摘要:
The invention relates to an adjustable axial piston machine having a housing (1), a pivot cradle and a bearing shell (2) which is arranged between the housing (1) and the pivot cradle. The bearing shell comprises a bearing section (21) in the shape of an annular section with an inner end (230, 230') and a bearing shell end region (22.1, 22.2) which extends in one plane with an outer end (23, 23'). A bearing surface (40.1, 40.2), the geometry of which corresponds to the bearing section, is provided on the housing (1). Here, an outer supporting force point (23.1, 23.3) at the outer end (23.1', 23.3') and an inner supporting force point (23.2, 23.4) at the inner end (230, 230') lie on a straight line (24.1, 24.2) which extends on the inner supporting force point (23.2, 23.4) tangentially with respect to the bearing section (21). If a force is present in the circumferential direction of the bearing section (21), the inner supporting force point (23.2, 23.4) and the outer supporting force point (23.1, 23.3) are subjected to a supporting force substantially parallel to the straight line (24.1, 24.2).

The invention relates to an adjustable hydrostatic axial piston machine comprising a drum-type cylinder block (3), which is mounted onto a drive shaft or output shaft (1), one end of which is mounted in a bore of the base (6) of a well-shaped housing (4). Said cylinder block is retained so that it cannot rotate and is provided concentrically with cylinder bores running parallel to the central line of the block. Axially displaceable pistons are arranged in the bores, said pistons being supported by spherical heads against an oblique surface or an oblique face of a cradle-shaped body (14), which is pivotally mounted by anti-friction bearings (16) on shaft journals (15) and is provided with a pivoting drive. The inventive axial piston machine is characterised in that the interior of the housing (4) is provided with approximately semi-cylindrical shells on both sides of the drive or output shaft (1), into which the anti-friction bearings (16) are inserted and in which said bearings are retained by bow-shaped retaining elements (18).

A follow up mechanism (10) for maintaining a timed positional relationship between a bearing cage (35,36) of an arcuate roller bearing assembly (24,26) and a swashplate (19) supported by the bearing assembly (24,26) includes a flexural elastic link (41) pivotally connected to the bearing cage (35,36) and having first and second ends (42,43) slidably disposed within a first bore (48,49) in a pump housing (14) and a second bore (51,52) in the swashplate (19), respectively. The bores (48,51;49,52) are in axial alignment with each other when the swashplate (19) is in the equivalent of its centered position thereby allowing blind assembly of the follow up mechanism (10) thereby eliminating the need for an access opening in the side of the pump housing (14) and the associated cover, gasket and bolts.

Die Erfindung betrifft eine hydrostatische Axialkolbenmaschine (1) in Schrägachsenbauweise mit einer um eine Rotationsachse (R t ) drehbar angeordneten Triebwelle (4), die mit einem Triebflansch (3) versehen ist, und einer um eine Rotationsachse (R z ) drehbar angeordneten Zylindertrommel (7), wobei die Zylindertrommel (7) mit mehreren konzentrisch zur Rotationsachse (R z ) der Zylindertrommel (7) angeordneten Kolbenausnehmungen (8) versehen ist, in denen jeweils ein Kolben (10) längsverschiebbar angeordnet ist, wobei die Kolben (10) an dem Triebflansch (3) gelenkig befestigt sind, und wobei zwischen der Triebwelle (4) und der Zylindertrommel (7) ein als Gleichlaufgelenk ausgebildetes Mitnahmegelenk (30) zur drehsynchronen Drehung der Zylindertrommel (7) und der Triebwelle (4) angeordnet ist. Das Mitnahmegelenk (30) und die Zylindertrommel (7) sind mit einer konzentrisch zur Rotationachse (R z ) der Zylindertrommel (7) angeordneten Längsausnehmung (11) versehen, durch die sich die mit dem Triebflansch (3) versehene Triebwelle (4) durch die Zylindertrommel (7) hindurcherstreckt, wobei im Bereich der Triebwelle (4) ein Durchtrieb eines Drehmoments zu einem zylindertrommelseitigen Ende der Axialkolbenmaschine (1) vorgesehen ist.

The invention relates to an axial piston machine (1) having a pivot bearing (13) which is composed of two pivot bearing parts (13b, 13c) and has a pivot axis (13a) for a swash plate (12), having a gap (a) which is rounded and curved in the shape of a circular arc section between the pivot bearing parts (13b, 13c), and having a cage segment (15) arranged in said gap (a), wherein the cage segment (15) is guided by an angular guide element (19). The guide element (19) has a first guide limb (19a) which extends transversely with respect to the gap (a), projects beyond the latter, is mounted by means of a first rotary bearing (21) so as to be rotatable about its first rotational axis (21b) which extends parallel to the pivot axis (13a) and by means of a first longitudinal guide (23) so as to be moveable on the cage segment (15), and is connected in its one end region to a second guide limb (19b) which extends transversely with respect to the pivot plane (E4) of the first guide limb (19a) and which is rotatably connected by means of a second rotary bearing (24a) to the one pivot bearing part (13b). In order to improve the guidance of the cage element (15), the first guide limb (19a) and/or the second guide limb (19b) has or have in each case a transversely aligned molding (25).

The invention relates to an axial piston machine, preferably having a swash-plate construction with a cylinder drum (3) revolving on the drive shaft (10). The rolling bearing (11) of the drive shaft (10) is automatically flushed from the inside (2) of the housing by leakage operating medium. A shaft sealing device (12) is arranged outside the rolling bearing (11) and means (15) for conveying operating medium through the bearing gap of the rolling bearing (1) is provided. A conveyor plate (15) is arranged, for this purpose, adjacent the rolling bearing (11) on the drive shaft (10) of the machine.
