A QUICK INTRODUCTION TO BEARING ENVELOPE ANALYSIS

Because the vibration signals of a faulty bearing are small compared to shaft order and gear mesh frequency, detection of faults at the bearing rate frequencies using Fourier analysis is difficult. Fault detection at the baseband frequencies of the bearing rate is “Stage 1” fault detection. Bearing faults detected using these types of analysis are Late Stage; the bearing can be close to ...
