Extreme Reduction Gearing Device Offers an Amazing Gear Ratio

Posted by samzenpus on from the switching-gears dept.

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.

    The [lack of] precision in the bearings is much more significant than angular precision.

    You solve that with better manufacturing techniques.

    Harmonic drives are already used industrially and commercially. This is essentially a double harmonic drive driven with a planetary gearset. Nothing some good precision manufacturing couldn't create something amazing with.
