Abstract
The disclosure refers to a method and apparatus for checking the bearing alignment of a rotor of a gas turbine or steam turbine having a rotor with a radial offset and a radial offset surface and in a bearing shell, which supports the rotor, with a radial, at least in sections, end surface, wherein the radial offset surface and the radial end surface face the free end of the rotor. The radial offset is arranged in the bearing shell and offset towards the free end of the rotor. The degree of offset in the axial direction with regard to the rotor is measured at least two different circumferential positions around the rotor periphery in order to determine the alignment of the rotor. Differences in the degree of offset at different circumferential positions are used as measurement for the bearing alignment.
