摘要
Abstract
The fracture of inner ring occurs in the process of bearing installation,the cause of the failure was analyzed by means of macro-examination,fracture analysis,chemical composition analysis,metallographic examination,material and heat treatment quality testing.The results show that the inner ring of the bearing has a partial forging overburn defect,and the bearing breaks along the defect during installation.关键词
