摘要:

某公司正常生产过程中风机内轴承断裂,通过现场取样,对轴承、滚子、滚柱、支撑架部位进行化学成分分析、硬度检验测试、金相检验等一系列理化性能试验,初步确定轴承失效的原因。通过对损坏部件及未损坏部件进行实验分析,实验及分析数据对比后得出,保持架和滚子在制造过程中存在加工缺陷、组织分布不均匀、热处理不当等因素,导致运转过程中发生断裂。

Abstract:

During the normal production of a company, the bearing of fan was broken, and a series of physical and chemical performance tests, such as chemical composition analysis, hardness test and metallographic examination, were carried out on the bearing, roller, pin roller and support frame by field sampling to preliminarily determine the causes of bearing failure. Through the experimental analysis of damaged parts and undamaged parts and the comparison of experimental and analytical data, it is concluded that the machining defects, uneven distribution of microstructure and improper heat treatment of the cage and roller in manufacture result in the bearing fracture during operation.

Key words:  fan, bearing fracture, physical and chemical performance test, cause analysis
