Abstract
A gear transmission employing at least one pair of non-circular gears to form the intermeshing pitch curves so that one non-circular gear can be given the periodically variable number of rotations on the basis of the exponentially functional increasing mode or the same decreasing mode with respect to the rotational speed of the other non-circular gear, thereby obtaining a gear type continuously variable transmission.
