摘要: A pressure casing has a plurality of casing shells (10a, b) which can be connected in a pressure-tight manner in a parting plane (11) by a flange (13). The casing shells (10a, b) are pressed together with sealing effect in the parting plane (11) in the region of the flange (13) by at least one threaded bolt (19; 19a-d) which extends through the flange (13) perpendicularly to the parting plane (11). A reduced thermal loading of the threaded bolts (19; 19a-d) of the flanged joint is achieved by the at least one threaded bolt (19; 19a-d) being exposed over a part of its length towards the inner side of the casing (10).

摘要: A rotor (1) of a gas turbine compressor comprises a multiplicity of welded-together rotor disks (3a, 3b, 4, 5), of which two or more rotor disks (3a, 3b), in a radially outer region (9′), are welded together, and, in a radially inner central region (9), are abutment-joined together. Via the abutment-joining of two rotor disks (3a, 3b), a heat flow (8) radially outward from the center of the rotor (1) is achieved so that the material temperature of the rotor (1) can be kept below a predetermined level during operation. As a result, the service life of the rotor (1) can be increased. In one embodiment, one rotor disk (3a), on its surface, additionally has a recess (7) which can be cooled from outside. The rotor disks (3a, 3b) according to the invention, which are welded and abutment-joined together, can especially be used at the last point in the flow direction of the compressor.
