ABSTRACT:
A rotary energy storage device comprises a rotor and a hub for mounting the rotor on a shaft. The rotor is joined to the hub by an interlayer disposed between the rotor and hub. One surface of the interlayer is bonded to a mounting surface of the hub. A second surface of the interlayer, which is opposite the first surface, is bonded to a surface of the rotor which is opposite and spaced from the mounting surface of the hub. Due to differences in their constructions, such as their relative dimensions, the rotor and the hub experience different strains due to the centrifugal forces exerted during rotation of the energy storage device. The difference between the strain at the mounting surface of the hub and the strain at the opposed surface of the rotor induces a shear stress in the interlayer. To accommodate the induced shear stress, the interlayer has a thickness and a shear modulus which permit the interlayer to deflect in response to the difference in strains without structural or bond failure. The interlayer can be effective to accommodate the induced shear stress at any speed of the energy storage device up to the speed at which the rotor would fail due to centrifugal loads imposed upon it. The interlayer is preferably formed of a body of elastomer and is preferably bonded to the hub and rotor adjacent an area of maximum strain differential between the hub and rotor.
