<p>The step-up gear has movement tracks (103, 113, 119) formed in rotational disks i.e. drive disks (101, 111), for coupling elements (121, 123, 125, 127), respectively, where movement tracks are arranged facing to each other. The coupling elements are arranged between the rotational disks and moved along the movement tracks. A gear ratio or momentary tracks of the coupling element is determined by a movement angle between the movement tracks. One of the movement tracks is formed at a rotational axis (107) of one of the rotational disks in star, oval or orbital shaped. An independent claim is also included for a method for transforming a driving speed of a rotational disk into an output speed of another rotational disk.</p> |
