Double volleyballSlewing bearingThe damage of the retainer is not easy to judge, and the problem is not obvious in time in use. Today, the editor of Tianyue, Jiangsu, talked about the causes of damage to the double-row ball slewing bearing retainer, and conducted a comprehensive analysis.
Reasons for damage of double-row ball slewing bearing retainer:
1. Sensation
When the bearing is in a sensation, the force inside the bearing may cause fatigue cracks in the retainer. Gradually, this crack will rupture the retainer. To prevent this, bearings equipped with special retainers can be used.
2. Speed exceeds design requirements
If the bearing is operated at a speed beyond the holding material can withstand, inertial force will cause the retainer to rupture. There are high-speed bearings [Cross Roller Bearings] manufactured for this occasion.
3. Wear
Improperly smooth or strong foreign objects can wear the bearing retainer. Sliding friction is avoided when rolling bearings are running. However, the sliding touch between the roller and the retainer is usually impossible to eliminate, so if the smoothness is not good, the retainer is the wear part of the first battle. And the retainer is made of soft material, so it wears very quickly. The gradual clearance of the holder will cause the holder to rupture quickly. The same happens when solid particles penetrate the bearing.
4. Foreign body stuck
The broken parts or particles may get stuck between the retainer and the roller. Prevent the tumbling piece from rolling. This can also cause the holder to break. As long as it can prevent large foreign objects from invading the bearing, the retainer can be safe even under heavy loads.
The above is the reason for the damage of the double-row ball slewing bearing retainer. If the above-mentioned situation occurs in the bearing in use, a comprehensive analysis can be carried out according to the fault to find the problem and deal with the bearing problem.
