Abstract
A rotor of self-supporting type for a turbo-machine. The rotor comprises a plurality of axially spaced discs which are interleaved with spacing rings and with the assembled combination of discs and rings held together by through bolts. Each spacing ring is provided on each opposed face with an annular shoulder which mates with a cooperating annular shoulder on an opposing face of an adjacent disc so as to prevent relative radial movement among the assembled discs and rings. A portion of each ring extends radially inwardly of its annular shoulders and is provided with a thickness in the axial direction which is less than the spacing between the opposing surfaces of the adjoining discs.
