Abstract (en)
[origin: EP0937864A2] The machine has at least one blade ring (14,15) formed as a self-supporting component with a mainly rotary-symmetrical stiffening (20,21) along the inner cover plate (16,17), to protect it against axial deformation. The outer cover plate (18,19) is segmented and has several joints. The blade ring is positioned in the housing (13) via at least three segments of the outer plate using a bearing unit (24,25,26,27), which permits a local relative movement. An air guide shell (3) between housing and outer cover plate guides a cooling air flow along the inside of the housing. It has openings (31,32) for the housing-fastened bearings (26,27) of the blade ring. The openings permit passage of the part of the air flow towards the cover plate.
