Abstract
An annular rotor defined by a plurality of arcuate segments arranged in end to end relationship to form a friction disc. The arcuate segments are held in relatively loose annular formation by a retaining ring provided with opposite side plates fixedly secured thereto and between which radially extending projections of the arcuate segments extend. Ths side plates are provided with flange or tang portions which mate with recesses formed in opposite sides of the projections to thereby secure the segments to the ring in relatively loose formation to permit thermal expansion of the segments with minimal distortion thereof. If desired, the segments may each be provided with a recess in the unsecured peripheral edge thereof which recesses in aligned form provide a substantially continuous annular recess adapted to receive a flexible ring which, in turn, maintains alignment of the segments in a common plane.
