The mechanism of a pencil sharpener with stationary annulus and rotating planet carrier as input. Planet gears are extended into cylindrical cutters, rotating around the pencil that is placed on the sun axis. The axes of planetary gears join at the pencil sharpening angle.


Just love this stuff.....
