Maintenance and repair of FAG bearings and damage countermeasures
At the time of inspection, it is mainly correct to observe whether the rivet head of the bearing is skewed or loosely welded. The welding of the cage is good or bad. Whether the solder joint is too small, there is a problem that the solder is not strong, or the ball is caused by excessive soldering. They are all special places to pay attention to when testing FAG bearings. There are still some issues to be aware of.
Let's share with you the test of the local part of the bearing in years of work experience. First of all, the inspection of the FAG bearing in the environment should be carried out in a light environment, preferably astigmatism, in order to better observe the outside of the FAG bearing and see that there are no cracks and other abnormalities on the surface. For example, wear, scratches and bumps in the mechanical cloud process can cause the FAG bearing device to shift, resulting in poor position of the device, causing flat load and stress concentration, and reducing the accuracy and service life of the molded FAG bearing.
1. FAG bearing maintenance, overhaul, and abnormal handling
In order to maintain the original performance of the bearing in a good condition for as long as possible, it is necessary to maintain, repair, and prevent accidents, ensure the reliability of operation, and improve productivity and economy. Maintenance is best carried out on a regular basis in accordance with the operating standards for the mechanical operating conditions. The contents include monitoring of operating conditions, replenishment or replacement of lubricants, and inspections for periodic disassembly.
As a maintenance item during operation, there are bearing rotation sound, vibration, temperature, lubricant state, and the like.
2. Damage and countermeasures of FAG bearings
In general, if the bearing is used correctly, it can be used until the fatigue life is reached. However, there will be accidents that are prematurely damaged and are not resistant to use. This early damage, as opposed to fatigue life, limits the quality of what is known as a fault or accident. Many of them are caused by inadvertent installation, use, and lubrication, and foreign objects intruding from the outside are insufficiently studied for the thermal effects of the shaft and the outer casing.
Regarding the damage state of the FAG bearing, for example, the jam of the ferrule of the roller bearing, as a cause, the lubricant is insufficient, unsuitable, the defect of the oil supply structure, the foreign matter intrusion, the bearing installation error, the shaft deflection If the song is too big, there will be coincidences of these reasons.
Therefore, it is difficult to know the true cause of the damage by investigating only FAG bearing damage. However, if you know the mechanical use of the bearing, the conditions of use, the structure around the bearing, and the situation before and after the accident, combined with the damage state of the bearing and several reasons, it can prevent similar accidents from happening again.https://www.supplyforever.com/
