1. In a concentric ring flywheel, the improvement comprising:
- means for eliminating gaps between adjacent concentric rings having facing surfaces and which is caused by differential expansion due to a different radius of each concentric ring,said means for eliminating gaps comprising matching circumferential steps on facing surfaces of the adjacent concentric rings and which extend along a portion of a length of the facing surface, such that said concentric rings are in contact with each other during driving rotation thereof.

Abstract
A concentric ring flywheel wherein the adjacent rings are configured to eliminate the need for differential expansion separators between the adjacent rings. This is accomplished by forming a circumferential step on an outer surface of an inner concentric ring and forming a matching circumferential step on the inner surface of an adjacent outer concentric ring. During operation the circumferential steps allow the rings to differentially expand due to the difference in the radius of the rings without the formation of gaps therebetween, thereby eliminating the need for expansion separators to take up the gaps formed by differential expansion.

6. A concentric ring flywheel without differential expansion separators, comprising:
-
a plurality of concentric rings having facing surfaces and adapted to be rotated about a common axis, each pair of adjacent concentric rings having a matching circumferential step formed in a facing surface of each of the adjacent concentric rings, said circumferential step in one of the pair of concentric rings being located in a displaced position with respect to said circumferential step in another of the pair of concentric rings, such that said pair of adjacent concentric rings are in a position with respect to each other during rotation thereof that a continuous gap extending along the length of the facing surfaces thereof is prevented from forming. - View Dependent Claims (7, 8, 9, 10, 11, 12, 13)
