Abstract : A speed changer comprising a stationary pulley and a powered shaft defining a sun axis. Two adjustable diameter planet pulleys and a pair of power-transmitting belts transmit power to an output sun pulley coaxially aligned with the stationary pulley. An adjustment screw inversely varies the diameters of the two sun pulleys; resultant changes in belt tension produce changes in the diameters of the planet pulleys. (Author)
