Abstract

L'invention concerne un rotor (10) de turbomachine comportant un disque (12) et au moins une aube (14) qui comporte un bulbe (18) logé dans une rainure (20) associée du disque (12), dans lequel au moins une cale (36) est comprimée radialement entre la face inférieure (32) du bulbe (18) et la face de fond (22) de la rainure (20), caractérisé en ce que la face inférieure (32) du bulbe (18) comporte deux portions latérales (38) disposées symétriquement par rapport au plan principal médian du bulbe (18), qui sont aptes à venir en appui radialement contre la face de fond (22) de la rainure (20) de manière directe ou indirecte, et en ce que ladite au moins une cale (36) réalise en outre un blocage du bulbe (18) en déplacement latéral dans la rainure (20).
