CV (Constant Velocity) Joints

Hi!

Does anyone know of a company that sells small scale constant velocity joints? I.E ones that arent quite as big as car ones, but are big enough and strong enough to cope with torque generated at a shoulder joint?

All Hobby grade RC cars have CV joints. Walk into any hobby shop you will have tons of options.
Better yet vist towerhobbies...

I tried "CV drive shaft" as search term. Try other terms.

Brijesh,

thanks for that, but Im looking for something meatier than R/C car CV's. I have Bosch GPA's for each shoulder rotation DOF (but linear actuators for the shoulder swivel) so the CV's need to be able to handle a fair amount of torque. Something inbetween R/C car cv's and small car Cv's. This is why my searches havent thrown anything up yet because I suspect that they'll be rare if not custom builds.

 :(

maybe go kart cv's. sry don't know where to get them

edwardking:
Ahhh...I thought that Go-Karts didnt use CV joints, but those mini dune buggy things do and they're definately smaller than most car ones. I'll try to find out who makes them and see if they will do.

Thanks for the idea!
