How to judge whether the slewing ring is working normally

The slewing ring is lubricated with grease, and the abnormal noise may be caused by lubrication problems. Common causes include lack of grease in the raceway, uneven grease filling, poor grease quality, aging, wrong lubricant selection, etc. To solve this problem, we only need to use appropriate lubricant, fill in time and replace in time. Let's follow Xuzhou Wanda slewing ring to learn how to judge whether the slewing ring is working normally.


When the slewing ring makes abnormal noise, first check whether it is due to the installation operation. When the unevenness of the installation surface fails to meet the requirements, a raceway will be formed to form a negative gap, resulting in abnormal noise; In addition, when the pinion meshing is not good, it may also produce abnormal noise, which will lead to the fault of broken teeth; In addition, when the mounting bolts are loose, resulting in elastic deformation of the slewing ring and negative gap in the deformation direction, it is necessary to check immediately and tighten the bolts as required.


When there are sand particles, iron filings and other foreign matters inside the slewing ring, it will produce aperiodic oscillation and inflexible rotation. In this case, the bearing, shaft, seat hole and matching parts shall be strictly cleaned before installation, and the foreign matters in the lubricant shall be removed in time; Remember to prevent the use of plastic cages with impure materials or embedded foreign matters, so as to remove the corresponding abnormal noise. Generally, after starting the slewing ring, we can judge whether it belongs to the normal operation state by judging the rolling sound. If there is an abnormal sound, we need to check which link is damaged. If the cause of the fault is found, we need to adopt corresponding useful repair methods for maintenance, solve the problem.
