MANUFACTURING METHOD OF HUB FOR FLYWHEEL

摘要

There are provided a hub for a flywheel and an energy storage flywheel. The hub for a flywheel is provided between a rotor and a rotational shaft of a flywheel to allow the rotor to have the same rotation speed as that of the rotational shaft. The hub includes a hollow main dome in which a through hole into which the rotational shaft is inserted is formed in one end and an opening is formed in the other end in a longitudinal direction of the rotational shaft, and that is formed by winding a composite material therearound; and a sub dome that is bonded to the rotor and is formed by winding the composite material around an outer surface of the main dome. Any one of the main dome and the sub dome expands in a radial direction of the rotational shaft along with the rotation of the rotational shaft and the rotor to allow the sub dome and the rotor to be maintained at a bonded state therebetween.

1. A method of manufacturing a hub for a flywheel that is provided between a rotor and a rotational shaft of a flywheel to allow the rotor to have the same rotation speed as that of the rotational shaft, the method comprising:
forming a hollow main dome in which a through hole into which the rotational shaft is inserted is formed in one end and an opening is formed in the other end in a longitudinal direction of the rotational shaft by winding a composite material therearound; and winding the composite material around an outer surface of the main dome to form a sub dome that is bonded to the rotor, wherein any one of the main dome and the sub dome expands in a radial direction of the rotational shaft along with the rotation of the rotational shaft and the rotor to allow the sub dome and the rotor to be maintained at a bonded state there between.
