Analysis of the causes of abnormal noise in excavator slewing bearings
As an important piece of equipment in construction machinery, the performance of the slewing bearing of the excavator directly affects the operating efficiency and stability of the excavator. During actual use, the excavator slewing bearing sometimes emits Abnormal noise not only affects the work effect, but may also cause damage to the equipment. Below, we will analyze the causes of abnormal noise in the excavator slewing bearing from several aspects.
First of all, installation problems are one of the common causes of abnormal noise in slewing bearings. During the installation process, if the installation is improper or the fastening bolts are loose, the slewing bearing will cause vibration and abnormality during operation. ring. Therefore, the operating procedures should be strictly followed during installation to ensure that all components are installed in place and the bolts are tightened reliably.
Secondly, the intrusion of foreign objects is also a factor causing abnormal noise. During use, if foreign matter such as sand, metal particles, etc. enters the slewing bearing, these foreign matter will cause friction and collision during the operation of the bearing, resulting in abnormal noise. Therefore, regular cleaning and maintenance of slewing bearings is very necessary.
In addition, grease problems are also an important cause of abnormal noise. If insufficient or excessive grease is added, the friction of the slewing bearing will increase during operation. produce abnormal noise. At the same time, if the quality of the grease is not up to standard or has not been replaced for a long time, it will also lead to poor lubrication and abnormal noise. Therefore, when selecting and using grease, attention should be paid to its quality and replacement cycle.
Finally, surface damage is also one of the causes of abnormal noise of the slewing bearing. In the case of long-term use or improper operation, the surface of the slewing bearing may be damaged by wear, cracks, etc. These damages will cause the bearing to produce abnormal noise during operation. Therefore, care should be taken to avoid excessive wear and impact during use, and regular inspection and maintenance should be carried out.
To sum up, there are various reasons for the abnormal noise of the excavator slewing bearing, including installation problems, foreign matter intrusion, grease problems and surface damage, etc. In order to ensure the normal operation and long service life of the excavator, we need to investigate and deal with these problems one by one.
