Slewing bearing (slewing bearing), also called slewing bearing, is a kind of large-scale special structure bearing, which can simultaneously accept larger induction loads, such as axial load, radial load and overturning moment. Usually, it has its own installation hole, smooth oil hole and sealed installation, which can meet the different needs of various types of hosts under different working conditions.
The slewing bearing itself has the characteristics of compact structure, convenient guide rail rotation, simple installation and convenient protection. Structural classification of slewing bearings? The structure of slewing bearings is usually used for single-row, double-row four-point touch ball slewing bearings, double-row angular touch thrust ball slewing bearings, interspersed cylindrical rollers and interspersed tapered roller slewing bearings.
Cylindrical roller slewing bearings, different ball structures, such as cylindrical hybrid slewing bearings. The above-mentioned various types of bearings are classified into different types according to whether they have teeth and gears, such as toothless type, external tooth type and internal tooth type. What are the bearing characteristics of slewing bearings? According to different structural characteristics, the rotary table bearing can satisfy the needs of the working host under various load conditions.
Touch ball turntable bearings have high dynamic load capacity. Compared with a single-row spherical turntable, the load-bearing capacity of a double-row spherical turntable with different diameters is greatly improved. Interspersed cylindrical roller turntable has a higher static load capacity. The spherical combined slewing bearing has a greater ability to accept axial and radial loads and overturning torque, while ensuring a certain degree of rotation accuracy.
