What issues should be noted during the use of square hole agricultural machinery bearings

During the use of square hole agricultural machinery bearings, the following key issues need to be noted:

1、 Lubrication management

Adding lubricating oil: Lubricating oil plays a crucial role in protecting bearings. Before use, the equipment should be refilled according to the manufacturer's manual and ensure the use of clean lubricating oil. At the same time, it is necessary to avoid excessive mixing and filling of grease to avoid affecting the performance and service life of bearings.

Choosing the right lubricant: Choosing the right lubricant is crucial for reducing vibration noise, friction, and wear. Suitable lubricants should be selected and added on time according to the working conditions and instructions of the bearings.

2、 Maintenance and Repair

Regular inspection and cleaning: Regular cleaning and inspection of bearings, timely detection and replacement of worn parts, can extend the service life of bearings. The inspection includes checking the clearance, noise, vibration, and whether there are cracks, fatigue peeling, and other phenomena of the bearings.

Avoid over tight fit: Over tight fit may lead to premature bearing failure. During installation, it should be ensured that the clearance between the bearing and the journal is within the specified range.

3、 Operation and Installation

Correct installation: The correct installation of bearings has a significant impact on their performance and lifespan. Special tools should be used for installation to avoid damaging the bearings during the installation process. At the same time, it is necessary to ensure that the installation position and radial clearance of the bearings meet the requirements.

Smooth operation: When starting and stopping the equipment, it should be operated smoothly to avoid sudden impact loads causing damage to the bearings.

4、 Operation monitoring

Monitoring vibration and noise: The vibration and noise generated by bearings during operation are important indicators reflecting their operating status. These data should be regularly monitored and recorded to promptly identify and address potential issues.

Pay attention to high-temperature operation: When bearings operate in high-temperature environments, attention should be paid to their lubrication and friction issues. Insufficient lubrication can lead to increased wear and temperature rise, while excessive lubrication may generate excessive heat, causing chemical deterioration of the lubricating oil.

5、 Regular replacement

Develop a replacement plan: Based on the frequency of equipment use, working conditions, and the material and performance of bearings, develop a reasonable replacement plan. Timely replace aging and damaged bearings to ensure the continuous and stable operation of the equipment.

Avoid long-term overload operation: Prolonged exposure to loads beyond the design range or excessively fast speeds can accelerate bearing wear and damage. Therefore, this situation should be avoided during use.

In summary, it is necessary to pay attention to lubrication management, maintenance and repair, operation and installation, operation monitoring, and regular replacement of square hole agricultural machinery bearings during use. Only by following the correct methods of operation and maintenance can the normal operation and extended service life of bearings be ensured.
