What are the reasons for the shortened service life of slewing bearing?
The slewing bearing is widely used in engineering machinery, and it can also be called a turntable bearing. Speaking of the turntable bearing, I believe that everyone should know. There are many reasons for the shortened life. Today I will tell you what are the reasons for the short life of the slewing bearing.
The reasons for the shortened service life of the slewing bearing
1. Equipment issues
The slewing bearing is knocked directly during installation, and the damage to the bearing with brute force is used. At the same time, the force of the slewing bearing is unevenly used for a long time, causing bearing damage. If the installation is not in place, there will be an error or the bearing position between the gap device between the slewing bearing and the installation foundation during installation, and the bearing gap will be too small. The inner and outer circle is not at the same rotation middle point, forming different intentions.
2. The loading capacity of slewing bearing
Due to the production process and different material used, the slewing bearing has different bearing capacity, the actual operation of the equipment during use exceeds the load capacity, which can easily cause bearing fatigue or collapse, resulting in a serious damage. Damage affects the service life of machinery.
3. Friction
The friction force is a key factor for all machinery. Dust particles, water or other foreign objects enter the tooth co -convergence of the bearings, increasing the friction of the bearings, and wearing raceway and teeth. It will cause damage of slewing bearing and friction caused by friction Dysfunction is the main factor that leads to a decrease in the use time of slewing bearing.
4. Lubrication
Not injecting lubricant or grease oil is not in place; not proper selection of lubricant agents; incorrect lubricating methods or etc. In order to ensure the normal use of the tower machine accessories, when used, you must pay attention to the maintenance of the bearings, apply the lubricant regularly, and do not let the bearings overload for a long time.
