Abstract:
In a direct drive transmission:an input drive shaft, an input gear, said input gear mounted on said input drive shaft; an output shaft, an output gear, said output gear being mounted on said output shaft; said input drive shaft and output shaft being mounted, in bearing relation, for rotation in a casing; at least one cooperating pair of intermediate shafts, at least two pinions disposed on each said intermediate shaft, a first one of said pinions being in driving engagement with said input gear, and second one of said pinions being in driving engagement with said output gear; said first pinion being mounted for limited axial movement relative to its said intermediate shaft; said intermediate shafts being coplaner to one another; means for balancing loads between each said cooperating pair of said intermediate shafts, comprising a lever mechanism, said lever mechanism including a lever, said lever being in operative contact with a pair of said first pinions, said lever being mounted for limited rocking movement in the plane of said intermediate shafts such that movement of one of said first pinions towards or away from said lever mechanism causes an equal but opposite application of force on said other said first pinion in the opposite direction to thereby balance loads on said intermediate shafts.
