Abstract
The present application relates to an assembly for a turbine engine (1), comprising a first rotor (2) which is rotatable about a longitudinal axis (X-X) of the turbine engine (1), the first rotor (2) comprising a first arm (26); a second rotor (3) which is rotatable about the longitudinal axis (X-X) and comprises a second arm (36); a first sealing ring (4) which is centred on the longitudinal axis (X-X), is arranged radially outside the first arm (26) and comprises a first radial flange (40) fixedly mounted between the first arm (26) and the second arm (36); and a second sealing ring (5) which is separate from the first sealing ring (4), is centred on the longitudinal axis (X-X) and is arranged radially outside the second arm (36), the second sealing ring (5) comprising a first part (51) which is designed to come into contact with the second rotor (3), and a second part (52) which is separate from the first part (51) and is designed to come into contact with the first sealing ring (4).
