When the slewing bearing just leaves the factory, some bearings will make a uniform sound of steel ball rolling when it is idling, which is normal. When the slewing bearing is running after installation, it will be accompanied by another abnormal and louder sound, which is called abnormal sound.
(1) The slight abnormal sound when the bearing is idling will disappear naturally after dozens of turns. If it does not disappear, it may be caused by the slight deformation of the light bearing of the slewing bearing during transportation. However, if the operation is flexible and normal, it can be installed and used with confidence.
(2) If there are abnormal noises in the test run after assembly, check whether the bearing installation surface is flat and meets the requirements. If the unevenness of the installation surface does not meet the requirements, it will cause the raceway to form a negative gap and produce abnormal noises. The treatment method is the same as "the operation is not flexible after installation";
(3) There are abnormal noises during use (first of all, it should be determined whether it is the sound from the slewing ring bearing. The sound from some steel structures or other components is often mistaken for the sound from the Anhui slewing ring. Therefore, the source of the noise can be determined by stopping the rotation of the slewing ring and the normal operation of other components). , this situation is often accompanied by difficulty in rotation (generally, this situation is likely to occur in an environment with harsh working conditions). At the same time, attention should be paid to whether the sealing strip is damaged; the installation bolts are loose, resulting in elastic deformation of the slewing ring bearing, and negative clearance at the deformation position.
The content about slewing bearings—the causes and solutions of abnormal noise of bearings will be sorted out here for everyone today. If you want to better maintain the bearings of its equipment, exert good performance and prolong its service life, I hope you will develop a good habit of regular maintenance in the future.
