METHOD FOR ATTACHING THE COVER OF A CENTRIFUGAL COMPRESSOR OF A TURBINE ENGINE, COMPRESSOR COVER IMPLEMENTING SAME AND COMPRESSOR ASSEMBLY PROVIDED WITH SUCH A COVER

摘要

the present invention is to provide a displacement of the lid so that the centrifugal compressor between the cap and the wheel blades of the compressor remains more or less constantand as small as possible. to do this, the invention provides a configuration type in the middle of the base portion elastically deformable cover with.a lid has a casing (50) having a concave inner face (51) arranged at a distance from the compressor (12) equipped with a spinning wheel (22) fitted with blades (20) by a clip (8).the fastener (8) has a connecting end (83) in the middle of the shell (50), and a second end (82) mounted on a housing (6) of the turbomachine (1).the fastener (8) includes a diaphragm (80) in axisymmetric configuration, which presents a profile of arm (8b) is coupled to the fixing end (82) in the casing (6) by a articulaof double elbow (8c, 8d, 8e) and obtuse angle at rest.the distance between the inner surface (51) of the envelope (50) and the upper edges (21) of the vane (20) is able to be maintained in operation with a minimum set of games.
