Theory of Alignment

• Why alignment is important
• Alignment terminology
• Principles of shaft alignment.
• Coupling types
• Tolerance and speed

Types of Misalignment

• Offset and angular misalignment
• Alignment of Sheaves/Belts drives

Diagnosing Misalignment

• Misalignment & time waveform
• Misalignment & freq. spectrum
• Phase angle and misalignment
• Misalignment vs. unbalance
• Misalignment vs. eccentricity
• Misalignment vs. bent shaft
• Cocked bearing and looseness

Instrumentations
