Abstract

The invention discloses a flywheel, and belongs to the technical field of flywheel energy storage. The flywheel is designed for solving the problem that a flywheel hub is prone to fatigue damage. Theflywheel comprises a polygonal hub and a flywheel outer ring, and the flywheel outer ring is arranged around the polygonal hub and connected with the polygonal hub. The flywheel outer ring of the flywheel can be connected with top points of the polygonal hub through fasteners, so that the flywheel outer ring can be fixed to the polygonal hub with very small pre-tightening force; and when the flywheel rotates, the part, between two connecting points of the flywheel outer ring and the polygonal hub, of the flywheel outer ring is separated from the polygonal hub along with centrifugal force, so that the fatigue loss of the hub is reduced, and the service life of the flywheel is prolonged advantageously.

Description

technical field [0001] The invention relates to the technical field of flywheel energy storage, in particular to a flywheel. Background technique [0002] Flywheel energy storage device is a kind of energy storage device for electromechanical energy conversion, which has broad application prospects. Among them, the flywheel is the core component of the flywheel energy storage system. In the flywheels in the related art, the hubs are almost all circular hubs, and the steel wire rope is wound on the circular hub, requiring a large pre-tightening force to press the steel wire rope on the hub, and the large pre-tightening force causes the steel wire to be easily fatigued, and the hub Also prone to fatigue and damage. Contents of the invention [0003] The purpose of the present invention is to propose a flywheel capable of reducing hub fatigue loss. [0004] For reaching this purpose, the present invention adopts following technical scheme: [0005] A flywheel comprises a ...
