Paradoxical gears....

[Izzy]

Not chain drive joe. Based on priciest of cirles. It's 3d or rather has length to grantee there is no dead zone where a off center circle would simply pull away from the mating.
Item.
There us a gear reduction effect - note that the primary driven is a single loan and the left is twin while the ri h ht has three. But it is not a 1:2 and 1:3 ratio box.


As for uses not sure. Maybe a supercharger that does not require a gear set to keep in time. Therefore quiet.
