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