Abstract
An inertial energy storage rotor defined by a plurality of independent, concentric rotor rings rotatable about a vertical axis. A spacer ring connects each outer rotor ring to its adjacent inner rotor ring and is constructed of a substantially rigid material. The spacer ring has a cylindrical configuration and a plurality of slots which alternatingly extend from opposing axial ends of the ring towards the opposite end of the ring. The slots terminate short of such opposite end. The spacer ring includes first and second connecting tabs which are disposed at the respective axial ends of the ring for engaging and rotationally interlocking the rings, supporting the outer ring on the inner ring, maintaining the rings concentric with respect to each other, and permitting differential dilations in the rings during high rates of rotation of the wheel.
