4-gear offset planetary drive 1

Tooth number of:
- planet gears: 20
- fixed ring gear: 60
Gear module: 2 mm
Length of the crank = eccentric of the fixed bearing house with the ring gear, 17 mm.
N1 = 2Nc
N1: velocity of the orange gear
Nc: velocity of the crank
A successively increasing/decreasing space (suction/compression) is formed on either side of the ring gear and planet ones so the mechanism can be used for pumps.
