Abstract
A shaft is coupled to a circumjacent gear substantially midway between the bearings at each side of the gear. This substantially equalizes the vertical loading on the gear bearings--eliminating the tilt or cant in the gear which would otherwise result, and minimizing abnormal tooth wear in the gearing system. An example of the present invention is a long driving shaft such as the drive shaft of a propeller in a large ship.
