Hydrostatic gear machine, preferably gear pump, the drive shaft of which is arranged in axially and radially loadable rolling bearings and, via a coupling, has a torque connection to a drive bar present in the attachment bearing. The object and aim of the invention consist in the continuous lubrication of the attachment bearing, including coupling, in the low-pressure range, to guarantee long life and low conveying flow losses. According to the invention, this aim is achieved by the low-pressure side of the gear machine having, via an axial recess of the bearing body and an adjoining duct in the cover of the attachment bearing, a liquid connection to the interior of this cover, which receives rolling bearings and sleeve for bearing the drive bar and/or for torque transmission from the latter to the drive shaft. Furthermore, via a recess of the cover in the passage region of the drive shaft and via the bearing gap of the same in the bearing body, the lubricating circuit with the low-pressure side is closed. The area of application of the invention is hydrostatic gear machines with an attachment bearing, which can be used as a pump or an engine. <IMAGE>
