Tooth number of:

- ring gear: 60

- other gears: 20 Gear module: 2 mm

Length of the crank = eccentric of the fixed bearing house with the orange gear, 17 mm.

N2 = (2/3)Nc

N2: velocity of the ring 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.
