Abstract
A differential drive system includes a housing having a pair of opposed apertures aligned along a longitudinal axis of the housing. First and second output shafts are positioned in respective apertures and are each at least substantially aligned with the longitudinal axis. First and second spur gears are secured to the first and second output shafts, respectively, positioned proximate respective inboard ends thereof. An output gear is within the housing and has a central bore substantially aligned with the longitudinal axis. First and second planetary spur gears are mounted on the output gear to rotate therewith and to rotate with respect to the output gear about respective planetary axes offset from and substantially parallel to the longitudinal axis of the housing. The first and second planetary spur gears are respectively drivingly engaged with the first and second spur gears to transfer torque to the first and second output shafts.
