Patent ID: 7793582

Claim:
Swash plate pivot bearing for a hydraulic axial piston machine of variable throughput volume, comprising roller-bearing segments, which are held in arcuate cages, are arranged between a hollow-cylindrical bearing surface for a swash plate in a housing and a cylindrical bearing surface on the swash plate cage control elements are provided, which prevent the cage holding the roller bodies from slipping out of a predetermined position in the pivot bearing, the cage control elements are integrated in the roller-bearing segments by at least one cylindrical roller body engaging with the hollow-cylindrical bearing surface and the cylindrical bearing surface with a positive engagement, the hollow-cylindrical bearing surface and the cylindrical bearing surface are each formed by a bearing shell inserted in the housing and on the swash plate, the bearing shells are constructed as parts formed without cutting and have two sets of counter teeth spaced apart from each other in an axial direction, the bearing shells are each provided on at least one axial end with a rim oriented in a radial direction, and the counter teeth are arranged on the rims.
