| 摘要 |
The invention relates to a turbine installation (1), especially a steam turbine installation. The inventive turbine installation (1) comprises at least two partial turbines (2, 3a, 3b, 3c), each of the partial turbines (2, 3a, 3b, 3c) having a rotor disk (5) that extends along the main axis. Said rotor disks (5) are rigidly interlinked to a shafting. At least one of the partial turbines (2, 3a, 3b, 3c) has an inner housing (8a, 8b, 8c) that concentrically encloses the rotor disk (5) and that is mounted so as to be axially displaceable in a bearing area (10). To allow for an axial displacement a push element (9, 9a) transmits the axial force and is linked with the inner housing (8a, 8b, 8c). In order to allow the inner housing (8a, 8b, 8c) to be axially displaced as easily as possible, the bearing area (10) has a bearing device (11) with a static friction and/or sliding friction that is so low that the axial misplacement that spontaneously occurs when the static friction is overcome during displacement of the inner housing (8, 8b, 8c) is smaller 2 mm.
