small planetary gear

2021/9/13

I designed a small planetary gear using Fusion 360. Make it with 3d printer and it works very nice. With the combination of the N20 motor gearbox, it can lift about 1 Kg weight with only 1 AA battery. Hope it will give you some help. Please like and share with your friend. Thanks a lot. Have a nice day.

Final gear model parameters:

Module: 0.8
Pressure angle: 20
No. of planets: 3
Ring Gear Teeth: 42
Planet Gear Teeth: 15
Sun Gear Teeth: 12
Ratio: 4.5

You will need 5 pieces of MR63ZZ bearing and several M3 screws.
