Sep 29, 2012Registered Member I would also consider the option of torsional vibration analysis. Per example use a frequency-to-voltage converter. A magnetic pick up probes the teeth of the pinion gear of the gearbox, or the large low speed gear wheel. A simple home-made electronic F-V converter based on IC 2907 is shown in the attachement.

For example, for a gear driven by a 12-toothed pinion rotating at 10 000 rpm, an Fmax value of 360 000 cpm (360 kcpm) is most likely sufficient. If the Fmax value required is very large the resolution of the spectrum will be low, and information pertaining to low vibration frequencies may be lost.
