Definitions

  • Compressor rotors if possible to realize without Railunwuchten. These objects are achieved by a compressor rotor unit, hereinafter referred to only briefly as a compressor rotor, having the features according to the independent claim.
  • the toothed segment at its two (axial) ends each have a toothing about which the toothing segment is held by corresponding counter teeth on (axial) ends of the impeller segment and the terminal segment axially between the impeller segment and the terminal segment.
  • the invention means with "about” - to the toothing - "held corresponding counter teeth” that the toothing (at the axial end of a segment) and the counter-toothing (at the axial end of the other segment) are engaged, creating a positive connection to
  • the gas seal 6 can be smaller due to the smaller outer diameter of the components of the gas seal 6.

Abstract

L'invention concerne un rotor (1) de compresseur comprenant un arbre (2) à pignon présentant plusieurs segments (3, 4, 5) disposés axialement les uns derrière les autres et reliés entre eux et un joint d'étanchéité (6) en plusieurs parties étanchéifiant l'arbre (2) à pignon. Pour éviter un déséquilibre au niveau du rotor (1) de compresseur ou pour permettre un centrage si possible sans jeu d'un élément d'étanchéité (13) du joint d'étanchéité (6) en plusieurs parties, l'élément tournant avec le rotor (1) de compresseur, l'arbre (2) à pignon présente un segment de roue mobile (5) portant une roue mobile, un segment de raccordement (4) et un segment à denture (3) disposé entre le segment de roue mobile (5) et le segment de raccordement (4), lequel segment à denture (3) présente à chacune de ses deux extrémités (7, 8) une denture (9) par l'intermédiaire de laquelle le segment à denture (3) est maintenu axialement, en particulier centré sans jeu, entre le segment de roue mobile et le segment de raccordement aux extrémités (11, 12) du segment de roue mobile (5) et du segment de raccordement (4) par l'intermédiaire de dentures complémentaires (10) correspondantes, et sur lequel segment à denture (3) est disposé un élément d'étanchéité (13) du joint d'étanchéité (6) en plusieurs parties, cet élément étant relié au moins à force au segment à denture (3).
