Abstract (en)
The turbine has a shaft (6) formed as a hollow shaft with an axial drill hole (8) flow throughable by a cooling medium (14). The cooling medium is pressed outwardly on a wall of the drill hole due to the centrifugal acceleration caused by the rotation of the shaft. A set of radial channels is inserted at ends of the drill hole in the shaft to supply or remove the medium and fluidic connectable with a storage for the cooling medium. An independent claim is also included for a method for cooling of a rotatably supported shaft of a steam turbine.
