Downside be provided with flywheel assembly annular groove, flywheel mounting ring slot position is in the outer ring of flywheel hub；The yoke plate is fixed at winged
On the upper surface for taking turns wheel hub, multiple permanent magnet fitting grooves, outer ring of multiple permanent magnet fitting grooves around yoke plate are provided on yoke plate
Shape array；The retaining ring is fixed at the outer ring of yoke plate, and retaining ring closes the outside of permanent magnet fitting groove.
Preferably, the flywheel hub and retaining ring are non-magnetic nonmetallic materials.
Preferably, the outer diameter of the flywheel hub is equal with the internal diameter of the outer diameter of yoke plate and retaining ring, the following side of retaining ring
It is fixedly connected by screw with the outside portion of flywheel hub.
Preferably, the top of the retaining ring is higher than the upper surface of yoke plate, is provided with multiple air gaps on retaining ring, multiple air gaps around
Retaining ring annular array.
Due to the application of the above technical scheme, the utility model has the advantage that compared with prior art
The permanent magnetism mounting structure of the energy accumulation device for fly wheel of the utility model, include flywheel hub, yoke plate and retaining ring,
