Chebyshev couple N=2
■ Chebyshev wheel couple element version.
This is an extended version of Chebyshev N=2 Polygon Wheel.
Rough/ About-Line symmetry form was given by one coordinator bar added.
---- I've found by heuristic learning. from analogy of Chebyshev N=2 Polygon Wheel.
---- From this solution, its implementation becomes very easy.
Tip:
Symmetry is not exact, axis angle 0° and 360° (and 180°) case are just the same as exact symmetry.
In other angle case is rough indeed. It's enough for real life using.
Cross bar VV' is shares with Axis A ▲, It is dependent to the CC' and DH, its angle is fixed uniquely.
1st 360° Pedal C ● cycle, black couple is on the ground. ---- It looks C is rotated, V is fixed.
2nd 360° cycle, black couple is off the ground. But system is driven by Pedal C always.
---- From total point of view, It looks C is fixed, V is rotated . (From inner relative view is C is rotated always, and V is fixed.) This is so odd/ interesting.
