| 摘 要： | 对轴向柱塞泵滑靴副稳态工况下动压承载规律展开了理论和试验研究，考虑了滑靴所受离心力等倾覆力矩的影响，结合了滑靴实际受力情况，建立了稳态工况下滑靴副摩擦动力学模型，研究了滑靴底面油膜动压承载规律.结果表明，滑靴与斜盘之间总是形成楔形收敛间隙，有利于滑靴副动压油膜的形成，滑靴倾斜方位角基本稳定在170°左右.试验结果较好地验证了仿真结果.

| Abstract: | The hydrodynamic bearing ability of slipper/swash plate pair in axial piston pumps was studied under steady state.Considering the effect of centrifugal on the slipper tilt and analyzing the other forces on the slipper,a tribo-dynamic model of slipper/swash plate pair under steady condition was developed to study the law of hydrodynamic lubrication of oil film between the interfaces.The result shows that the gap between friction pair is always convergent wedged-shape and the tilting azimuth angle of slipper is around 170 degrees basically.This micro motion of slipper is helpful for the hydrodynamic lubrication film.The simulation result was testified well by the experiment. |

| Keywords: | slipper/swash plate pair hydrodynamic lubrication tilting azimuth angle |
