I made
this handy motor / gearbox reference sheet that has most of the equations you need for gearbox calculations.
If you want more specific numbers (factoring in things like ideal voltage vs. actual voltage, COF, etc.) you will need to find some of the other reference sheets here on CD. If that is what you are after trying searching for "Motor Data" or "MCALC". If you can't find the right thing, I can probably link them for you.
