To make bearings easy to use and durable, we need to start from many aspects, including selecting suitable bearings, correct installation and disassembly, proper lubrication and maintenance, and reasonable use conditions. The following are some specific measures and suggestions:
1. Select suitable bearings
Clear use conditions:
Analyze the function, structure, use position of bearings, load (size, direction), rotation speed, vibration impact, bearing temperature (ambient temperature, temperature rise) and surrounding atmosphere (corrosiveness, cleanliness, lubricity) of the mechanical device.
Select suitable bearing types according to the use conditions, such as deep groove ball bearings, angular contact ball bearings, cylindrical roller bearings, tapered roller bearings, etc., to meet different load-bearing capacity and rotation accuracy requirements.
Select bearing configuration:
Usually, the shaft is supported by two bearings in the radial and axial directions, one side is used as a fixed side bearing, bearing radial and axial loads, and the other side is used as a free side bearing, bearing only radial loads and can move axially.
Select a suitable bearing configuration, such as the structural selection of fixed and free end bearings, to ensure the stability of the shaft and the life of the bearing.
2. Correct installation and removal
Choose appropriate installation tools:
Use appropriate tools such as wrenches, screwdrivers, pliers, etc. to improve installation efficiency and avoid damage to the bearing.
Pay attention to the installation order:
Generally speaking, install the outer ring first, then the inner ring, and finally the retainer. Ensure the correct installation order to avoid bearing wear or damage.
Cleaning and inspection:
Before installation, clean the bearing surface and check for impurities or damage.
During installation, ensure that the bearing fits properly with the shaft or bearing seat to avoid overtightening or loosening.
Follow the manufacturer's instructions:
Follow the manufacturer's installation and removal instructions to ensure correct operation.
3. Proper lubrication and maintenance
Choose appropriate lubricants:
Choose appropriate lubricants such as oil or grease according to the bearing type and working environment.
For high-precision, high-speed bearings, it is recommended to use special grease or add lubricants.
Regularly change lubricants:
Regularly check the lubrication effect and change the lubricant according to the usage time and mileage.
Avoid using too much or too little lubricant to avoid overheating or insufficient lubrication of the bearing.
Regular cleaning and inspection:
Clean the bearing and its surrounding area regularly to ensure that there is no residue or debris.
Check the appearance, wear degree, rotation flexibility, etc. of the bearing to detect and deal with problems in time.
4. Reasonable use conditions
Control load:
Ensure that the equipment operates within the rated load range and avoid overloading.
If the equipment load changes, the bearing should be adjusted to adapt to these changes.
Control temperature:
Check the bearing temperature regularly to ensure that it is within the normal range.
For high temperature environments or heavy load applications, consider using special materials and installation methods to reduce the temperature.
Prevent shock and vibration:
Avoid exposing the bearing to shock or vibration to prevent bearing damage or loosening.
For applications susceptible to shock, consider using buffer bearings or other shockproof designs.
5. Regular maintenance and replacement
Preventive maintenance:
Perform preventive maintenance on bearing types that are prone to failure.
Regularly replace easily worn bearing parts such as balls or cages.
Replace in time:
If the bearing is severely damaged or cannot meet the use requirements, it should be replaced with a new bearing in time.
Select the appropriate model and grade when replacing, and replace it in the correct way.
By choosing suitable bearings, correct installation and disassembly, proper lubrication and maintenance, and reasonable use conditions, bearings can be made more useful and durable.
