摘　　要：N8160柴油机在使用过程中,曾出现严重的传动齿轮表面点蚀现象,着重从齿轮强度和轴系扭振两方面分析了可能的原因,并提出了实际改进措施。改进后的新机组在一段时间的耐久考验过程中,各方面性能指标达到了设计要求,这证明采取的措施是富有成效的。When used for some time, there are severe pitting corrosions on the surface of the transmission gears of N8160 diesels. In this article, some analysis and researches of this phenomenon are introduced, from the aspect of gear intensity and torsional vibration. And some amendment proposals that are put into effect are provided. After a period of endurance test, the performance of the improved machines have met the design criteria, which has proved that the amendments are of great effect.
