No. The second one is neat though. If you got a spacer that matched the curve of the sprockets you could get something pretty low friction and low slop
@Ethan5956F Maybe not your design, but a couple of these (with a 1/2" shaft connecting them) could do a 90 degree power transfer pretty effectively. (negligible power loss, negligible slop as far as I can tell)
The vex u joints have a non constant velocity transfer iirc. You’d be better off doing something like a Hobsons joint. Here’s a demonstration of a prototype I made a while back:
There’s also a vid I posted at some point floating around in vtow where Im spinning it with my hands. Can’t find it tho
(Note im not currently using any Hobson joints for any 90° transfer, as it’s inferior to most bevel designs because it relies on sliding friction rather than rolling resistance. However, the slop can be made quite low, and the friction is very smooth compared to most other models I’ve seen. If it’s tuned and supported correctly it works better than the crown gears contraptions I’ve seen so far. As I said before though, this is not the best design. There are better options. Pls don’t use a hobsons joint in vrc)
There are ways to get around the friction but yes there is essentially no way to get around them being canti’d so you have to use really strong and really short rods if you want them to support any load (main reason why I wouldn’t recommend them in vrc)
I messed around with making that type of joint thang shows too and I gotta say it’s pretty difficult to get anything worth the time working out of that in vrc. Itd be easy to make one of those in vexu with 3D printing but there’s no point cuz u can just make or buy a bevel lol
cnc’ing the metal pinions into custom bevel gears could be viable, but it requires some pretty heavy machinery, and not something most teams could easily do.
