Abstract (en)

The invention relates to a rotor device (1) for a steam turbine, which is rotatably mounted around an axis (2), comprising a number of blades (3) arranged at the rotor device (1), comprising a first portion (4) of the peripheral surface of the rotor device (1) being constructed to receive an inner casing (5) having a steam inlet (6) of said steam turbine, comprising a loose balance piston (7) mounted at a second portion (8) of the peripheral surface of the rotor device (1), whereby the diameter of the first portion (4) of the peripheral surface of the rotor device (1) is larger than the diameter of the second portion (8) of the peripheral surface of the rotor device (1). The invention further relates to a steam turbine, comprising that kind of rotor device, an inner casing (5) mounted at the first portion (4) of the peripheral surface of the rotor device (1) or at the circumferential restraint (9), whereby the inner casing (5) has a steam inlet (6), an outer casing and axial bearings (10) for bearing the rotor device (1) in the inner (5) and/or outer casing.
