浅谈变速器输出油封漏油故障分析及改进措施

The fault analysis and improvement measures of the output oil seal leakage of transmission are discussed

介绍变速器输出油封使用时漏油故障,通过对油封、装配、使用维护的调查分析,确定失效原因,制定改进方案,并将改进方案应用在实际生产中,跟踪售后数据,改进效果显著,故根据匹配车型、使用工况,合理选择油封,并严格控制、提升油封装配过程控制是降低油封故障的关键。

The article mainly introduces the faults of the output oil seal leakage of transmission. The failure causes of the output oil seal are confirmed by investigating and analyzing the oil seal, assembly and maintenance. Then an improvement scheme is proposed and applied in the actual production, and the after-sales data are followed up, the remarkable improvement effect will be confirmed. Therefore, choosing the right oil seal, strictly controlling and improving assembly process of the oil seal are the key to reducing the thilure of the oil seal according to matching the models and operating conditions.
