How Do I Analyze Bearings Gearbox Vibration Using
The main frequencies seen within a vibration spectra for a gearbox are the rotational speeds of each gear f i and f o and the gear meshing or the tooth mesh frequency f m The gear mesh frequency defines the rate at which gear teeth mesh together The Gear Mesh Frequency is given by latex f m= f i N i /latex or latex f m= f o N o /latex .
