This new gear geometry allows for multiple points of contact arrayed along a curve in space, as compared to standard gears where there is a line of contact arrayed along a surface in space. Immediate benefits are efficiency gains without loss of load capacity , power transfer means within an efficient bearing, long life without lubrication, and an easily 3D printable geometry .
Fracs are the spherical fractal gears used to make fractal gearing mechanisms, They are used to complete mechanisms with proper working arrangements. Either the north and south poles have pivot points which are great for holding. Even numbered fracs can be held point-to-point, and there are not many other ways to hold Fracs, aka Spherigears. Fracs repeat in abundant natural forms all around us, such as blood cells, cactei, ferrofluids, tropical fruits, the coral reefs, space, quantum fields and more. The black frac shown above is even numbered and formed magnetically, so there are no poles.
