驱动轴防尘套破损的失效案例分析

Case analysis of damaged dust cover of drive shaft

汽车驱动轴防尘套破损是常见的故障类型,防尘套的材料一般性是橡胶或者橡塑材质,它的破损原因有很多种可能性。对于案例中的该故障件,我们采取外观检测、断口分析和材料检测等方法进行分析,排除防尘套材料问题等因素,确定破损产生的根本原因。该案例中破损的根本原因是受外物划伤所导致,进一步分析和探讨可能存在导致这种破损的环境和过程,提出一些改善措施以减少该类风险产生。

Damage to the dust cover of the drive shaft of an automobile is a common failure type.The material of the dust cover is generally rubber or rubber plastic.There are many possible reasons for its damage.For the faulty parts in the case,we adopt methods such as appearance inspection,fracture analysis and material inspection to analyze,eliminate factors such as dust cover material problems,and determine the root cause of the damage.The root cause of the damage in this case was scratches by foreign objects.We will further analyze and discuss the environment and process leading to this damage,and propose some improvement measures to reduce this type of risk.The root cause of the damage in this case was scratches by foreign objects.We will further analyze and discuss the environment and process leading to this damage,and propose some improvement measures to reduce this type of risk.
