Claims (9)

  1. Rotor (1) de compresseur utilisé dans un turbocompresseur (30) à engrenage, comprenant un arbre (2) de pignon ayant plusieurs segments (3, 4, 5), disposés les uns derrière les autres axialement et reliés entre eux, et un joint (6) en plusieurs parties rendant étanche l'arbre (2) de pignon,
    caractérisé en ce que
    l'arbre (2) de pignon a un segment (5) de roue pouvant porter une roue, un segment (4) de raccordement et un segment (3) de denture disposé axialement entre le segment (5) de roue et le segment (4) de raccordement, lequel segment (3) de denture a, à ses deux extrémités (7, 8), respectivement une denture (9), le segment (3) de denture étant, par des dentures (10) antagonistes correspondantes aux extrémités (11, 12) du segment (5) de roue et du segment (4) de raccordement, maintenu axialement entre le segment (5) de roue et le segment (4) de raccordement et segment (3) de denture sur lequel est monté un élément (13) de joint (6) en plusieurs parties relié au moins par coopération de force au segment (3) de denture.
  2. Rotor (1) de compresseur suivant la revendication 1,
    caractérisé en ce que
    la denture (9) et/ou la denture (10) antagoniste est constituée sous la forme d'une denture Hirth.
  3. Rotor (1) de compresseur suivant au moins l'une des revendications précédentes,
    caractérisé en ce que
    le joint (6) en plusieurs parties rendant étanche l'arbre (2) de pignon est un joint (6) au gaz, notamment un joint au gaz simple ou double.
  4. Rotor (1) de compresseur suivant au moins l'une des revendications précédentes,
    caractérisé par
    un joint (15) à labyrinthe, qui est monté sur le segment (3) de denture.
  5. Rotor (1) de compresseur suivant au moins l'une des revendications précédentes,
    caractérisé en ce que
    l'élément (13) de joint, relié au moins par coopération de force au segment (3) de denture, du joint (6) en plusieurs parties est constitué à complémentarité de forme ou d'une seule pièce avec le segment (3) de denture.
  6. Rotor (1) de compresseur suivant au moins l'une des revendications précédentes,
    caractérisé en ce que l'élément (13) de joint, relié au moins par coopération de force au segment (3) de denture, du joint (6) en plusieurs parties a une surface (14) de joint sensiblement radiale.
  7. Rotor (1) suivant au moins une des revendications précédentes,
    caractérisé par
    un autre élément (18), monté coulissant sensiblement axialement, notamment par un ressort (19), dans un stator (17) disposé notamment sur un élément (16) de carcasse, du joint (6) en plusieurs parties et ayant une surface (20) de joint sensiblement radiale, qui est opposée axialement à la surface (14) de joint sensiblement radiale du au moins un élément (13) de joint du joint (6) en plusieurs parties, relié au moins par coopération de force au segment (3) de denture.
  8. Rotor (1) suivant au moins l'une des revendications précédentes,
    caractérisé en ce que
    le segment (3) de denture est monté sur un manchon (21) rendu étanche, notamment vis-à-vis du segment (3) de denture.
  9. Rotor (1) suivant au moins l'une des revendications précédentes,
    caractérisé en ce que
    les segments (3, 4, 5) de l'arbre (2) de pignon, ayant des segments (3, 4, 5) disposés les uns derrière les autres axialement et reliés entre eux, sont serrés au moyen d'une vis (22) de dilatation, grâce à quoi le segment (3) de denture est serré axialement entre le segment (5) de roue et le segment (4) de raccordement.
