Abstract
A speed adjusting mechanism for roller traction toroidal continuously variable transmission is disclosed, which comprises an input disk; an output disk coaxially and symmetrically positioned relative to the input disk; a rotation shaft thought the axis of input disk and output disk; a screw rod coaxially connected to the rotation shaft and being rotated accordingly; and a plurality of friction balls respectively contact with the input disk and output disk and rotate same; each friction ball respectively revolved on its own center axis and each center axis respectively connected to a supporting bracket and each supporting bracket respectively connected to an arc-shaped screw gear; wherein the screw rod is engaged to the screw gears so that they will rotate correspondingly to let each center axis tilt to the same extent so that the input disk and out disk will have different rotation rate.
