Great site on all types of CVTs and thier applications.

This is what I was trying to emulate on a smaller scale and with one cone. I couldnt find the supplies (chain) to actually do it the way the anderson is setup but I will try to find a way to do it like it. The site you posted was awsome.
-Thanks

If you use oposing cones, you can use standard v-belt. the only problem is your limited to a certain range of ratios due to the width of the belt, and the travel of the cones.

Although it is hard to see because the tranmission is moving, there are counterweights on the nearest pulley that are meant to push the two halves together. The counterwieghts are similar to those found inside a governor and the force they apply to the pulley varies according to the rpm of the shaft.

494 had the weights on one end, but they also had a torque converter on the other end.

The way they explained it to me was that the counterweights changed the ratio based on RPMs and the torque converter would change it based on load.

Sounds interesting.

Sitting here thinking I realized the importance of the second cone and if I put that if I sync the belt and the cones just right, I could actually put 4 ribs on the cones this way it could be a "toothed" belt going between the two cones.
This would be ideal for spinning.

Thanks for all the help. I'll post more drawings as I finish.

Okay I have revised my design and will be posting hte pics. Could I get some feedback on this design?

-Thanks
