Turbomachine rotor disc

Abstract

This disclosure relates to a turbomachine rotor disk (30) comprising a cavity (31) configured to house a blade root (41) of a movable blade (40) and a shim (50), the cavity (31) comprising: - a first cavity (311) opening onto a radially external periphery (S1) of the rotor disk (30) and which is configured to house the blade root (41) and the shim (50), and - a second cavity (312) arranged such that the first cavity (311) and the second cavity (312) are radially separated from each other by two first bearing surfaces (32a, 32b) of the rotor disk (30) which extend circumferentially respectively from two opposite circumferential end faces (S2a, S2b) of the cavity (31) facing each other so as to define between them a longitudinal opening (33) which opens on one side into the first cavity (311) and on the other side into the second cavity (312).
