A flexible Chain
grabcad
A small piece of study. The assembly behaves like a real chain exept that one ring won't turn within two other. I Updated the lenght for 20 rings. A bit slower to rebuild 40 path mate :)I tried to make a new assembly with two of this assembly but is slow several second to rebuilt and it may also fail.I added the mating pulley. The shape took me some time, but it's just to develop on a polygon which the segment is the sum of one ring encumbrance and its internal pitch. For this chain model is precisely 6.75 + 3.
