Gears
(OP)
Hi
i have a 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: Gears
1) are the input and output shafts parallel? If so it's probably not a worm drive.
2) How many shafts are there internally? Look at the casing to see how many bearings there are.
Assuming that it is a double reduction then do a cepstral analysis to identify the likely number of teeth on each gear, then fiddle around with the internal configuration until you get the right gear ratio.
It might be easier to take the inspection cover off and count the teeth.
