The slewing bearing is a component that needs to be used in many mechanical equipment. It is a large bearing that can withstand comprehensive loads. In addition, it can withstand large axial and radial loads and overturning moments at the same time. It is also more common. In the case of common use, the fault problem is more obvious, such as fracture or abnormal noise during use. The following slewing bearing manufacturers mainly talk to you about why slewing bearings appear abnormal sound.
When this kind of abnormal noise occurs, it should be clear first that when the slewing bearing is idling just after leaving the factory, there will be a uniform sound of steel ball rolling, which is a normal sound; It usually disappears after a period of rotation and running-in. What we are talking about today is a relatively loud and special noise. When you hear a special noise, you need to pay attention. So what is this abnormal noise? Learn more below!
1. Uneven bolts on the mounting surface are loose
When abnormal noise occurs, it needs to be due to the problem of installation operation. When the unevenness of the installation surface does not meet the requirements, it will cause the raceway to form a negative clearance, resulting in abnormal noise; in addition, when the pinion is poorly meshed, Abnormal noises may also occur, which may also cause broken teeth; in addition, when the mounting bolts are loose, the slewing bearing will be elastically deformed, and a negative gap will be generated at the deformed position. It is necessary to check immediately and tighten the bolts as required.
2. There is a foreign body in the slewing bearing
When there are foreign objects such as sand particles and iron filings inside the slewing bearing, non-periodic vibration will occur, and at the same time, there will be a failure of inflexible rotation. When this happens, it is necessary to strictly clean the bearings, shafts, seat holes and matching parts before installation, and remove foreign objects in the lubricant in time; remember to avoid using plastic cages with impure materials or embedded foreign objects. This will remove the corresponding abnormal noise.
