Theoretical and Experimental Research on the Yoke of the Axial Piston Pumps

The paper contains theoretical and experimental researches on the assembly made by the yoke and the inclined disk that equip a swashplate axial piston machine. The theoretical studies concern the stress and deflection state of the assembly due to the carrying pressure of the hydrostatic bearings, made by the slippers and the inclined disk. The simulations were made using the ANSYS program for the experimental state of loads, created especially to be implemented on an experimental test. To validate the finite element models of the assembly, a testing rig has been designed and built. The theoretical and experimental results are in good agreement and furthermore, simulations could be done for the real state of loading.
