Internal ferrule of an intermediate casing, associated intermediate casing with lamellae forming shock absorbers

摘要

The invention relates to a rectifier assembly (30) of a turbomachine, comprising: - an internal ferrule (10) of a casing comprising, from an axis of rotation of the turbomachine, a radially external surface (11) comprising an alternation of slots (12) and cross members (13), the cross members (13) extending axially, - at least one straightening blade (4) comprising a blade root (41) arranged in a slot (12); - at least a strip (20) comprising a central part supported by the cross member and side parts (22, 23) extending from the central part and suspended in the slots (12) surrounding each cross member; - at least one fin (5) comprising a platform (51) disposed above each cross member (13); each cross member (13) comprises a notch forming a radial recess in the cross member (131) and formed in the middle of the cross member (13) taken in an axial direction, the notch supporting said strip (20), each strip (131 ) being able to be deformed by a blade root (41) so that the central part is deformed to fill a radial play between the cross member and the fin (5) disposed between each blade.
