Basically using the ReChain system to not only make
modular quickly recomposable struts for space-frames/space-trusses like RepRec base truss.
But using it to make stacks including bearings, sprockets, and possibly even gears.
Contents
Automated robotic handling
Sprocket stacks can avert the need for the handling of long axles with high aspect ratio.
These may be more difficult to handle automatedly robotically.
Same as with ReChain for mere passive struts.
Self centering
Sprocket stacks can make extensive use of Hirth joints
for the needed self-centering aspect of ReChain.
Pre tensioning
The stack needs to be tensioned hard just like a ReChain strut.
⚠️ But beware. Included bearings need a separate lower clamping force pre-tension.
So far the bearings are pretensionable by tunable axial force.
(Related: ReChain tension redirection principle)
Conical gear-bearings (aka tapered gear bearings)
can be nice as some applied pre-tension can remove backlash basically to zero.
Full cycloid profiles are needed as involute tooth profiles are not meant to be pressed together. <bt>
Or soft atomic teeth at nanoscale somehow maybe …
Positive locking
Same prinnciples as for ReChain struts can be used
