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.
