ABSTRACT:
A variable speed drive consisting of a control gear train made up of a central gear which is eccentrically adjustable, an intermeshing walking gear and an overrunning gear form a speed control gear train with the gears connected together by a linkage which includes a hinge connection between the gears. The speed control gear train develops an output speed for the overrunning gear which is a direct function of the degree of the eccentricity of the central gear. The overrunning gear is operatively connected through a second gear train to an output. By controlling the eccentric position of the central gear it is possible, while the gears are running, to control the output speed by simply regulating the eccentric position of the nonrotatable central gear of the speed control gear train. While the gear train is fully operating, the speed control is movable and carrier plate positioned without in any way interfering with gear operation so that the speed of the output shaft is continuously adjustable while the shaft continuously operates. Thus, there is available a complete range of control movement so that the output shaft is movable from static condition through micrometric amounts to full speed and back again while the input shaft can be at any speed and torque.
