TEETH NUMBER?

TEETH NUMBER?

TEETH NUMBER?

(OP)
thankyou very much (Reb,Hatch,sack ..all)for your  answers it was very helpfull
i have another doubts as im monitoring this gear box i have the follwing data
                  400/800 HP   

                  450/900 RPM INPUT
                   20/40 RPM OUTPUT
                   22:1 REDUCTION
is there a way of finding the teeth number on each gear?
i have data results (FFT) and i dont want to interpret it before getting the right input
any help would be very much apreciated
thankyou.

RE: TEETH NUMBER?

Depending on the condition of the gearbox, the FFT should be able to give you the number of teeth.  A good gearbox will have a clearly defined peak at the N times run speed freq, where N is the number of teeth.
