Abstract
A method of compensating for load-induced twisting of a gear assembly under load that includes a gear on a gear shaft, bearings on each side of the gear that support the gear shaft and a carrier fastened to a stationary support surface that mounts a proximal one of the bearings near the stationary support surface and mounts a distal one of the bearings away from the stationary support surface. The method includes the steps of determining the twisting deflection of a distal bearing axis of rotation for the distal bearing relative to a proximal bearing axis of rotation for the proximal bearing and offsetting the position of the distal bearing axis of rotation relative to the proximal bearing axis of rotation in the carrier opposite the determined deflection under no gear loading.
