Analysis and Optimization Design About Oil Leakage of Engine Crankshaft Front Seal

针对某搭载整车冬季适应性试验的发动机曲轴前油封渗油问题,进行产品设计、产品质量、生产装配等多方面的分析,最终确认曲轴前油封渗油的原因与装配工装及油封安装孔粗糙度有关。

For the oil leakage problem of the engine crankshaft fi＇ont seal in the vehicle winter adaptability test, though the analysis on many aspects such as product design, product quality, production assembly, and so on. Finallyit is confirmed that the reason of oil leakage of front seal with assembly tooling is related to oil seal installation hole roughness.
