摘要
燃油泵滑动轴承的浮动特性直接影响燃油泵的容积效率,针对现有某型号用燃油泵滑动轴承在浮动过程中存在的偏磨现象,通过卸荷槽、引油孔、负载压力、滑动轴承内孔等对滑动轴承浮动特性的影响进行理论及多维度批量仿真分析。结果表明,卸荷槽及滑动轴承内孔直径在不同配置条件下对滑动轴承的浮动特性影响较小;引油孔的位置位于节圆附近较为合适,且半径在0.6~1.2 mm之间,数据可为进一步优化燃油泵的性能做理论参考。
The floating characteristic of the sliding bearing of the fuel pump directly affects the volumetric efficiency of the fuel pump.Theoretical analysis and multi-dimensional batch simulation analysis of the influence of unloading grooves,oil guide holes,load pressure,sliding bearing inner holes,etc.on the floating characteristics of sliding bearings,aiming at the eccentric wear of the sliding bearing of a certain type of fuel pump during the floating process.The results show that the unloading groove and the bore diameter of the sliding bearing have little effect on the floating characteristics of the sliding bearing under different configuration conditions.The location of the oil introduction hole is more appropriate near the pitch circle,and the radius is between 0.6~1.2 mm.The data can be used as a theoretical reference for further optimizing the performance of the fuel pump.
