The maintenance and repair of four corner square hole agricultural machinery bearings is an important link to ensure the normal operation of agricultural machinery equipment and extend the service life of bearings. The following are maintenance and repair methods compiled based on relevant reference articles:

1、 Maintenance methods

Keep clean: Before and during use, keep the bearings and their surrounding environment clean to avoid the entry of dust, dirt, and foreign objects.

Regularly clean the area around the bearings to ensure there is no residue or debris.

Use appropriate seals and protective covers to reduce the entry of dust and other particulate matter.

Lubrication management: Select appropriate lubricants based on bearing type and working environment. For agricultural machinery bearings, it is usually necessary to choose lubricating grease with good wear and corrosion resistance.

Regularly replace lubricants, usually based on usage time and mileage. Avoid using too much or too little lubricant to avoid overheating or insufficient lubrication of the bearings.

For high-precision and high-speed bearings, it is recommended to use special lubricating grease or add lubricating oil, and regularly check the lubrication situation.

Regular inspection: Regularly inspect the operation and performance indicators of bearings, including rotational sound, vibration, temperature changes, and lubricant status.

Monitor the changes in bearing clearance, wear, and whether there is any abnormal noise or vibration.

Correct installation: The correct installation method and tools should be used during installation to avoid improper operations such as strong stamping and hammering.

Ensure the correct alignment and fit of the inner and outer rings of the bearing to avoid friction and vibration.

After installation, check if the bearings are securely fixed and ensure that the equipment is in the correct position and angle.

2、 Maintenance methods

Disassembly and cleaning: Remove the bearings from the equipment and record their appearance and residual lubricant content.

Use cleaning agents (such as gasoline or kerosene) to clean the bearings, paying attention to protecting the bearings from direct contact with the dirt in the container, and avoiding damage to the bearing rolling surface during rough cleaning.

After cleaning, dry the bearings with a dry towel and place them in a cool place to air dry.

Inspection and evaluation: Check the condition of the raceway surface, rolling surface, mating surface of the bearing, and the wear of the retainer.

Evaluate the increase in bearing clearance and changes in dimensional accuracy to determine whether the bearing can continue to be used.

Replacement and repair: If the bearing is severely damaged or cannot be repaired, it should be replaced with a new one in a timely manner.

For slightly worn or damaged bearing components (such as balls or cages), repair or replacement of relevant components can be attempted.

Reinstall: Follow the correct installation method and steps to reinstall the bearings.

During the installation process, ensure that all components are correctly installed and tightened in place.

Debugging and testing: After installation is completed, debug and test the equipment to ensure that the bearings run smoothly, without abnormal noise and vibration.

Regularly check the operation status of the equipment and the lubrication of the bearings to ensure that the equipment operates in good working condition.

In summary, the maintenance and repair of four corner square hole agricultural machinery bearings need to comprehensively consider multiple aspects such as cleaning, lubrication, inspection, and installation. Regular maintenance and timely repair can ensure the normal operation of bearings and extend their service life.
