Abstract
The present invention is a self-aligned continuously variable transmission between an input shaft having a first axis of rotation and an output shaft having a second axis of rotation which is parallel to the first axis of rotation. The CVT comprises a first set of cones tapered in a first direction and a second set of cones tapered in a second direction opposite to the first direction. Each cone of the first and second sets of cones has an axis of rotation oriented such that a portion of a surface thereof is parallel to a portion of the surface of each of the other cones in the same set. A power transfer ring tractionally engages the first and second sets of cones on the parallel portions thereof to transfer power from said first set of cones to the second set of cones. The power transfer ring is movable axially of said first and second sets of cones along the parallel portions to vary the speed ratio from the first set of cones to the second set of cones. The input shaft is in operative driving engagement with the first set of cones to cause rotation of the first set of cones when the input shaft rotates. The second set of cones is in operative driving engagement with the output s…
