Bearing supporting a swashplate of a hydraulic axial cylinder machine

Abstract

A sliding swivel link is kinematically connected to an arcuate bearing cage in a hydraulic axial cylinder machine (of the kind having a concave cylindrical bearing face in the machine casing, a corresponding convex cylindrical bearing face on the swashplate, and an arcuate bearing cage with rolling contact bearing elements contained within the cage and disposed in the space between the concave and convex bearing cases) for positively displacing the bearing cage to a theoretically correct position on each change of tilt of the swashplate. The sliding swivel link includes a flexurally elastic rod which is pivotally connected at one end to the swashplate and which is pivotally connected at its other end to the casing. The rod is longitudinally slidable within the pivotal connection to the swashplate and is also linked to the bearing cage so that the bearing cage is always urged into a position on the line connecting the two pivotal connections at the opposite ends of the rod.
