Abstract

Ce carter est destiné aux compresseurs utilisés dans les turbomoteurs tels que les moteurs à turbine à gaz. Il comprend des carters annulaires interne et externe espacés radialement Celui interne est pourvu d'une pluralité d'aubes de stator faisant saillie en direction du centre du carter interne et comprenant une ou plusieurs joues faisant saillie vers l'extérieur en direction du carter externe, la joue, ou chaque joue, comprenant une partie s'étendant dans une direction le long de l'axe du carter externe et définissant en fait un ergot de positionnement Celui externe est pourvu d'un évidement dans lequel l'ergot,- ou chaque ergot, vient coopérer, et l'ergot et l'évidement, ou chaque ergot et chaque évidement, étant construits et disposés l'un par rapport à l'autre de manière que le carter externe puisse être passé au-dessus du carter interne à partir d'une de ses extrémités pour venir coopérer avec l'ergot, ou chaque ergot, dans l'évidement, ou chaque évidement, puis être déplacé axialement par rapport au carter interne pour fixer le carter interne et lui interdire tout mouvement dans des directions radiales.This casing is intended for compressors used in turbine engines such as gas turbine engines. It comprises radially spaced internal and external annular housings The internal one is provided with a plurality of stator vanes projecting towards the center of the internal housing and comprising one or more flanges projecting outwardly towards the external housing, the cheek, or each cheek, comprising a part extending in a direction along the axis of the outer casing and in fact defining a positioning lug The outer one is provided with a recess in which the lug, - or each lug, comes to cooperate, and the lug and the recess, or each lug and each recess, being constructed and arranged with respect to each other so that the outer casing can be passed over the internal casing to starting from one of its ends to come to cooperate with the lug, or each lug, in the recess, or each recess, then be displaced axially with respect to the internal casing to fix the internal casing and prevent it from any movement in radial directions.
