I have a question about these kinds of drives. Don't these depend on the fact that no one is moving and wiggling the whole mechanism? It seems to me like if the red gear with the slots were to move just a bit out of the way, it'd mess up the entire mechanism.
- jorgem 13y agoI dunno, but the article says the mechanism was used commonly in watches -- which move and wiggle quite a bit.
- Jtsummers 13y agoThe red gear is held in place via the axle, and isn't free to rotate because of the crescent shaped portion on the drive wheel. The spoke on the drive wheel catches the driven wheel before/simultaneous to the crescent rotating out of the way and freeing the driven wheel to move.
- makmanalp 13y agoOh wow, I see now. The green circular part pretty much locks the crescent and thus the red gear into place. That's why there is a gap in the circular part where the gear is supposed to turn. Thanks!
