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
