Extreme Reduction Gearing Device Offers an Amazing Gear Ratio

ErnieKey writes: The 3D printed extreme reduction gearing device, created by long-time puzzle maker M. Oskar van Deventer, may leave you puzzled for its obvious applications, but the coaxial cranking mechanism offers potential in a variety of real-world applications with multi-colored gears that move in opposite directions at a ratio of 11,373,076 : 1. This 3D printed reduction gearing device is compact and multi-colored, and looks deceivingly simple at first glance. Developed through a complex algorithm, it could possibly offer potential as parts for machines like 3D printers, aerospace and automotive components, as well as perhaps robotics and a variety of motors.

... Everything I do is more creative than this. Just because you have no clue that this isn't impressive doesn't magically make it so.

I know how it works, there is nothing new about it. The video doesn't demonstrate anything new or uncommon, the only uncommon part about it is that he used shitty ratios that would break the instant it wasn't free wheeling. You can not use 5 tooth pinions if you want to do anything more that a free wheeling toy.

Hint: LOTS OF THINGS SMALLER CAN EASILY BEAT THAT RATIO GIVEN THE SAME CONSTRAINTS. Those things are just worthless in a lot of cases.

Open up a old school watch. That's impressive. Then get back to me about how compact this thing is for its ratio. Combine any two hand wound mechanical wrist watches, just the gears between hours and seconds, your already at 1:12M, and many times more "compact"

Get a clue before you make an ass out of yourself next time.
