Abstract (en)
[origin: EP0903433A2] An improved belt transmission between a driving pulley and a driven pulley comprises a floating pulley (6) with a pair of identical circular winding surfaces (8,9) between which there is a third circular winding surface (7) which has a different diameter from that of the pair of surfaces and which is coaxial therewith, a pair of identical belts (10,11) coupling the floating pulley (6) kinematically to one of the driving and driven pulleys by being wound around the pair of identical surfaces (8,9) of the floating pulley (6) and around one of the driving and driven pulleys, and a third belt (5) coupling the floating pulley (6) kinematically to the other of the driving (12) and driven pulleys by being wound around the third surface of the floating pulley and around the other of the driving and driven pulleys. The floating pulley or even one or other of the driving and driven pulleys may be of the type with a diameter which is variable according to the speed of rotation. <IMAGE>
