ABSTRACT:
A gear system for driving a pair of rotary loads, such as a pair of helicopter rotors operating in ambient air, with a single rotary input comprises a planetary gear train, the sun gear of which is driven by the rotary input, and the planetary gear carrier and annulus gear of which respectively drive the loads via output shafts coupled thereto by suitable first and second coupling means, respectively. Where rotary outputs of substantially equal torque are desired, as where the rotors are of like dimension, one of the output couplings further comprises speed-reduction gearing and/or means for driving an auxiliary unit with the second output. An idler gear is further employed where the rotors are to rotate in opposite directions.
