Title (EN) TURBOMACHINE EXHAUST CASING AND METHOD FOR MANUFACTURING SAME
(FR) CARTER D'ECHAPPEMENT DE TURBOMACHINE ET SON PROCEDE DE FABRICATION
Abstract:
(EN) The present application describes a casing (10), in particular an exhaust casing, for a turbomachine, comprising an inner hub (14) having an axis (A) of rotation and an outer annular ferrule (16) extending around the hub (14), said ferrule (16) being configured to define, with the hub (14), an annular flow path for a gas stream and being rigidly connected to the hub by arms (20a, 20b), the hub (14) comprising, at one longitudinal end, a scalloped annular flange comprising solid portions distributed at regular intervals about said axis and spaced apart from each other by hollow portions. The hub (14) is produced by assembling, by means of welding, several angular hub sectors (14') that are arranged circumferentially end to end around said axis, each hub sector (14') being connected to an adjacent hub sector (14') by a longitudinal weld bead (30) that extends over substantially the entire axial extent of the hub (14) and that is substantially aligned axially with a hollow portion of said flange.
(FR) La présente demande décrit un carter (10), en particulier d'échappement, pour une turbomachine, comprenant un moyeu intérieur (14) ayant un axe (A) de révolution et une virole annulaire extérieure (16) s'étendant autour du moyeu (14), ladite virole (16) étant configurée pour définir avec le moyeu (14) une veine annulaire d'écoulement d'un flux de gaz et étant reliée rigidement au moyeu par des bras (20a, 20b), le moyeu (14) comportant à une extrémité longitudinale une bride annulaire festonnée comportant des parties pleines régulièrement réparties autour dudit axe et espacées les unes des autres par des parties creuses. Le moyeu (14) est réalisé par assemblage par soudage de plusieurs secteurs angulaires de moyeu (14') qui sont disposés circonférentiellement bout à bout autour dudit axe, chaque secteur de moyeu (14') étant relié à un secteur de moyeu (14') adjacent par un cordon longitudinal de soudure (30) qui s'étend sur sensiblement toute l'étendue axiale du moyeu (14) et qui est sensiblement aligné axialement avec une partie creuse de ladite bride.
