Abstract
A planetary gear transmission having the capability of accepting input power from two separate, counter-rotating shafts, and combining the input power with application to a single output shaft. The two input shafts are coaxial and each is coupled to its own input sun gear. The output shaft extends from the side of the transmission opposite to the input shafts and is coaxial therewith. Various series of planetary gears mounted on a planet carrier provide the coupling between the input and output sun gears. There is no ring gear, and the carrier is not independently driven. The planetary gear transmission is combined with a continuously variable transmission and a direct drive coupled in split power paths from a single drive shaft to provide constant speed output over a range of 2:1 variation in speed of the drive shaft.
