Abstract
A method for fabricating a split path transmission system that achieves equal torque splitting between the forward and aft split load paths of each gear train thereof at a predefined operating point by providing an intentional timing difference between gears and pinions of the forward and aft split load paths of each gear train of the split path transmission system is disclosed. The method includes the steps of identifying the torque distribution curves of the forward and aft split load paths of one gear train of the split path transmission system. The method further includes a step of selecting a predefined operating point for the split path transmission system wherein equal torque splitting between the forward and aft split load paths of the one gear train is desired. Next, the forward and aft torque distribution curves are analytically modified as required to pass through the predefined operating point. The interception point with the abscissa of the analytically-modified forward or aft torque distribution curve having the steeper slope is then identified to quantify an input torque range. Finally, the timing relationship of the gears and pinions of the split load path represent…
