once tensioned the chosen angle is fixed in place.
This could look a bit like such:
– hull segments walls form a positive cylinder segment on one side with trapezoid teeth
– hull segments walls form a negative cylinder segment on one side with trapezoid teeth
The axis of the cylinder being normal to the axes of the hull segments.
Somewhat like an elbow hinge. There is a virtual center of rotation though. And this shall not move unlike a hinge.
A bit like a circle segments of …
– a normal outside toothed gear and
– an exact same size matching inside gear.
(But no need for actual involute profile here.)
(wiki-TODO: Add a sketch making this description much more clear.)
The ReChain CoreChain need some sideways leeway to be able to
properly tension the joint for all angles that are possible to pick.
A natural strategy to choose is picking a highly divisible number of teeth
to get a good deal of options for choosable angles.
Size of interdigitating teeth depends on …
– the limits of detail due to manufacturing methos (macroscale) or atomistic nature of matter (nanoscale)
– load resilience constraints
– avoiding undercuts of the self centering teeth that'd make assembly impossible
(wiki-TODO: Add a few example numbers of what angles can be chosen given a well picked design.)
Alternative approach
One could perhaps alternatively use an approach with hirth joints,
but this requires a redirection of the ReChain core chain tehsion by 90°.
