Abstract
The dual output pinion rack drive includes an epicyclic gearbox which permits the division of power of a single motor to first and second spur output pinions which are subjected to slightly different loading conditions based on rack geometry, rack tolerances and gear tolerances. A motor drives an input sun gear which drives planet gears which drive large and small ring gears in opposite rotational directions at similar torque levels while the carrier floats rotationally. None of the gearbox components, the sun gear, the planet gears, the large ring gear, the small ring gear, the planet carrier, and the housing are fixed rotationally. Each ring gear couples to first and second spur output pinions, respectively, and power is transferred through intermediate gear reductions and final planetary gear systems to first and second rack driving output pinions rotating in opposite directions driving the platform up a central rack.
