Abstract:
1. A method for checking a bearing alignment of a rotor of a gas turbine or steam turbine, for a rotor arranged in a bearing shell and having a radial offset and a radial offset surface, and the bearing shell, with a radial end surface, at least in sections supporting the rotor, the radial offset surface and the radial end surface being arranged at a free end of the rotor, the method comprising: measuring a degree of offset in an axial direction of the rotor, between the radial offset surface and the radial end surface at at least two different circumferential positions around a rotor periphery; and using differences in the degree of offset at the at least two different circumferential positions as measurements to determine the alignment of the rotor relative to the bearing shell.
