Abstract
Planet wheels 27 are radially displaceable in orbital motion about a pair of inwardly spring-loaded sun wheels 35, 35' and within an axially adjustable pair of rotationally fixed reaction rings 40, 40', said planet wheels having constant angular-contact with the wheels and rings of both pairs. An axially fixed pivotal reference P between the sun wheels is used for linked connection of the sun wheels, e.g. by the single lever 104, two levers, or toothed members, such that displacement of the respective sun wheels is always equal in magnitude but in opposite axial directions with respect to the axially fixed reference, thus assuring that the instantaneous radius of planet-wheel orbit between the sun wheel and reaction ring on one axial side of the fixed reference will at all times match the corresponding instantaneous radius on the other side. The carrier 25 for the planets 27 is coupled by toothed planetary gearing 28, 41, 46 to an output shaft. <IMAGE>
