Continuously Variable Transmission from the Wolfram Demonstrations Project by Erik Mahieu
This Demonstration models a toroidal continuously variable transmission (CVT). A toroidal CVT is made up of two disks on a central axle and a toroidal roller that transmits motion between them.
The disks are attached to two concave conical surfaces that enclose the torus. One disk (gray) is the input and the other (yellow) is the output. When the roller's axis is perpendicular to the axis of the disks, it contacts them at same-diameter locations and thus gives a 1:1 speed ratio.
You can move the roller up and down, contacting the disks at varying diameters and so changing the speed ratio through the range 1/4 to 4.
