Abstract:
A method for alignment of a shaft (W1) of a rotating machine (M1), which is supported at predetermined mounting points (6) on a base, in a predetermined three-dimensional nominal position by moving the machine (M1) on the base, comprising:(a) detecting an instantaneous position of the shaft (W1) with respect to the nominal position by sensor device means providing electrical position signals corresponding to the difference between the instantaneous position of the shaft (W1) and the shaft nominal position,(b) calculating by means of a computer (main computer or alignment computer) correction values for position corrections to be made at each of the individual mounting points using the position signals, the know position of the mounting points (6) with respect to the predetermined reference points on the base and other geometric machine data and/or geometric measurement data related to the base in order to achieve the shaft nominal position, and(c) providing an alignment technician who will make the position correction with the magnitude and direction of the correction value for each mounting point (6),wherein the current correction values for the individual mounting point (6) are transmitted to the alignment technician (4) acoustically.
