This video shows that 36:1 Compound Planetary Gear Assemble Process.
The compound planetary gear train (Originally Epicycle Train Gear) provides higher gear ratio than the normal planetary gear train in a small space.
The detail schematic can be found at http://www.efunda.com/DesignStandards....
In this video, 1st planetary gear set has 10:30:70 (sun,planet,ring) teeth and 2nd gear set has 17:17:51 teeth.
In the compound planetary gear train, the gear ratio can be calculated below equation.
Sun Planet Ring
1st 10 30 70
2nd 17 17 51
Ratio = (1+R1/S1)/(1-R1*P2/P1/R2) = (1+70/10)/(1-70*17/30/51) = 36.
