发动机三结合面渗油问题分析与解决方案

Analysis and Optimization Design about Oil Leakage of Engine Three Surfaces

针对某发动机试验缸体、缸盖及正时链罩壳三结合面处渗油问题,进行产品设计、产品质量、生产装配等多方面的分析,最终确认三结合面处渗油的原因与此处振动量大,结合面粗糙度精度高有关。

Aiming to oil leakage of three surfaces among the engine cylinder block, cylinder head, and timing chain cover, by analysis of many aspects such as product design, product quality, production assembly, and so on, finally the reasons of oil leakage at three surfaces are confirmed related to big vibration quantity and surface roughness with high precision.
