摘要 |
The invention relates to a swashplate pivot bearing (10) in an adjustment unit of a hydraulic axial piston machine (1) with a timing/tracking mechanism (20) for the cage (14) of a roller bearing arrangement (11). The timing/tracking mechanism (20) is in this case distributed to the two end regions (16, 17, 18) of the roller bearing arrangement (11) in such a way that one part is active only during the pivoting of the swashplate (7) in one direction and the other part is active only during pivoting in the other direction. The timing/tracking mechanism (20) is preferably designed in the manner of a slotted-link control with guide tracks (24, 25, 26) and with a guide element (27, 28). |

1. A swashplate pivot bearing (10) of an adjustment unit of an axial piston machine (1), in which a swashplate (7) is mounted in a roller bearing arrangement (11) which has an inner segment (12), an outer segment (13) and a cage (14) for guiding a plurality of rollers (15), the rollers (15) being arranged between the inner segment (12) and the outer segment (13),
the inner segment (12), outer segment (13) and cage (14) being designed in each case as a circle segment, the inner segment (12) being connected to the swashplate (7), the outer segment (13) being arranged on a housing (2) of the axial piston machine (1), and a timing/tracking mechanism (20) being provided, which controls the movement of the cage (14) with the effect of limited tracking of the movement of the swashplate (7), characterized in that a first and a second timing/tracking mechanism (20) are formed at each end region of the roller bearing arrangement (11), and the first timing/tracking mechanism (20) only takes effect during the pivoting of the swashplate in one direction and the second timing/tracking mechanism (20) only takes effect during the pivoting of the swashplate (7) in the other direction. |
