摘要：
In order to solve the overturning and eccentric abrasion of the slipper-swashplate interface in the axial piston pump, a lubrication numerical model and a coupling solver were developed. The causes of the slipper overturning were analyzed. Micro-stepping was introduced to realize the slipper structural optimization design. The impact of different micro-stepping sizes on slipper posture and oil film lubrication was compared. The results demonstrate that micro-stepping is beneficial to the oil film formation to improve the lubrication performance and the impact of micro-stepping depths on the slipper posture and the pressure and thickness distribution of oil film is more obvious than that of its widths. The lubrication numerical model and micro-stepping structure is conducive to realize the optimal design of axial piston pump and prevent the slipper eccentric abrasion to improve the pump service life and reliability. © 2021, Editorial Board of Journal of Huazhong University of Science and Technology.
