Abstract
A fluid gear pump or motor has a central housing with an end cover on one side and an adapter cover on the other. A pair of gears are rotatable inside the housing and one gear shaft extends through the adapter cover for attachment to another machine. The adapter cover is mechanically grounded to the attached machine. Internal loads on the gear shafts are transmitted to the bearings on either end of the shafts in the two covers. One centering plate transmits the loads from one pair of bearings in the end cover to the housing. Another centering plate transmits the loads from the housing and the other bearings to the grounded adapter cover.
