Misalignment or misalignment Misalignment is the misalignment of the machine shaft between the drive and the follower. There are two types of misalignment.
1. Parallel or offset misalignment
2. Angular misalignment
In principle, when the machine is misaligned, it can be seen that When the shaft rotates 1 revolution, 2 shocks occur. Therefore, the unique pattern arising from the problem can be analyzed as follows.
Vibration spectrum: dominant 2X of the rotating component
Time waveform: sine waveform pattern (2X per revolution)
Phase: 180ᴼ out of phase across the coupling
