Abstract

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
