to rotate, 3 band of fixed disk
Dynamic fan 2 rotates, to make fan 2 work.
In this example, it is equipped with fixing axle 1-2 in the axial one end of shaft 1, the outer diameter of fixing axle 1-2 is less than shaft ontology 1-
1 and a shaft shoulder 1-3 is formed between shaft ontology 1-1, the fan set 2-1 of fan 2 is set on fixing axle 1-2, mounting hole 2-3
Matching with fixing axle 1-2, the one end fan set 2-1 is resisted against on shaft shoulder 1-3, and the other end is connected to fixed disk 3, in implementation,
