<p>A first turbine rotor hub (32) and a second turbine rotor hub (42) each have respective internal splines (52,62) which engage coaxial, non-concentric external splines (54, 64) on a shaft (20) and are in thrust bearing relationship cooperating, circumferentially disposed, radially inwardly extending lugs (35, 45) on each hub (32, 42) define radially inwardly extending projections (80). A resilient split metal band (60), having circumferentially disposed apertures (61) overlies the projections (80) which extend through the apertures (61). The uninstalled diameter of the band is greater than the installed diameter such that the band is self-retaining. The assembly requires no bolts between the rotor stages (30) and (40) to hold the two stages together.</p> |
