Planetary Reduction Gear

Number of teeth of the red gear Z1 = 40
Number of teeth of the blue gear Z2 = 38
Module m = 2 mm
The eccentricity caused by the green shaft is 2 mm.
The blue gear Z2 has rotary translational motion due to the yellow plate that has linear translational motion.
Transmission ratio i = Z1 / (Z1 - Z2) = 20
