There is a virtual center of rotation though. And this shall not move unlike a hinge. &lt;br&gt;<br /> A bit like a circle segments of …&lt;br&gt;<br /> – a normal outside toothed gear and &lt;br&gt;<br /> – an exact same size matching inside gear. &lt;br&gt; <br /> (But no need for actual involute profile here.) &lt;br&gt;<br /> {{wikitodo|Add a sketch making this description much more clear.}}<br /> <br /> The [[ReChain CoreChain]] need some sideways leeway to be able to &lt;br&gt;<br /> properly tension the joint for all angles that are possible to pick.<br /> <br /> A natural strategy to choose is picking a highly divisible number of teeth &lt;br&gt;<br /> to get a good deal of options for choosable angles. &lt;br&gt;<br /> <br /> Size of interdigitating teeth depends on … &lt;br&gt;<br /> – the limits of detail due to manufacturing methos (macroscale) or atomistic nature of matter (nanoscale) &lt;br&gt;<br /> – load resilience constraints &lt;br&gt;<br /> – avoiding undercuts of the self centering teeth that&#039;d make assembly impossible<br /> <br /> {{wikitodo|Add a few example numbers of what angles can be chosen given a well picked design.}}<br /> <br /> == Alternative approach ==<br /> <br /> One could perhaps alternatively use an approach with [[hirth joint]]s, &lt;br&gt;<br /> but this requires a redirection of the [[ReChain core chain]] tehsion by 90°.<br /> <br /> == Related ==<br /> <br /> * [[ReChain]]<br /> * [[ReChain self centering]]</div>
