Where Time Domain Plots Can Be Invaluable
Obviously, time domain is a powerful tool. But what kinds of problems and situations are better analyzed with the time domain plot ?
 
  • Slow Beat Frequencies
  • Impacts
  • Transients
  • Rubs
  • Chipped / Broken Gear Teeth
  • Amplitude Modulation
  • Frequency Modulation
  • Slow Speed Bearing Defects
Additionally, you can gather information related to the machine condition such as:
  • Misalignment
  • Looseness
  • # of Teeth on a Gear
  • Eccentricity
  • Waveform Shape
  • Instabilities
Let's see how the time domain can be of help with some of these.
