Analysis of Oil Film Morphology of Valve Plate Pair in Axial Piston Pump

In this paper, we delve into the oil film morphology of the valve plate pair in the axial piston pump. Specifically, we introduce the Euler method for multi-coordinate transformation and establish the oil film morphology equation when the cylinder is inclined and eccentric relative to the valve plate. Meanwhile, it is necessary to point out that the oil film morphology equation can also reflect the position of the valve plate relative to the cylinder. In order to verify the proposed oil film morphology equation, we carry out simulation verification. The simulation results show that the oil film morphology equation can well describe the oil film shape of the valve plate pair. The study of the oil film morphology equation can lay a foundation for the subsequent study of the lubrication and friction characteristics of the valve plate pair.
