Abstract
A torque sharing drive and process for sharing torque accommodates tooth inaccuracies on the rack and outer pinions. A driving pinion mates with first and second gears. The driving pinion is radially, bidirectionally, movable in response to gear separation forces only along the line between the centers of the driving pinion, the first gear and the second gear. First and second outer pinions are rotatable with the first and second gears, and as the driving pinion moves radially toward the first or second gear in response to gear separation forces, the first or second gear is angularly and rotationally advanced with respect to the other gear accommodating inaccuracies in the teeth of the rack and outer pinions. Alternatively, when gear separation forces are balanced, the driving pinion resides approximately equidistantly intermediate the first and second gear and the first and second outer pinions are approximately in phase.
