small planetary gear
Description
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.
