Patent abstract
In one version of this invention, a gear box has mounting means such as a pair of facing walls for mounting the bearings for the axles carrying the gears. Each mounting means supports its bearing with a different stiffness to compensate for different loads imposed by gears that are closer to one of the bearings supporting the axle than the other. The different stiffness of each bearing mounting equalizes load-induced shifts of the position of the bearings holding the axle. Such a mounting equalizes such shifts, allowing the axles to remain substantially parallel and the gears in alignment. Aligned gears better maintain line contact between individual gear teeth, thereby reducing wear and breakage of the teeth.
