Description
Illegal Gear Triangle features three gears meshing in a triangle. As most people know, gears are not supposed to be put in a triangle, as they would then lock up. The issue was discussed by Numberphile, showing some Henry Segerman three-gear examples that do turn together, albeit not in a plane. The gears feature in the Illegal Gear Triangle are herringbone gears with threefold rotation symmetry. All three gears turn in the same clockwise direction, gear A driving gear B, B driving C, and C driving again A.
