Title (EN) MODULAR TURBO COMPRESSOR SHAFT
(FR) ARBRE DE TURBOCOMPRESSEUR MODULAIRE
Abstract:
(EN) The Modular turbo compressor shaft (4) comprise a tubular bearing portion (5) having a first axial end portion and a second axial end portion; an impeller portion (6) arranged at the first axial end portion of the tubular bearing portion (5); and a driving portion (7) arranged at the second axial end portion of the tubular bearing portion (5). The tubular bearing portion (5) is made of a hard material, and the impeller portion (6) and/or the driving portion (7) are made of relatively soft material compared to the hard material of the tubular bearing portion (5). The impeller portion (6) and/or the driving portion (7) are at least partially extending into the tubular bearing portion (5) and are firmly connected to the tubular bearing portion (5). The tubular bearing portion (5), the impeller portion (6) and the driving portion (7) are configured such that radial deformations, occurring during assembly of the impeller portion (6) and/or the driving portion (7) to the tubular bearing portion (5), are substantially limited to the driving portion (7) and/or the impeller portion (6).
(FR) La présente invention concerne un arbre de turbocompresseur modulaire (4) comprenant une partie support tubulaire (5) présentant une première partie extrémité axiale et une seconde partie extrémité axiale ; une partie impulseur (6) disposée au niveau de la première partie extrémité axiale de la partie support tubulaire (5) ; et une partie d'entraînement (7) disposée au niveau de la seconde partie extrémité axiale de la partie support tubulaire (5). La partie support tubulaire (5) est constituée d'un matériau dur, et la partie impulseur (6) et/ou la partie d'entraînement (7) sont constituées d'un matériau relativement mou par rapport au matériau dur de la partie support tubulaire (5). La partie impulseur (6) et/ou la partie d'entraînement (7) s'étendent au moins partiellement dans la partie support tubulaire (5) et sont fermement raccordées à la partie support tubulaire (5). La partie support tubulaire (5), la partie impulseur (6) et la partie d'entraînement (7) sont conçues de telle sorte que des déformations radiales, se produisant pendant l'assemblage de la partie impulseur (6) et/ou de la partie d'entraînement (7) à la partie support tubulaire (5), sont sensiblement limitées à la partie d'entraînement (7) et/ou à la partie impulseur (6).
