Abstract
A constant speed drive includes one or more speed summing differentials operably connected to a base shaft and a machine shaft. A primary variator is operably connected to the one or more speed summing differentials to produce a selected constant rotational speed at the machine shaft across a range of engine speeds at the base shaft. An operating range adjustment element is operably connected to the one or more speed summing differentials to adjust a range of engine speeds at which the constant speed drive can output the selected constant rotational speed at the machine shaft.
