PURPOSE:To provide the subject fly-wheel wherein spoke extendable between the circular ring shaped outer wheel and rotary shaft constituting a part of the rotary energy storage portion are provided, thereby to increase the rupture strength of the fly-wheel. CONSTITUTION:An each of hexagonal spokes 4 is provide between an outer wheel 3 made of a F.R.P. material and an inner wheel 2 made of the same material, thereby to connect the outer wheel 3 to the inner wheel. The fly-wheel rotates and the spoke 4 extends by the centrifugal force, and the quantity of extension thereof is equal to or slightly larger than the quantity of radial extension direction of the outer wheel 3. Accordingly, the outer wheel 3 receives the pressing force from the spoke 4, and lowers the radial stress generated in the outer wheel 3. A dead weight 13 is fitted and the quantity of extension can be adjusted. The balance of the full part of the rotary body can be adjusted by the adjusting dead weight 14. |
