Spectra Spectrum Motor DE - AX 15.06.2011 8:04:35

The highest amplitude of vibration on the ball mill drive was recorded in the axial position on the drive end motor bearing; with a amplitude of 7.7 mm/s rms at 60Hz. The source of the vibration emanates from the pinion gear mesh frequency (GMF) i.e. 18 teeth X 200 rpm ÷ 60 = 60Hz. However, GMF by itself is not a defect frequency.
