<p>A roller transmission and gearing mechanism with a driving body, roller means and a driven body; the driving body is coupled to the driven body by means of the roller means, the bodies are guided with a single degree of freedom, and define respective roller guide tracks thereon, the tracks contact the roller means and determine the movement of the roller, which contact the roller guide tracks along rolling curves, the roller guide tracks start and terminate at respective pairs of limit surfaces, and the roles of the driving and driven bodies can be interchanged, furthermore the distances between points of the rolling curve on the driving body and on the driven body are different, the rolling means move with pure rolling motion, and for all 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 roller means, and the lengths of the rolling curves of the driving and driven bodies are equal, and before and after the contact points the rolling curves have angularly inclined tangential planes.</p> |
