Shandong Dezhou slewing bearing. 3.. 'Slewing bearing' plays a very important role in large-scale mechanical work, so we must pay attention to maintaining it when using it at work, and always pay attention to whether it is used during production. If there are some abnormalities, they need to be repaired as soon as possible to extend the life.
' Most customers have misunderstandings when it comes to slewing bearing maintenance. They believe that the lubricating oil of the slewing bearing and the lubrication cycle of the big and small arms are the same, and they should be applied every day. In fact, this approach is wrong. If the lubrication cycle is too short, there will be too much lubricating oil in the bearing, which will break the dust ring and leak out. When there is leakage, impurities will also enter the inside of the bearing, thereby damaging the normal operation of the bearing. Generally, the lubrication interval of slewing bearings is about every hour. The lubrication period can be adjusted appropriately according to the intensity of work. Applying it once a week is most suitable.
' The extreme pressure lithium-based grease applied to the slewing bearing when it leaves the factory must be refilled with new grease according to different working conditions when it is used. The raceways of the slewing bearing must be filled with grease regularly. Generally, Ball bearings should be refueled once every hour of operation, and roller bearings should be refueled once an hour. In special circumstances, such as tropical areas with high humidity, dust, and large temperature differences, the lubrication cycle must be shortened during continuous operation. New grease must also be added before and after the machine stops running for a long time. Each time lubrication must be performed, the raceway must be filled with grease. Fill the grease until it oozes out from the sealing belt. When filling the grease, slowly rotate the slewing bearing to make the grease evenly filled. The tooth surface should be cleaned of debris frequently. You can choose to add lubrication according to your own situation. Grease, during the first transfer hour, the pre-tightening force of the bolts should be checked in time, and every subsequent hour of rotation should be checked to ensure sufficient pre-tightening force. It is prohibited to only flush the slewing bearing with water to prevent water from entering the raceway and avoid hard objects. Enter the tooth meshing area and check the seal integrity regularly. If it is found to have fallen off, it should be reset in time.
' Because the slewing bearing cannot stop operating in mechanical equipment at all times, the wear and tear is serious. Therefore, we must learn to maintain it when using it, and learn to take notes when repairing problems, so that we can prepare for rainy days and improve overall work efficiency. 3, :-- -Mr. Ding
