A Gearbox Vibration - Fact or Fiction - Beta Machinery

2014-3-18  case study of a gearbox. Late last fall, routine monitoring of a gearbox showed an increase inoverall vibration levels, which was not apparent in the spectra. If the gearbox failed during thewinter, the process plant would not have been able to start up again until spring. Plant engineerscalled us in to determine whether the gearbox would run through the winter. The investigationuncovered problems with the way the routine monitoring was done. As well, vibration waspresent in the spectra that seemed to be unrelated to gearmesh frequency. Was there a problem
