Planetary Gearbox-Fu
Рет қаралды 6,477
2 жыл бұрынGet more out of your Split-Ring Compound Planetary Gear System with this one weird trick!
I see the same mistake (well, oversight, maybe?) repeated of unnecessarily constraining designs or making compromises because the full set of gear combinations available are just not considered or doing weird stuff with gear radius like that had something to do with the gear ratio. This seems to stem from the mindset of modifying an existing planetary arrangement rather than starting afresh with the constraints which have already been relaxed.
These designs are all published on Thingiverse www.thingiverse.com/tmackay/d...
To pick one, would probably be the “Nut Cracker” www.thingiverse.com/thing:447...

Great work.

Tell me how you’ve made this move able?

It all prints in place, but the parts can become stuck together. Just needs to be freed up after printing.

Nice! Do these also happen to be backdrivable?

They tend to be pretty high gear ratio and not backdrivable. Though I have made some smaller ones with lower ratios that can be, as long as there is no resistance on the sun gear.

@@TroyMackay Thanks! Might have to look more into it then. There's a specific design called the "bilateral drive" that somehow manages to make them easily backdrivable up to ~100:1 redution ratios.
