  • Variable speed friction transmission
    Patent number: 5407399
    Abstract: A variable ratio friction transmission is described in which one element is a straight sided cone and the other a roller or wheel. The two are in frictional engagement. The roller or wheel moves over an element of the cone to change the speed ratio, and at all times stays parallel to itself and moves along a straight line axis. This axis passes through the apex of the cone at all times, but the cone is tilted about its apex to contact the roller or wheel as the ratio is changed.
