Ceramic Parts for Hydrostatic Pumps and Motors


This paper deals with the development of ceramic parts in hydrostatic machinery as the result of a research project, whose purpose was to demonstrate the potential improvement of ceramics. The properties of ceramics, how to use them in hydrostatic machines, and the differences in the design approach compared to the design of metal parts will be shown. The lack of material data for ceramics was resolved by developing a test method and specimens that reproduced the load and stress conditions of the component parts. Test results with respect to endurance life and change of machine efficiency are also reported. An outlook for work in the future will be given at the end.
