According to different structural types, Fenghe slewing bearings can be divided into four-point contact ball slewing bearings, double-row angular contact thrust ball slewing bearings, crossed cylindrical roller slewing bearings, crossed tapered roller slewing bearings, and three-row cylindrical roller combined slewing bearings. The above-mentioned various types of bearings are divided into different structures such as gearless external gear or internal gear according to whether they have teeth and the distribution of gear teeth.
Due to the different working conditions of slewing bearings, most of them work under eccentric load. In addition to bearing axial load and radial load, the bearing must also overcome the effect of overturning moment. Therefore, the bearing selection calculation is based on the load-moment diagram. The curve is the method commonly used by major manufacturers at present as the selection method of slewing bearings
After the slewing bearing is installed, the appropriate amount of grease should be filled and the slewing bearing should be filled to make the grease evenly distributed. The slewing bearing will inevitably lose part of the grease after working for a period of time. -Lubrication should be added once after 100 hours. For slewing bearings that work in high-temperature environments or dusty conditions, the cycle should be appropriately short. When the machine is shut down for a long time, it must be filled with sufficient grease.
