针对机油泵在试生产中遇到的卡死现象进行分析.利用有限元分析软件Ansys,结合实际经验,采用了一种更全面的分析方法,得到机油泵在极限实验状态下的相关分析数值,找出造成卡死的主要因素为从动轴和从动齿轮的尺寸公差设计不合理.根据此原因,采取相应的方法进行设计改进,并通过实验对改进方案进行验证,最终证明了分析结论的合理性.
The sticking phenomenon of a kind of oil pump,encountered in its pre-production,was analyzed.By using the finite element analysis software Ansys combined with practical experiences,a more comprehensive and reasonable analysis method was proposed.The oil pump was analyzed under extreme experimental conditions.It is found that the main factor causing the oil pump's sticking is the unreasonable dimension tolerances of the driven shaft and one of the driven gears.According to that appropriate measures were adopted for design improvement.The improvement scheme was validated through experiments,and the rationality of the analysis was finally proved.
