Claims (5)

  1. Rotor ( 1 )
    comprenant au moins une aube ( 2 ) de turbine et un dispositif ( 7 ) de verrouillage pour le verrouillage axial et radial de l'aube ( 2 ) de turbine,
    dans lequel le rotor ( 1 ) comprend une rainure ( 4 ) d'aube et l'aube ( 2 ) de turbine comprend une emplanture ( 3 ) d'aube de turbine,
    dans lequel la rainure ( 4 ) d'aube et l'emplanture ( 3 ) d'aube de turbine sont constituées de manière à ce que l'emplanture ( 3 ) d'aube de turbine soit adaptée à la rainure ( 4 ) d'aube,
    dans lequel le dispositif ( 7 ) de verrouillage a une pièce ( 9 ) de serrage, qui applique une force radiale du rotor ( 1 ) à l'emplanture ( 3 ) d'aube de turbine,
    caractérisé en ce que
    la pièce ( 9 ) de serrage est monté dans une rainure ( 11 ) se trouvant latéralement dans le rotor ( 1 ),
    dans lequel la pièce ( 9 ) de serrage a une branche ( 18 ) supérieure et une branche ( 19 ) inférieure,
    dans lequel la branche ( 18 ) supérieure s'applique à l'emplanture ( 3 ) d'aube de turbine et applique à l'emplanture ( 3 ) d'aube de turbine une force dans une direction ( 29 ) radiale,
    dans lequel la branche ( 19 ) inférieure s'applique au rotor et applique au rotor ( 1 ) une force dans une direction ( 6 ) radiale,
    dans lequel la branche ( 18 ) supérieure et la branche ( 19 ) inférieure sont constituées en forme de V,
    dans lequel le dispositif ( 7 ) de verrouillage a un goujon ( 8 ) de cisaillement, qui pénètre dans un trou ( 15 ) dirigé radialement de l'emplanture ( 3 ) d'aube de turbine,
    dans lequel le goujon ( 8 ) de cisaillement s'applique à la branche ( 19 ) inférieure.
  2. Rotor ( 1 ) suivant la revendication 1,
    dans lequel le rotor ( 1 ) a un bord ( 16 ) s'étendant radialement, auquel s'applique le goujon ( 8 ) de cisaillement.
  3. Rotor ( 1 ) suivant l'une des revendications précédentes,
    dans lequel le dispositif ( 7 ) de verrouillage a un élément ( 10 ) de verrouillage pour verrouiller la pièce ( 9 ) de serrage, de manière à empêcher la pièce ( 9 ) de serrage de sortir de la rainure ( 11 ).
  4. Rotor ( 1 ) suivant la revendication 3,
    dans lequel l'élément ( 10 ) de verrouillage est constitué sous la forme d'une tôle de verrouillage disposée entre la pièce ( 9 ) de serrage et le rotor ( 1 ).
  5. Rotor ( 1 ) suivant la revendication 3 ou 4,
    dans lequel l'élément ( 10 ) de verrouillage a une saillie ( 28 ), qui est disposée dans une rainure ( 24 ) de verrouillage ménagée dans le rotor ( 1 ).
