1. An assembly comprising:
a first rotor movable in rotation about a longitudinal axis of a turbomachine, the first rotor comprising a first arm;
a second rotor movable in rotation about the longitudinal axis, and comprising a second arm fixed to the first arm;
a first ring centered on the longitudinal axis, the first ring comprising a first radial flange fixedly mounted between the first arm and the second arm, the first ring having a first radially outer surface and a first radially inner surface, and the first ring comprising sealing wipers extending radially outwardly from the first radially outer surface; and
a second ring centered on the longitudinal axis the second ring having a second radially outer surface positioned facing and at a distance from the first radially inner surface of the first ring, the second ring being configured so that the second radially outer surface comes into contact with the first radially inner surface upon thermal expansion of the second ring.
