Briefly on the structure classification and characteristics of slewing bearings

2019-09-26

Slewing bearings, also known as slewing bearings, are large-scale special-structure bearings that can simultaneously accept large axial loads, radial loads, and overturning moments. Usually, it has equipment holes, smooth oil holes and sealing equipment, which can meet the different needs of various hosts under various working conditions. The slewing bearing itself has the characteristics of compact structure, convenient guidance and rotation, simple equipment and easy protection.

Structural classification of slewing bearings

The commonly used structural methods of slewing bearings are single-row, double-row four-point contact ball slewing bearings, double-row angular contact thrust ball slewing bearings, interspersed cylindrical rollers and interspersed tapered roller slewing bearings, three-row cylindrical roller slewing bearings, balls Different structural methods such as column hybrid slewing bearing. The above-mentioned various types of bearings are divided into different structures such as non-tooth type, external tooth type, and internal tooth type according to whether they have teeth and the scattered parts of the gears.

Bearing characteristics of slewing bearings

The slewing bearing can be separated according to different structural characteristics to meet the needs of the working host under various load conditions. Among them, the four-point contact ball slewing bearing has a higher dynamic load capacity. The carrying capacity of the double-row reducing ball turntable is much better than that of the single-row ball turntable. Interspersed cylindrical roller turntable has high static load capability. The ball-column combined slewing bearing has a greater ability to receive axial and radial loads and overturning moments under the condition of ensuring a certain degree of rotation accuracy.
