ABSTRACT:
A ball-jointed bearing arrangement of the piston heads in an axial piston machine within a drive flange wherein a bearing member formed of a material with good antifriction properties for receiving a piston head is seated in a recess of the drive flange whereby all bearing members are covered by a covering plate which is detachably fastened to the drive flange. The bearing member is formed of a spherically indented cup of a flat material, such as sheet metal, which is inserted into the respective recess, which recesses conform in shape, pitch circle and distribution to the piston heads, however, are constructed in conformance with the thickness of the respective spherical dished cup deeper and larger in diameter, and in which the covering plate is traversed by the piston heads and is fastened on the side of the drive flange towards the piston heads.
