摘要： An external gear type hydraulic pump or motor wherein the trunnions of gears in the chamber of the housing are surrounded by annular bearing members. The peripheral surface of each bearing member defines with the adjacent internal surface of the housing an arcuate gap whose width increases in a direction toward the respective end face of the corresponding gear. To this end, portions of or the entire peripheral surfaces of bearing members and/or portions of or the entire internal surfaces of the housing have a conical or spherical shape. The gaps are located in the low-pressure zone and reduce the likelihood of wear upon those end faces of bearing members which are adjacent to the end faces of the gears because the bearing members can tilt in response to increasing load without localized rubbing against the gears. Additional gaps can be provided between the end faces of the gears and the adjacent end faces of the bearing members to further reduce the likelihood of uneven wear upon the bearing members.

摘要： A hydraulic gear machine which may be utilized as a pump or motor has a housing forming a cavity in which a pair of gears having meshing teeth is mounted for rotation. Sealing elements are interposed between the axial ends of the gears and the bearings mounting the gears for rotation; these sealing elements have first surfaces which face the gears and second surfaces facing the bearings and being formed with recesses which form fluid-pressure spaces. At least one seal member is provided adjacent the respective second surfaces and serves to delimit the respective recess. Each seal member has one sealing face which engages an inner circumferential wall of the housing and another sealing face which engages an outer surface of one of the associated sealing element and bearing, which outer surface extends circumferentially of the axis of rotation of the gears.

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 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： An arrangement for centering an end wall of a housing of a hydraulic gear machine, such as a pump or a motor, with respect to the open end of an internal chamber provided in a housing body forming the circumferential wall of the housing includes a plurality of pins which are received in a press-fitting manner in bores of the end wall and protrude beyond an end face of the end wall which faces and closes the open end of the chamber in the mounting position. The pins may have contact surfaces which are turned to the same diameter as the corresponding inner surface of the housing body which bounds the open end of the chamber, or they may exactly fit into the open end, or overlap slightly with the inner surface in which event some material displacement or deformation takes place during the assembly of the end wall with the housing body. The bores in the end wall may be equiangularly distributed along a circle centered on an axis coinciding with that of an opening for a drive shaft in the end wall and, in the mounting position, with that of a circular section of the inner surface at the open end. A cylindrical projection may be provided at the other end face of the end wall for clamping the end wall in a clamping arrangement of a material-removing machine during the material-removing operation for producing the contact surfaces of the pins.

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： An external gear pump wherein the gears are installed in an eight-shaped compartment of a central housing section which is flanked by two covers. The outlet port of the housing communicates with two arcuate recesses for metallic inserts which are biased against the adjacent gears by fluid pressure in the outlet port whereby the inserts urge the gears against those portions of the internal surface of the central housing section which are located opposite the recesses. Such portions of the internal surface are formed with narrow first cutouts which communicate with the outlet port. The internal surface is further formed with relatively wide additional cutouts which are located between the first cutouts and the recesses and communicate with the inlet port. The force which is produced by fluid in the cutouts opposes the force which urges the gears against the internal surface of the central housing section to thus reduce the force with which the stubs of the gear shafts are urged against the housing.
