  • Variable speed rotary power transmission
    Patent number: 4409862
    Abstract: A variable speed rotary power transmission comprises a planetary gear train having a cage with at least one planet gear meshed between a ring gear and a sun gear for orbital motion about an axis common to the ring gear and the sun gear. A driven output is connected to one of the planetary gear train elements and a driving input rotatably drives another of the planetary gear train elements. A variable speed drive assembly varies the relative rotational speed of the remaining planetary gear train element such that the driven output is rotatably driven at a speed which is continuously variable throughout a predetermined speed range without varying the speed of the driving input. In one preferred embodiment, the driving input is connected to the cage and the variable speed drive assembly rotatably drives the ring gear in the same rotational direction as the cage.
