Abstract
A drive system securable to a base for connecting a pair of generally parallel drive shafts to a single output shaft has a rigid nondeformable housing supported on the base by primary supports lying in a plane perpendicular to the rotation axes of pinion and drive gears rotatably carried in this housing. Each of the pinion gears is connected through a flexible coupling to one of the drive shafts and the drive gear is connected to the output shaft. The supports are deformable so that stresses which normally misalign the pinion and drive gears are compensated for outside of the housing by these supports and the drive gears remain in perfect alignment. The output shaft may extend completely through the housing and be journaled in front of the housing in a fixed bearing, and the primary supports lying in the symmetry plane of the housing may be gudgeons received in journals and permitting tipping of the housing.
