1. In an inertial energy storage wheel having at least one rotor, the rotor including an axially oriented end face and a plurality of radially oriented grooves in the end face, a plurality of radially oriented connecting members having a shape complementary to a shape of the grooves and disposed therein, the connecting members protruding in a radial direction past the grooves, and mounting means radially spaced from the rotor and attached to the connecting members for the transmission of rotational forces between the rotor and such means, the improvement to the rotor and the connecting member comprising:

  • a connecting member having diverging sides extensions of which generally intersect at an axis of the rotor, and a groove in the rotor having side walls which diverge in accordance with the sides of the connecting member to form a snug fit between the sides and the side walls when the rotor is at rest, the divergency of the sides and of the side walls having a magnitude and an orientation such that upon dilation of the rotor during its rotation, the rotor and the connecting members are permitted to move with respect to each other in a radial direction while the sides and the side walls of the connecting members and the grooves, respectively, remain in mutual contact and engagement and maintain their snug fit.
