Hydrostatic axial piston machine for use as swashplate machine or bent axis machine, has wing segments of support bar with chamfered edges, where wing segments are distributed non-uniformly in circumferential direction

摘要

The hydrostatic axial piston machine (1) has a cylinder drum (4) rotatably arranged in a housing (9) around a rotational axis (2), which is provided with a piston recess (5). The piston recess is alternately in connection with the control terminals (21) on a control surface (11) during the drum rotation. The wing segments (31) of a support bar with the chamfered edges are distributed non-uniformly in the circumferential direction. A hydrodynamic relief force (F-e) of an axial sliding bearing is arranged at a distance from the rotational axis by the arrangement of the wing segments.
