摘要
某公司125型摩托车大链轮发现大量裂纹,经过对裂纹件进行形貌分析和冶金分析,找到产生裂纹的真正原因,即链轮结构、机加工应力和表面粗糙度等因素的综合作用导致高频淬火裂纹。据此制定了相关的纠正措施,并经初步验证,可满足生产需要。
A large number of cracks were found in big chain wheels of 125 style motorcycle.The actual reasons which resulted in the high-frequency quenching cracks were found by appearance analysis and metallurgy analysis,which are configuration of chain wheel,stresses of machine work,and surface roughness.The correlative rectifying measures are made,and has met the requirements of production by preliminary validated.
