-60:1 Compound Planetary Gear Reducer

thingiverse

Torque Capabilities Please understand that I designed this gearbox for a demonstration model so it would be easy for everyone to comprehend how a compound planetary works, that's why I omitted the third module that increases torque capabilities. Because of that, this gearbox cannot handle much load. How This Works - 60 turns of the input sun gear will result in ring gear #2 making one full rotation in the opposite direction. These are designed to be able to mount them in series on the channel or drive them with the included stepper motor mount. You will need to scale the channel longer if you want to use two gearboxes and the stepper motor mount on the same channel, but keep in mind it is very boring to watch the second gearbox rotate as it is very slow. - This gearbox cannot be back-driven every piece of plastic on it will snap before you get the input to turn. Compatibility - This gearbox is the exact same form factor as my 1379:1 gearbox and the 100:1. The mounting channel and back cover are exactly the same parts but keep in mind that the gears themselves are incompatible. Gears Used: Planets: 6 - Planetary Gearset #1 (Input End) Tooth Module = .8730 - Sun = 29T - Planets = 16T - Ring = 61T - Planetary Gearset #2 (Output End) Tooth Module = 1.8707 - Sun = 13T - Planets = 8T - Ring = 29T Other Important Info: CAD Files?? - I included the Fusion 360 project with this, but the most recent version of this project can be downloaded in lots of different formats from this link: http://a360.co/2B4BlRn - Feel free to create your own modifications and parts for this project, and if you do, make sure you create a remix and upload them I'll link to them possibly creating a collection for all of them! Show Your Work! - Make a "make" and show everyone what you made! Everyone will thank you for it!
