摘要
对大H型钢生产线立辊48t轴承失效的原因进行了分析,通过采取改变轴承游隙、装配方式、改善润滑条件等有效措施,轴承故障率由改造前的18·7%降低到3%,极大提高了轴承使用寿命。
Analysis on failure reasons of 48t vertical roll bearing in large H-beam production line was carried out,through measures such as changing bearing clearance, altering assembly mode and improving the lubricating conditions, failure rate of the bearing was decreased from 18.7% to 3% and work life of the bearing was greatly increased.
