The second circular ring shell 322 that the outer edge of two Circular Plates 321 extends to the axial another extreme direction of alloy mandrel 2；First Circular Plate 311
The interval setting in the axial direction between the second Circular Plate 321.As a result, under Centrifugal Load, the first alloy wheel hub 31
With the second alloy wheel hub 32 radial direction expand outwardly deformation it is larger, expanded outwardly with the inner peripheral surface of wheel rim 1 in radial direction
Deformation is mutually coordinated, and wheel rim 1 is avoided to separate with the first alloy wheel hub 31 and the second alloy wheel hub 32.
Preferably, the connecting portion between the first circular ring shell 312 and the first Circular Plate 311, the first Circular Plate 311 and alloy
Connecting portion between mandrel 2, connecting portion and the second Circular Plate between the second circular ring shell 322 and the second Circular Plate 321
Connecting portion between 321 and alloy mandrel 2 is all made of arc transition.
Further embodiment according to a second aspect of the present invention, the first circular ring shell 312 of the first alloy wheel hub 31 and
The diameter of second circular ring shell 322 of two alloy wheel hubs 32 differs 5-8mm, and it is mutual in axially suit to be conducive to two fitting surfaces up and down
It does not influence, it is easy for installation.
Further embodiment according to a second aspect of the present invention, 1 internal diameter of wheel rim are 300~500mm, and flywheel rotor 1000 is most
General goal diameter is 600~900mm, and 1000 height of flywheel rotor is 500~1200mm, 1000 highest of flywheel rotor work rotation speed
