 | | Need Help: Rotating Sections of a Spaceship —Leonard Hoffman
| | | | Heya guys, Right now I'm planning on building a large "science factual" spaceship with a rotating centrifugal-gravity hab-ring. (URL) Drawing> I was wondering if anyone could give me some hints/suggestions/how-to for powering the rotating section. (...)

| | | | | | (...) Most probably - assuming the rings are both balanced all you need to overcome is friction. And they won't be spinning all that fast. (...) Yes you can - you can connect as many motors you like in parallel. Their output shafts can be connected (...) (20 years ago, 24-Nov-04, to lugnet.build, lugnet.technic, lugnet.space, FTX)

| | | | | | | (...) I just figured how to do the different directions on a single (URL) (forgive the MSPaint drawing). And speed is actually something I don't want - the HabRing has to be very slow since I'm going to have detail I want people to see inside of it. (...)

| | | | | | | | (...) Cool! But don't knock yourself out trying to get it to run off a single motor - unless you only have one!! You'd probably find on the real craft, they would be driven independently, with computer synchronisation. (...) LOL don't worry it (...)

| | | | | | | (...) The key thing is keep the center of gravity of the ring at the drive axle. If it is 1mm off then you will need a lot more torque, and the rotation speed will be non-uniform. (...) You can just use 3 bevel gears or this piece (URL) to do (...) (20 years ago, 24-Nov-04, to lugnet.build, lugnet.technic, lugnet.space)

| | | | | | In lugnet.build, Leonard Hoffman asked: (...) 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 (...) (20 years ago, 24-Nov-04, to lugnet.build, lugnet.technic, lugnet.space, FTX)

| | | | | | | (...) 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 (...)

| | | | | (...) Hey Lenny, I just wanted to pipe in with my two cents. I've been working on a ship with a rotating mid-section, though it's probably not as large as yours is looking, it's a medium minifig scale ship, and it only has one rotating section, in (...)
