摘要
针对天铁热轧带钢生产线的精轧机主传动鼓型齿接轴存在的设计缺陷,对运行中出现的接轴漏油、接轴辊端轴承抱死、接轴轴端给油环抱死、接轴连杆断裂等故障原因进行了分析。经改造,接轴故障率明显降低。同时,将精轧机稀油润滑式接轴改为干油润滑式接轴,其故障率明显降低,满足了精轧阶段轧制的工艺要求,使用效果良好。
Aiming at the design defect of main drive drum gear coupling of finishing mill at Tiantie Hot Rolling Strip Mill, the author analyzes the causes of failures of coupling leakage, bearing seizure at coupling roll end, flinger seizure at coupling shaft end and coupling rod breakage. Modification was executed and coupling fault rate dropped substantially. Meanwhile coupling lubrication was changed from oil type to grease type, which fundamentally solves the critical problem restraining production equipment. The process requirement at finishing phase was met and effect good.
