Gear System That Changes Direction

Gears are fascinating mechanical components and they have different size, shape, function and forms. It is sometimes to difficult or time consuming to make animations of a gear or mechanical component composed of gears, yet I wanted to show demonstration of these kind mechanism in my web site. This was a time consuming process, but the final result pleased me, and I hope you enjoy it as much as I did.

In the video above we can see very clever device where a full planetary gear is in between half geared sun and half geared ring gears. Notice also that the gear almost makes half revolution when it engaged to the sun gear and almost two revolution when it engaged to the ring gear. I do not know what would be the application of this system be, but it is an interesting concept.
