Deep groove ball crack damage of non-standard bearing countermeasures and solutions

Deep groove ball crack damage of non-standard bearing countermeasures and solutions of source: bearing | last updated: - 2020 07 - 13 non-standard bearing fracture characteristics and formation conditions: often occurred in parts and components, raw materials, carbon belt and segregation is serious or not included in the longitudinal extension, from surface to inner crack, crack depth, length of hardenability. Solutions and preventive measures: eliminate carbon belt and organization, not too much impurity of raw material segregation; The rational development of heat treatment parameters, as far as possible factors in the person's action. Characteristics and formation conditions of quenching crack, not often occur in the carburizing and quenching parts or components, and the thickness crack in part on the forefront of the gap. Solutions and preventive measures, the key is to develop a reasonable heat treatment process parameters, in order to improve the operator's skills, try to eliminate the artificial operation factors; Design of the circular arc transition best use, avoid sharp corners. Characteristics and conditions of the formation of quenching cracks, on the surface is easy to produce such grinding crack. Parts of high hardness solutions and preventive measures: tempering heat treatment fully; When grinding feed smaller, reducing grinding heat. Bearing damage: generally, if the proper use of deep groove ball bearings, can be used to achieve fatigue life. But there will be unexpected injury prematurely, not resistant to use. This early damage, and fatigue life, it is called the fault or the quality using the limit of the accident. Much due to the installation, use, do not pay attention on the lubrication, intrusion of foreign bodies from outside, to the shaft, shell heat affected study enough.
