斜盘式柱塞泵柱塞-缸体摩擦副的润滑计算与分析

The lubrication calculation and analysis for the piston and cylinder tribopairs in slanting axial piston pump

通过对柱塞-缸体间的油膜厚度进行理论计算与分析,进一步分析柱塞-缸体间的倾角、供给压力、柱塞自转及偏心距等相关因素对油膜压力分布的影响,并从润滑角度提出改善其润滑状态、减少磨损和延长使用寿命的建议。

Calculates and analysis the lubricating oil film thickness between the piston and cylinder, and a further study on the influence of parameters like obliquity angle between the piston and cylinder, providing pressure, piston＇s self-rotational velocity, eccentricity on the oil film pressure distribution, And from the lubrication angle advances some suggestions for improving lubrication state,reducing wear and prolonging the useful life longevity.
