Our Prototype Ratcheting CVT

[Nately27]

as an excerpt from the gearbox thread:

here is what i think wouldbe light, simple, cvt for a bike

A couple of us here, miket and others, have been working on a ratcheting CVT. Our first fully functional prototype was finished last week. It has a gear ratio from 1 to 3, and should have a completely uniform output (although we havent hooked up a DAQ system yet).

I would suggest turning down the volume, a bunch of guys start yellin halfway through... the input is not constant, so its tough to see the speed increase, especially from that angle.

Its still overweight and oversized for a bicycle, but at this stage it should handle 120[ft-lbs]. So we're still happy with it.

Hey - looks pretty cool.

Just remember - don't show off too much if you have some P.A.F. stuff in the works for the near future...

Try right-click "Save target as" and then play it.
Wouldn't stream for me, but worked that way.

its an avi file, so should play in quicktime or winamp, I'm gonna try to get another video up today, with some pics too.

I was wondering if you have the ratcheting CVT video posted somewhere that I can access without authorization?

[Sonic Reducer]

+1, says authorization required.
what are your future plans for the project?
