Hi Non-Twisty Puzzles fans,

Variomatic Gears is the first of three experiments with non-circular gears. It is a set of gears with a varying gear ratio. At first, both gears make a quarter turn, which corresponds to a 1:1 gearing ratio. Then, one gear turns by 90 degrees, while the other turns by 180 degrees, corresponding to 1:2. Next the roles reverse to 180:90, which is 2:1. So this set of gears could be described as having a 1-1-2:1-2-1 gearing ratio. The total adds up to 360:360, so the two gears have a 1:1 gearing ratio at average.

This gearing mechanism was inspired by the Heart-Shaped Gears jewels by Guofeng Guan.

Watch the YouTube video.
Buy the puzzle at my Shapeways Shop.

Check out the photos below.

Enjoy!

Oskar

Very interesting, I can't wait to see this applied to a puzzle. BTW, do both gears have to be identical for this to work?

No, but that symmetry helped a bit with the design.

Never mind a puzzle, it would be a lot of fun to drive a car with these gears in the engine! :lol:
