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.

 
 

a ,c and b are angular velocities

a + c = 2b

adder/subtracter of angular velocities

a + c = 2b

(-a) + c = 2e

 

c = b + e

a = b - e

 

planetery wheels

-a + 3c = 4b

 

 

planetery wheels

a + 3c = 4b

 

planetery wheels

a + 4c = 5b
