How to prevent bearing failure due to clearance changes?
When selecting bearings, consider their type, size, material, and precision grade to ensure they meet the equipment's operating requirements and load conditions. Also, pay attention to the bearing's clearance and fit requirements, avoiding overly tight or overly loose fits.
When installing and removing bearings, follow the correct procedures and use appropriate tools and methods to avoid damage or deformation. During installation, ensure that the bearing's clearance meets the design requirements, avoiding excessive or undersized interference.
During operation, bearings should always be kept clean and dry to prevent contaminants such as dust, impurities, and moisture from entering the bearing interior. To this end, dust and water-resistant measures such as protective covers and seals can be implemented.
Bearing lubrication is critical to maintaining proper operating condition. Select the appropriate lubricant and lubrication method based on the bearing type and operating environment, and change the lubricant regularly to ensure adequate lubrication. Additionally, regularly check the bearing's operating conditions, such as temperature and noise, to promptly detect and address any abnormalities.
During equipment operation, avoid subjecting bearings to excessive loads and impact. Bearing loads and impacts can be reduced by optimizing equipment structure, improving transmission methods, and adjusting operating parameters.
Regular inspection and replacement: Bearings, as vulnerable parts of equipment, should be inspected and replaced regularly. Regular inspections can promptly detect bearing wear, clearance changes, and other issues, allowing appropriate measures to be taken. When bearing wear reaches a certain level, it should be promptly replaced with a new one to ensure the normal operation of the equipment.
Preventing bearing clearance failure requires a multi-faceted approach, including selecting appropriate bearings, proper installation and removal, maintaining cleanliness and dryness, regular lubrication and maintenance, avoiding overload and impact, and regular inspection and replacement. Only by comprehensively considering these factors can bearing clearance failure be effectively prevented.
