The slewing ring is lubricated with grease, and the abnormal noise is probably caused by lubrication problems. Common reasons include lack of grease in the raceway, uneven grease filling, poor grease quality and aging, wrong lubricant selection, etc. To solve this problem, you only need to use a suitable lubricant, fill it in time, and replace it in time. Let's follow the editor to understand how to judge whether the slewing ring is working normally.
When the slewing ring has abnormal noise, check whether it is due to the installation operation. When the unevenness of the installation surface does not meet the requirements, a negative gap will be formed in the raceway, resulting in abnormal noise; in addition, when the pinion gear does not mesh well If the installation bolt is loose, the slewing ring will be elastically deformed, and the deformation direction will produce a negative gap. It is necessary to check immediately and tighten the bolts as required.
When there are foreign objects such as sand particles and iron filings inside the slewing bearing, non-periodic oscillations will occur, and at the same time, there will be failures of inflexible rotation. When encountering this situation, it is necessary to strictly clean all the bearings, shafts, seat holes and matching parts before installation to remove foreign objects in the lubricant in time; remember to prevent the use of plastic cages with impure materials or embedded foreign objects. Only by doing so can the corresponding abnormal noise be removed.
Generally, after starting the slewing ring, we can judge the rolling sound, we can judge whether it belongs to the normal operating state, if there is abnormal sound, then we need to check which link is damaged, if If the cause of the failure is found, then you need to adopt corresponding and useful repair methods to repair and solve the problem.
