Abstract
A torque transmitting gearing system of the nutating type is equipped with a nutating idler member which is in torque transmiting engagement with both a stator and an output gear. Torque transmission between the respective elements is achieved via respective series of rolling, torque transmitting elements in the form of tapered rollers. The rollers are maintained in substantially continuous contact with both their respective driving and driven raceway surfaces, which are formed with trochoidal curvature. Within a given pair of coacting gear surfaces, one surface will be formed with epitrochoidal curvature, and the other with hypotrochoidal curvature.
