Alas, the Technic toolkit has nothing in the way of planetary gears, or a means to do coaxial shafts. But if you’re willing to do brick-modding, you could carve out the center of a 48-tooth gear (so it can free-spin, but roughly); then pin it to a beam (to provide a smooth edge) and thread the pair onto an axle, which would be fixed to the ship’s nonrotating section. You could then drive the 48-tooth with a spur gear (or several) run parallel to the spin-shaft. (This is speculation.)

I’ve considered the same problem now and then, with regards to SF replicas: an (unfinished) “2001’s” Discovery and an (unstarted) “Babylon 5” Omega-class Destroyer. And Joe Meno wants to see some visually distinctive original designs for microscale spaceships, so a similar problem applies; but with less weight.

The Discovery’s centrifuge can’t have an axle down the center -- the transfer shaft is there. I was considering an arrangement of tires (bearing stand-ins) rolling in a race built of 1x5x4 arches and inverted arches.

(...) There are a couple of option without resorting to mods: (URL) Use a large technic turntable. This is probably preferable, as the ring will be large and it will give you a better mechanical advantage, and allow a much more sturdy connection (...)
