摘要
针对轴向柱塞泵中滑靴副的倾覆和偏磨问题,建立了一种滑靴副润滑数值模型和耦合求解器.在此基础上探究了滑靴产生倾覆的原因,并提出了一种微台阶来改进滑靴结构.通过仿真计算,进一步对比了不同微台阶结构参数对滑靴副姿态和油膜润滑的影响.结果表明:微台阶有助于滑靴副油膜的形成,改善油膜润滑性能;微台阶深度对滑靴微运动姿态、油膜压力和油膜厚度的影响比宽度大;所提出的数值模型和微台阶结构有助于轴向柱塞泵的优化设计,并能有效防止滑靴产生偏磨来提高柱塞泵的可靠性和寿命.
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. Microstepping 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.
