Figure 3-7 Definition of misalignment
3.6.5.4 Alignment
The alignment of the machine is performed according to these guidelines.
1.
The machine should stand on its jacking screws
2.
Rotate the rotor and check the axial end float, see Chapter 3.6.3 Rough adjustment
3.
Mount the alignment equipment. If gauges are used, it is practical to adjust the dial gauge
in such way that approximately half of the scale is available in either direction. Check the
rigidity of the gauge brackets in order to eliminate the possibility of sag, see Figure 3-8

4.
Measure and note readings for parallel, angular and axial misalignment in four different
positions: top, bottom, right and left, i.e. every 90°, while both shafts are turned
simultaneously. The readings are recorded
