Keep These Principles In Mind While Choosing Your Parameters. If You Don'T, Your Gearbox Will Be Useless. R = Amount Of Teeth In The Ring P = Amount Of Teeth In The Planets S = Amount Of Teeth In The Sun Equations 1. Ratio = Incoming Speed / Outgoing Speed = (R + S) / S => R = (Ratio - 1) * S 2. P = (R - S) / 2 = Whole Number Use The First Equation To Determine R And S, Do This By Fixing The Ratio And Find The Smallest Combitination Of R And S That Fits The Second Equation. Keep In Mind That If R Is Even, S Should Also Be Even, Else The Second Equation Will Never Be Satisfied. Another Important Tip Is That When You Set The Ratio Too High, The Planets Will Become To Big And The Sun Will Be Too Small. Also, Don'T Make The Amount Of Teeth On The Gears Much Lower Than 10. Example: I Require A Ratio Of 3.5. I Choose S = 10, Which Gives Me R = 25. According To Equation 2, P = 7.5, Which Is Not Allowed. I Try S = 12, Which Gives R = 30 And P = 9, Which Is Allowed.
