Title: Analysis and Prevention Measures for Failures of
Abstract: roller bearings with conical rolling elements have a wide range of applications in the metallurgy industry, but due to harsh working environments, they are prone to failure. This paper analyzes the failures of roller bearings in the metallurgy industry and proposes corresponding prevention measures. It aims to provide some reference significance for the application of roller bearings in the metallurgy industry.
1. Failure Analysis
The failure forms of roller bearings in the metallurgy industry mainly include contact fatigue failure and abrasive wear. In contact fatigue failure, the roller bearings and the inner and outer rolling elements are subject to alternating contact stress in high-speed movement, which leads to metal fatigue phenomenon on the working surface, and ultimately causes failure. In abrasive wear, the roller bearings are subjected to high-pressure alternating load and stress under the periodic high and low load and contact, and as a result, the bearings fail due to the poor surface geometry of the bearings and the components.
2. Prevention Measures
(1) Material and Processing Quality
Using high-quality materials with high strength, high wear resistance, and high corrosion resistance is the main material of roller bearings, and advanced processing techniques such as precision machining can effectively improve the service life and wear resistance of bearings.
(2) Lubrication and Sealing
Proper lubrication and sealing are essential to keep roller bearings in good working conditions, and can effectively reduce the wear and friction of bearings.
(3) Assembly Sizing and Surface Quality
The accuracy and precision of the bearing installation, as well as the smoothness of the relevant components, are crucial to reducing the risk of failure.
(4) Environmental Conditions
The repetitive impact loads, shocks, and large temperature changes can cause stress concentration and wear of bearings. Therefore, it is necessary to reduce such effects.
(5) Regular Inspection and Maintenance
Regular inspection and maintenance of roller bearings can effectively extend their service life. Regular cleaning and lubrication of bearings and bearings vehicles, as well as precise assembly and good surface quality, can also effectively reduce the risk of failure.
Conclusion: The failure analysis and prevention measures of roller bearings in the metallurgy industry are crucial. By selecting high-quality materials, advanced processing techniques, proper lubrication and sealing, accurate assembly and smooth surface quality, avoiding adverse effects of installation and use environments, and regular inspection and maintenance, roller bearings can effectively reduce the risk of failure and extend their service life in the metallurgy industry.
