Abstract
A variator suitable for an automotive continuously variable transmission utilizes a roller frictionally engaging two rotating plates. The plates are connected to an input such that they rotate at the same speed but in opposite directions. To change the ratio, the roller is moved along an axis perpendicular to the axis of rotation of the two counter-rotating plates. Power from the roller is transmitted to a bevel gear which meshes with an output bevel gear. The output bevel gear rotated about the same axis as the plates.
