Wedge for a moving turbine blade of a turbomachine

Abstract

This disclosure relates to a shim (50) for a movable turbine blade (40), the movable turbine blade (40) comprising a blade root (41) housed in a recess (31) of a turbine rotor disk (30), the recess (31) comprising a first cavity (311) and a second cavity (312) arranged radially separated from each other by two first bearing surfaces (32a, 32b) of the rotor disk (30) arranged circumferentially opposite each other so as to define a longitudinal opening (33) between them, the shim (50) comprising a flexible body, a first pad, a second pad and a third pad, the shim (50) being configured such that, in an assembled configuration, the first pad bears against the blade root (41), the second pad bears against the first two bearing surfaces (32a, 32b), the third stud passes through the longitudinal opening (33) into the second cavity (312).
