PUB - Model test for the experimental investigation of the wear behaviour of the sliding shoe - swash plate contact
In axial piston pumps, hydrostatically partially balanced contacts are predominantly used. The use of these pumps in variable-speed configurations, such as in electro-hydrostatic axes, has proven to be very challenging in terms of robustness. Particularly affected here is the slipper-swashplate contact, via which the piston loads are supported. The wear processes and driving effects occurring here have not yet been sufficiently addressed in the current state of research.

Within the scope of this publication, a model experiment is therefore to be presented which allows the targeted investigation of the wear behaviour of the slipper-swashplate contact under controlled and reproducible conditions. The objectives of the model experiment are, on the one hand, the empirical investigation of the interactions in variable-speed operation and, on the other hand, the validation of simulative considerations.
