Abstract

L'invention porte sur un ensemble pour turbomachine comprenant : - un distributeur de turbine (40), - un carter annulaire support de distributeur (5), relié au distributeur (40), comprenant une première bride annulaire support (501) reliée à un injecteur axial (55), et une deuxième bride annulaire support (502), lesdites brides (501, 502) s'étendant axialement depuis le carter (5), - une butée (51) reliée au carter (5), et configurée pour bloquer le carter (5) en position par rapport au distributeur (40), et - des moyens de maintien (6) de la butée (51), caractérisé en ce que les moyens de maintien (6) de la butée (51) comprennent une cale annulaire (6) s'étendant radialement entre la deuxième bride support (502) et la butée (51).The invention relates to an assembly for a turbomachine comprising: - a turbine distributor (40), - an annular distributor support casing (5), connected to the distributor (40), comprising a first annular support flange (501) connected to a axial injector (55), and a second annular support flange (502), said flanges (501, 502) extending axially from the housing (5), - a stop (51) connected to the housing (5), and configured to block the casing (5) in position relative to the distributor (40), and - holding means (6) of the stop (51), characterized in that the holding means (6) of the stop (51) comprise an annular wedge (6) extending radially between the second support flange (502) and the stop (51).
