Patent
CA 2457892
The invention concerns a housing (21) comprising an outer casing (22) provided with hooks (24) for supporting stator rings (26) and sealing rings (27); the hooks (24) are angularly discontinuous and assembled at the casing (22) by mortise-and tenon joints (28, 29). Thus the hooks and the casing can be of different constructions, that of the hooks being heat-resistant and the other being more amenable to machining and forming. Ventilation, clearance control and thermal protection are facilitated.
Un carter (21) comprend une enveloppe extérieure (22) munie de crochets (24) de support d'anneaux de stator (26) et d'étanchéité (27) ; les crochets (24) sont discontinus angulairement et joints à l'enveloppe (22) par des assemblages à tenon et mortaise (28, 29). Les crochets et l'enveloppe peuvent ainsi être construits en matières différentes, celle des crochets résistant bien à l'échauffement et l'autre se prêtant mieux à l'usinage et au façonnage. La ventilation, le pilotage des jeux et la protection thermique sont facilités.
