LEGO differentials and planetery gear calculations
23
November. This page was created to get a better understanding of complicated
designs with differentials and LEGO-realizations of planetery wheel assemblies.
I have built myself all these constructions, but I don't have all of them
available now for checking these formulas. So your input is more than welcome
now. After the validation of these formulas I want to go on with calculations
of torques in the behaviour of some LEGO CVT designs.

c
= b + e
a
= b - e
