Maintenance and repair
Maintenance, repair, and troubleshooting
To maintain the original performance of rolling bearings and ensure long-term use in good condition, it is necessary to regularly inspect and maintain the bearings to prevent malfunctions, ensure reliable operation, and improve efficiency and benefits.
Regular maintenance should be carried out according to the operating conditions and standards of the machinery. The content includes monitoring the operating status, supplementing or replacing lubricants, and conducting regular disassembly inspections.
The maintenance items during operation include bearing rotation noise, vibration, temperature, lubricant status, and so on.
Identify abnormal conditions during operation, investigate the cause, and take corresponding measures. Carefully inspect the disassembled bearings as needed.
Bearing abnormality detector
Predicting abnormal conditions of bearings during operation is extremely important in production. Bearing abnormality detector can monitor the condition of bearings during operation. Once an abnormal condition occurs, it will immediately sound an alarm or automatically shut down. It can prevent faults and achieve scientific maintenance.
Damage and Countermeasures of Bearings
Generally speaking, proper use of bearings can achieve fatigue life. But if unexpected early damage occurs, it cannot be used again. Unlike fatigue life, this early damage is referred to as failure or accident. This is often due to inadequate consideration of installation, use, and lubrication, foreign objects invading from the outside, or insufficient research on the shaft and bearing seat.
The damage status of bearings, such as scratches on the ring and flange of roller bearings, may be caused by insufficient lubricant, inappropriate grade, defective oil supply and discharge structure, foreign object intrusion, bearing installation errors or excessive shaft deflection, or a combination of the above reasons.
Therefore, it is difficult to determine the true cause of bearing damage solely through investigation. However, if we fully understand the machines, working conditions, and peripheral structures that use bearings, clarify the situation before and after the failure occurs, and analyze the damage to the bearings and various related reasons, we can prevent similar failures from happening again. Representative causes and countermeasures of bearing damage were provided.
