  • Patent number: 7793582
    Abstract: A swash plate pivot bearing is provided having roller bearing segments (15) arranged between a hollow cylindrical bearing surface (12) for a swash plate (10) in a housing (3) and a cylindrical bearing surface (11) on the swash plate (10), held in curved cages (17) whereby elements are provided for controlling the cages which prevent the cage (17) accommodating the roller body (16) from slipping out from the optimum position thereof in the pivot bearing. The cage control elements are integrated into the roller bearing segments (15) so that at least one roller body (23, 23.1, 23.2) of cylindrical form has a positive engagement with the hollow cylindrical bearing surface (12) and the cylindrical bearing surface (11). It is thus possible to prevent the escape of roller bearing segments (15) from the bearing gap (22) due to the effects of vibration.
