Abstract
The present invention comprises a harmonic drive transmission for the simultaneous production of a first and a second rotary output. The invention includes a primary housing, a first flexspline may be hermetically secured within the housing with a first wave generator arranged therewithin. A second flexspline may be hermetically secured to the first flexspline within the housing, the second flexspline having a second wave generator arranged therewithin. A first driveshaft is connected to the second wave generator, and a second driveshaft is connected to the first wave generator. A first circular spline is in engagement with a plurality of gear teeth and connected to a first output shaft, and a second circular shaft is in engagement with a plurality of gear teeth and is connected to a second output shaft, to provide simultaneous output by a plurality of output shafts from a hermetically arranged harmonic drive transmission.
