How to determine gear mesh frequency

WebApr 2, 2014 · Frequency is defined as Hertz (Hz) [cycles / sec.]. For the gear meshing it can be calculated by number of teeth * rotational speed [rpm] / 60. Gear meshing frequency is a harmonic phenomenon and its harmonics can be found by multiplying fundamental meshing frequency by whole numbers (1, 2, 3…). 2 / 10 http://blog.prosig.com/2014/05/01/bearings-gearbox-analysis-using-demodulation-techniques/
