i used 3D Studio Max R3.1 (very out of date, current version is 9 or 10)
It's one of three designs I'm looking at.
The upside of this design is that it can be disengaged completely.
The downside of this design is that it never reaches an overdrive gear at the transmission level. in fact, it never even reaches a 1:1.
I like the Anderson CVT design (
http://www.andersoncvt.com website currently down) but the flexible teeth on the cone gears look unreliable to me.
I would like to make a CVT where the main transference is done using a motorcycle chain, but I'm not having any luck on finding a way to do it.
Later on I'll animate 1 or 2 other designs i have in mind and see how that flows with the feedback.
Odref.com isn't bringing up a reference.
I saw the pulley gear on HowStuffWorks.com but a steel belt in high temperature resistant rubber just sounds like it would wear out too easy and be difficult to replace.
