Abstract:
1. A gearbox, comprising, a plurality of gears forming gearsets, each gearset including at least one shaft extending from the gearset, wherein the gearsets are sized having ratios varying by degrees of separation of a common ratio in a geometric sequence of torques, wherein, the degrees of separation of the common ratio for each pair of shafts is calculated by dividing a total number of gearset combinations of forward speeds in the gearbox by a number of gearsets between a first pair shafts, where the number of gearsets between two shafts is two or more, and then dividing the common ratio from the first pair of shafts by a number of gearsets between the next pair of shafts until all shaft pairs are calculated, and, the geometric sequence for each pair of shafts allows a final gearbox ratio of 1.
