Abstract

Clinquant pour aube mobile de turbomachine, ensemble pour rotor comportant un tel clinquant et procédé de montage d’un tel ensemble L’invention concerne un clinquant (300) pour aube mobile (10) de turbomachine, configuré pour être monté entre le pied (20) de ladite aube mobile et une cavité de disque (41), le clinquant comprenant : une première surface latérale (320a) s’étendant le long d’un premier flanc latéral (22) du pied de l’aube, une deuxième surface latérale (320b) s’étendant le long d’un deuxième flanc latéral (22) du pied de l’aube, et une surface inférieure (310) s’étendant le long d’une face inférieure (21) du pied de l’aube mobile, reliant la première surface latérale (320a) à la deuxième surface latérale (320b) et comportant au moins un bossage (330) s’étendant radialement dans une direction opposée au pied de l’aube. L’invention concerne aussi un ensemble pour rotor de turbomachine, comportant un pied d’aube mobile (20), une cavité de disque (41) et un clinquant (300), le clinquant étant monté dans la cavité du disque avant le pied d’aube. Figure à publier avec l’abrégé : Figure 4Foil for a moving blade of a turbomachine, assembly for a rotor comprising such a foil and method for mounting such an assembly The invention relates to a foil (300) for a moving blade (10) of a turbomachine, configured to be mounted between the root (20) of said moving blade and a disk cavity (41), the foil comprising: a first lateral surface (320a) extending along a first lateral flank (22) of the root of the blade, a second lateral surface (320b) extending along a second lateral flank (22) of the root of the blade, and a lower surface (310) extending along a lower face (21) of the root of the moving blade, connecting the first lateral surface (320a) to the second lateral surface (320b) and comprising at least one boss (330) extending radially in a direction opposite to the root of the blade. The invention also relates to an assembly for a turbomachine rotor, comprising a movable blade root (20), a disk cavity (41) and a foil (300), the foil being mounted in the disk cavity before the blade root.
