<p>A roller transmission and gearing mechanism with a driving body, one or more rollers, and a driven body coupled to the driven body via the rollers. The bodies define at least one pair of respective roller guide tracks thereon. The guide tracks start and terminate at respective pairs of limit surfaces. The rollers contact the guide tracks along rolling curves, and distances between points of the rolling curve on the driving body and the respective rolling curve on the driven body are different such that: for all contacting point-pairs on the rolling curves, the respective tangential planes are parallel to each other; the velocities of the contacting pairs of points are identical but have opposite signs; in the contacting points, the action lines of forces intersect the central axes of the rollers; and the lengths of the rolling curves of the driving and driven bodies are equal.</p> |
