Turbogroup of a power generating plant

摘要

The present invention relates to a turbogroup (1) of a power generating plant. A turbine unit (2), has a turbine (4) and a further fluid-flow machine (6) on a common turbine shaft. A generator unit (3), has a generator (8) on a generator shaft (9). The turbine shaft (5) and the generator shaft (9) are connected to one another. A third radial bearing unit (13) supports the generator shaft (9) on a side of the generator (8) which faces the turbine unit (2). A thrust bearing unit (16) supports the turbine shaft (5) axially between the generator (8) and the additional fluid-flow machine (6). A first radial bearing unit (11) and/or a second radial bearing unit (12) have/has pendulum supports (20) which are in each case supported on a bearing pedestal (21). At least one of the pendulum supports (20) is supported on the associated bearing pedestal (21) via a spring element.
