Pivot bearing for swash plate type hydraulic axial piston machine, has guide elements guided between control sliding surfaces, where distance between surfaces is reduced to dimension smaller than dimension for accommodation of elements

摘要

The bearing has a circular cage (07) for guiding a roller body (06), and a control sliding surface (08) extending along a hollow cylindrical storage space (03). A control sliding surface (09) extends along a storage space i.e. center (04). Two guide elements (11, 12) for controlling the cage, are spaced at a distance to each other in the running direction. The elements are connected with the cage and guided between the surfaces. A distance between the surfaces is reduced in a direction of the ends of the surfaces to a dimension, which is smaller than a dimension for accommodation of elements.
