Assembly comprising a foil mounted on a disc of a moving wheel

An assembly comprising:

• a disc of a turbomachine movable wheel comprising:
• an axis of rotation,
• teeth each comprising, on either side, a first side surface and a second side surface
• notches between each tooth,
• one bottom surface per notch connecting the first side surface of one tooth to the second side surface of the other neighbouring tooth forming the notch therebetween,
• a first radial surface and a second radial surface formed on either side of the disc delimiting the notches and teeth,
• at least one shim mounted in a notch, comprising an outer surface partly covering the surfaces delimiting the notch, the shim comprising:
• a base in contact with the bottom surface,
• a first side leg and a second side leg connected together via the base, each of the side legs being in contact with a part of the first side surface of a tooth delimiting the notch and with a part of the second side surface of the other tooth delimiting the notch respectively,
• a first axial holding element for the shim abutting against the first radial surface to retain the shim in the notch in the axial direction of the disc of the movable wheel.
