Fergusons Paradox of Gear Drive

Input: pink carrier.
Output: yellow gear.to balance forces applied to the input and output by using two planetary gears (in blue and green).
Zf: tooth number of stationary grey and brown gears. Here Zf = 41.
Zy: tooth number of yellow gear. Here Zy = 40.
Transmission ratio i = (Zg – Zf)/Zg. Here i = 1/40
The yellow gear is a standard one.
The grey and brown gears are of corrected tooth profile.
It is possible to use more planetary gears by the same way.
