摘要
Abstract
Aiming at the frequent fracture failure of the guide roller spindle in the belt winder arm of one fin-ishing mill unit,the root cause of the spindle fracture was identified through on-site investigation,fracture anal-ysis,structural verification and design rationality validation.The stress concentration caused by the design of the bearing inner ring circlip groove led to fatigue fracture under cyclic load.Based on the failure analysis results,an improvement scheme was proposed to cancel the unnecessary circlip groove and optimize the spindle head struc-ture.The effectiveness of the improvement scheme was verified by strength simulation and on-site application test.After improvement,the service life of the spindle was extended from 6-8 months to more than 24 months,the unit downtime was reduced by 95%.This improvement idea can provide reference for the structural optimiza-tion of similar cold rolling finishing equipment.关键词
