Abstract
A continuously variable transmission may have a first set of rollers and a second set of rollers that act upon skewed driving and driven surfaces of discs. The input to output ratio of the continuously variable transmission may be changed by pushing either one of the first and second sets of rollers closer to a rotating shaft. To maintain symmetrical loading within the continuously variable transmission, an idler disc assembly may have a strain compensator that deflects to compensate for deflection of outer discs due to elasticity of the main shaft.
