1x11million gear reduction
Those wacky Germans, always goofing off!

You're right, I just now caught the name. I SO VERY MUCH wanted this guy to be German!
Okay, those wacky Dutchmen! (But I love the concept, and he's got a bunch of these vids!)

So if you hooked up a 1/100th HP motor at about 15,756 rpm you get out about 36,300 lb-ft of torque.

Can it core a apple?
Might come in handy timing my laps at VIR. Bill K

Yes- there is an apple coring attachment. By the time it's done, the apple is rotten.

No, he has a 3D printer. ...AND way too much free time.
![]() Really nothing new there, from a mechanical design POV.

I got one, very handy.

This contraption is on display at MIT muesem
13.7 billion years per revolution on the output shaft https://www.youtube.com/watch?v=VCA2whpMCno

does it work either way? So he has to spin that driver gear 11mm turns to get 1 revolution out of the driven gear... why not turn the driven gear to move the driver to a ridiculous speed?

![]() The point is that a mechanism that could take advantage of that much torque would be severely limited by an enormous amount of torque from even some of the smallest motors. Which would obviously be a crippling factor in how it is mounted, internal construction, how it is coupled to a load, etc if it was used as a transmission. Now of course it could possibly be used for some kind of super precise indexing or something related. |

I melted some lego technic pieces with a mass of lego gears trying to see what sort of RPM I could hand crank. There was a limiting torque of the axle pieces breaking on the input, and a limiting speed of melting the output axle.

so the once 'driver' gear becomes the 'driven gear, that thing must hit light speed when you turn the 1/1.1mm gear? Make that out of a serous alloy and you have the ultra centrifuge that the world has never seen!

It is difficult in practice to use things like this as step up gear boxes. Even a tiny amount of friction at the output would require absurd torque to overcome. The gears are more or less self locking at some point as increasing the torque increases the normal force between the gears and the required torque is always more than you can apply.
Think of a nut and all thread. You can spin the nut up and down the thread with a huge mechanical advantage. However it is difficult to push on a nut to rotate the threaded rod unless the thread is course and very low friction

Burn the fire.

You should have lubricated it with a lego driven oil pumping system.
