摘要： A reversible gear machine which can be used either as a gear pump or as a gear motor regardless of the pressure gradient direction between its inlet and outlet ports includes a housing accommodating meshing gears for rotation about their respective axes which are defined by respective stub shafts extending axially beyond the end faces of the gears. At least one pressure element, which may be constituted by bearing members for the stub shafts, and which is movable axially of the respective stub shafts, has a surface facing away from the gears. A sealing component including a relatively rigid support ring and an elastically yieldable sealing body is accommodated in a groove of the sealing element provided at the aforementioned surface of the latter, such that the support ring contacts the close end wall of the housing and a rib of the sealing body contacts the bottom of the groove and subdivides the latter into two compartments. The sealing component delimits on the aforementioned surface of the sealing element first and second pressure fields which are in communication with the respective ports of the gear machine, and third pressure fields which are situated between the sealing component and the respective stub shafts and which are subjected to the pressure prevailing between the other axial surface of the pressing element inwardly of the root circle of the gear teeth and outwardly of the respective stub shafts. Two of the pressing elements and two of the sealing components may be provided, each at one axial side of the gears.

摘要： A hydraulic gear machine which is particularly suited for use as a reversible hydraulic gear motor includes a pair of gear elements having externally meshing outer peripheral gear portions and stub shafts which are supported in an internal chamber of a housing on respective sleeve-shaped bearings. Two such bearings are arranged at each axial side of the gear elements, one for the stub shaft of each of the gear elements which extends to this axial side. The housing includes a circumferential wall and two end walls. Sealing elements having the configuration of the numeral three are arranged at the interfaces between the bearings and the end walls. The sealing elements are oppositely oriented with respect to a common plane including the axes of rotation of the gear elements at the respective axial sides. Depending on the direction of flow of pressurized hydraulic medium through the machine, a dominating pressure zone builds up at one or the other of the interfaces, the effect of the pressure of the pressurized medium on this pressure zone being to press the bearings in a sealing manner against the gear elements to eliminate gaps therebetween through which the pressurized hydraulic medium could otherwise escape without transferring its energy to the gear elements as useful mechanical energy.

摘要： A housing of the gear motor accommodates a pair of meshing gears which are rotatably mounted in the interior of the housing and which each have a first and a second axial end face. Sealing elements are provided which are located proximal to the respective axial end faces, and an arrangement is provided for forming first fluid-pressure fields which press the sealing elements against the axial end faces. Adjacent at least one of these sealing elements there is provided a space in which an auxiliary fluid pressure field can develop, and an arrangement is provided by means of which the space can be pressurized when it is desired to form therein the auxiliary fluid pressure field so that the same may exert auxiliary pressure upon the associated sealing element to aid in pressing the same against the respective axial end face, and by means of which the space can be vented when such auxiliary pressure is not desired.

摘要： A gear machine, such as a gear pump or gear motor, has a housing in a chamber of which there are journalled two gears which mesh with one another. One of the gears is mounted on a drive shaft the end of which is extended outwardly from the housing. The housing is closed at one side thereof with a cover having a stepped bore for receiving the end portion of the drive shaft. The cover is formed with a circumferential projection concentric with the drive shaft and adapted for centering the cover relative to an external element to be coupled with the gear machine. The stepped bore provided in the cover forms a chamber in which a centering ring with a certain radial play is positioned, which centering ring surrounds the drive shaft. A sealing ring is also positioned in the chamber formed in the stepped bore, which sealing ring sealingly closes the housing. The centering ring provides for reliable aligning of the gear machine to the external element adapted to be coupled with the machine.

摘要： A gear pump wherein the trunnions of two or more mating gears are mounted directly in ring-shaped bearing members or in bearing sleeves which are fitted into the bearing members. The deformation of those surfaces of bearing members which are immediately adjacent to the end faces of the corresponding gears is prevented by enlarging the bores of the bearing members in close proximity to the end faces of the gears, by forming the internal surfaces of the bearing members with circumferentially complete or arcuate grooves, or by reducing the outer diameters of bearing sleeves in immediate proximity to the end faces of the gears. This insures that the deformation of bearing members in response to transmission of forces by the respective trunnions is not propagated all the way to those surfaces of the bearing members which are immediately adjacent to the end faces of the gears.

摘要： An adjustable radial piston machine (pump or motor) is described whose drive mechanism (10) has a comparatively compact structure and an especially good mechanical efficiency. The drive mechanism (10) has a bearing ring (19) which is arranged concentric to a rotor (11) and which can be swung or pivoted about a symmetry axis (Q,H) different from its rotation axis for adjustment of the radial piston machine. An adjusting device (22) for pivoting the bearing ring extends axially parallel to the bearing ring (19) and acts on a facing surface of the bearing ring (19). Working pistons (13) guided in the cylinders in the rotor perform two motion cycles per revolution of the rotor, which are equal, but in opposite directions, over respective 180.degree. angular intervals. Cylinders (12) on opposite sides of the rotor are acted on by identical pressures so that the forces on the rotor are balanced and the rotor rotates largely free of friction.

摘要： A gear machine, such as a gear pump or gear motor, has a housing in a chamber of which there are journalled two gears which mesh with one another. The shafts of the gears are journalled for rotation in bearing sleeves. The housing has an intake for fluid at low pressure and an outlet for fluid at high pressure. The gaps between the teeth of the gears which receive fluid at low pressure communicate with the intake exclusively by way of passages which extend in part along the sleeves and shafts, so that the entire quantity of incoming fluid is compelled to travel in these passages and to cool and lubricate the sleeves and shafts.
