Abstract (en)

[origin: EP1845235A1] The device has a rotor disk (1) with a radial face that presents an annular recess (6) defined by a set of walls. An annular flange (3) presents an annular base pressing against a radially outer wall of the recess. A split annular retaining ring (7) is disposed in the recess, and includes a radially outer face. The outer face presents an annular setback such that a radial force that results from a face (4) bearing against a radially inner face of the base of the flange is situated in a plane that is offset axially relative to a radial plane passing through a center of gravity of the ring.
