Gear-mesh frequency

Calculate tooth-mesh frequency and one-times-speed sidebands.

Gear-mesh frequency1200.000 Hz1× sidebands: 1170.000 and 1230.000 Hz

Actual spectra depend on slip, load, bearing geometry, gear ratio and machine construction. Confirm bearing dimensions and shaft association before diagnosis.
