      How to Judge the Abnormal Work of Slewing Support

      Slewing bearings are lubricated with grease, and abnormal noise may be caused by lubrication problems. Common reasons are lack of grease in raceway, uneven grease filling, poor aging of lubricating grease, wrong selection of lubricants, etc. In order to solve this problem, only the use of appropriate lubricants, timely filling, timely replacement can solve the problem. Below with the small knitting to understand how to determine whether the slewing bearing is working properly.
      When abnormal noise occurs in the rotating support, check whether it is due to the problem of installation operation. When the unevenness of the installation surface does not meet the requirements, it will cause negative clearance of the raceway, which will produce abnormal noise. In addition, when the pinion gear is not meshed properly, it may also produce abnormal noise, which will also cause the fault of broken teeth. When the installation bolt is loose, it will cause the elastic deformation of the slewing bearing and negative clearance in the deformation position, so it is necessary to check immediately to tighten the bolt according to the requirements.
        When there are foreign bodies such as sand and iron chips in the inner part of the slewing support, non-periodic vibration will occur, and there will also be a malfunction of inflexible rotation. When this happens, the bearings, axles, seat holes and matching parts should be cleaned strictly before installation, and foreign bodies in lubricants should be removed in time. It is important to avoid using plastic cages with impure materials or foreign bodies embedded in them so as to remove the corresponding abnormal noise.
        Generally, after starting the slewing bearing, we can judge whether the rolling sound belongs to the normal operation state by judging the rolling sound. If abnormal sound occurs, then we need to check which link is damaged. If the cause of the failure is found, then the follow-up needs to be done. Corresponding and effective maintenance methods should be adopted to carry out maintenance and solve problems.
        The above is about how to judge the work of slewing support is abnormal content introduction, hope to increase your understanding of slewing support, and to some extent help you use slewing support!
