As the central axis of the excavator, the turntable bearing is generally not subject to serious failures, such as breakage of the turntable bearing, but even such a small probability of occurrence may occur from time to time during the work of the excavator! In the final analysis, on the one hand, the machine friends neglected the observation and detection of the turntable bearing, and did not pay attention to it when the fault was minor.
What factors should be considered when purchasing turntable bearing?
What are the steps of the correct installation method of the turntable bearing?
How to analyze the common faults of turntable bearing?
1. When purchasing turntable bearings, consider more specific working conditions, axial force, radial force, and overturning moment. Rotate a turntable bearing of suitable size
2. When purchasing turntable bearings, more specific requirements for use accuracy should be considered, and the type of turntable bearing should be selected.
3. Select turntable bearing according to the specific use environment, temperature and other special requirements!
A. the stiffness of the bearing. Standard turntable bearing and zero-backlash turntable bearing have different requirements on the rigidity of the bearing.
B. Positioning. The inner and outer ring raceways of the turntable bearing have a soft belt, which should be placed on both sides of the main load plane. That is, it is 90 degrees staggered from the main load area. There is a jam or "S" mark on the soft strap.
C. Adjust the gear backlash. When installing a toothed slewing ring, it is important to adjust the gear backlash correctly.
When the turntable bearing just leaves the factory, some bearings will make a uniform sound of rolling steel balls when they are idling.
(1) The slight abnormal noise when the bearing is idling will generally disappear after dozens of revolutions. If it does not disappear, it may be caused by the slight deformation of the light bearing of the turntable bearing during transportation, but if the operation is flexible and normal, it can be Rest assured to install and use, it will disappear naturally after a period of use. If the noise is loud or it does not disappear after a period of use (usually 2-4 months), you should contact our company's after-sales service department in time.
(2) If there is abnormal noise in the trial operation after assembly, it should be checked whether the bearing mounting surface is flat and meets the requirements. If the unevenness of the mounting surface does not meet the requirements, it will cause the raceway to form a negative gap and produce abnormal noise. The treatment method is the same as "running after installation". Inflexible"; or the large and small gears are poorly meshed, sometimes tight and sometimes loose, and the meshing is too tight at the large tooth jumping position, resulting in abnormal noise.
After reading this, I believe you have a certain understanding of turntable bearings and have a judgment on whether you need to order turntable bearings.
