Abstract
La présente invention se rapporte à un carter d'échappement (100) pour turbomachine comprenant un moyeu (4), une virole extérieure (6), des bras de raccord (24), ainsi qu'au moins une ferrure de passage d'efforts (20) destinée à l'accrochage du carter sur un élément extérieur (22). Selon l'invention, l'un des bras (24) comprend au moins un organe structural (28) s'étendant dans une direction donnée entre le moyeu et la ferrure (20), cet organe (28) traversant la virole (6) d'une manière autorisant localement un déplacement relatif, au moins selon la direction donnée, entre d'une part l'ensemble solidaire formé par l'organe structural (28) et la ferrure (20), et d' autre part la virole extérieure (6).The present invention relates to an exhaust casing (100) for a turbomachine comprising a hub (4), an outer ferrule (6), connection arms (24), as well as at least one force passage fitting. (20) intended for hooking the casing onto an external element (22). According to the invention, one of the arms (24) comprises at least one structural member (28) extending in a given direction between the hub and the fitting (20), this member (28) passing through the ferrule (6) in a manner allowing locally a relative displacement, at least in the given direction, between on the one hand the integral assembly formed by the structural member (28) and the fitting (20), and on the other hand the outer shell (6).
