[] The damage of the bearing retainer is not very obvious, and it is not easy to judge under normal circumstances. The vibration of the bearing, the speed exceeds the design requirements, wear, foreign matter jam and skew are the main reasons for the damage of the retainer. Analyze and analyze the situation mentioned above:
1, vibration
When the bearing is under vibration, the force inside the bearing may cause fatigue cracks in the retainer. Gradually, this crack will cause the retainer to rupture. To prevent this, bearings with special retainers can be used.
2, the speed exceeds the design requirements
If the bearing is running at a speed beyond the holding material, the inertial force will cause the retainer to rupture. There are high speed bearings manufactured specifically for this type of application.
3, wear and tear
Improper lubrication or hard foreign objects can cause wear on the bearing retainer. Sliding friction is most likely to occur when the rolling bearing is running. However, the sliding contact between the roller and the retainer is usually not eliminated, so if the lubrication is poor, the retainer is the first wear and tear part. Moreover, the retainer is made of a softer material, so the wear is quite fast. Gradually the gap of the retainer will cause the retainer to rupture quickly. The same happens when hard particles penetrate the bearing.
4, foreign matter stuck
Fragmentation of the part or particles may get stuck between the retainer and the roller. Prevents scrolling from rolling. This can also cause the retainer to break. As long as it can prevent large foreign objects from intruding into the bearing, the retainer can be safe even in heavy load.
