It sounds like a simple problem and i know I will drive some people away by saying that i am trying to calculate the gear ratio out of a planetary-style gearbox, but that is NOT the whole story! this is very similar to a harmonic drive Norm, if the gear ratio is serious enough to justify three planetary stages, you will have to do something other than backdrive the output shaft. Seal friction on the input shaft will immobilize it. Consider manually controlled 'jog' inputs to the servomotor, or a round 'safety' handwheel on an intermediate shaft

Gear ratios and compound gear ratios. Working out simple gear ratios (two gears) A feature often requested in my gear program is that it should calculate and display the gear ratio.. The reason it does not have this feature is that the gear ratio is also the tooth count ratio (of the two gears), and that is a value that the user has to enter Standardized calculation methods such as ISO 6336 and DIN 3990 already exist to determine the load distributions on gears inside a planetary gearbox, but by their very universal nature, these methods offer varying results depending on the gearbox design. Double helical gears, in particular, can benefit from more specific, complex algorithms to.
In a conventional manual transmission (gearbox) application there are two (2) gears involved (driven and Drive) for any given gear ratio. Each gear rotates on its own shaft. These gears can only offer two (2) variations between the input shaft and output shaft, forward or reverse but the ratio remains the same.
