Bearing & Gearbox Vibration Analysis Using Demodulation Techniques (Part 1)

Bearings and gearbox vibration are fundamental issues for rotating machines in many industrial applications. These are critical components; any failure can prove expensive in repair costs and downtime. Because of…

Bearing & Gearbox Vibration Analysis using Demodulation Techniques? (Part 2)

In our previous post on this subject we briefly looked at how we can use the detailed design information of bearings and gearboxes to look for specific fault conditions by collecting vibration information and analysing their frequency spectra. Amplitude modulation of the vibration signatures is common and we have seen how this causes side-bands to be present in the frequency domain.
