Patent

CA 2548489

The invention relates to a turbo machine, more particularly a gas turbine. The turbomachine has a stator and a rotor, wherein the rotor has blades (21) and the stator has a housing (20) and stationary guide blades (17), wherein said guide blades (17) form guide blade crowns (11, 12) adjoining the housing (20) with ends (18) located radially on the outside and the rotor with ends located radially on the inside. The guide blade crowns are spoke-centered with the aid of bearing journals or guide pins (24) assigned to the housing (20) and penetrating said housing (20). According to the invention, the guide pins (24) extend approximately perpendicular to the housing (20), wherein the ends (26) of the guide pins (24) penetrating the housing engage in the forked elements (27) assigned to the ends (18) located radially on the outside of the guide blade crowns (11, 12).

L'invention concerne un turbomoteur, notamment une turbine à gaz, qui comprend un stator et un rotor, le rotor étant doté d'aubes (21) et le stator étant pourvu d'un carter (20) et d'aubes fixes (17). Les aubes fixes (17) forment des couronnes (11, 12) dont les extrémités radiales externes (18) sont contiguës au carter (20) et les extrémités radiales internes sont adjacentes au rotor. Les couronnes d'aubes fixes sont centrées par rayons au moyen de tourillons ou de chevilles (24) associés au carter (20) qu'ils traversent. Selon l'invention, les chevilles (24) sont pratiquement perpendiculaires au carter (20), et leurs extrémités (26) qui pénètrent dans le carter sont en prise avec des éléments (27) fourchus associés aux extrémités radiales externes (18) des couronnes (11, 12) d'aubes fixes.
