What is the structural form of slew bearings?
The slewing bearing is a medium and large bearing with a special structure that can simultaneously bear large axial load, radial load and overturning moment and other comprehensive loads.
Generally, the slew plate bearing itself has mounting holes, lubricating oil holes and sealing devices, which can meet the different needs of various types of hosts working under different working conditions; on the other hand, the slew plate bearing itself has a compact structure and guides rotation. With the characteristics of convenience, easy installation and easy maintenance, it is widely used in medium and large slewing devices such as lifting and transportation machinery, metallurgical machinery, mining machinery, construction machinery, port machinery and automated assembly lines.
Slewing bearings can be divided into four-point contact ball slewing bearings, double-row reducing ball slewing bearings, crossed cylindrical roller slewing bearings and three-row cylindrical roller combination slewing bearings according to different structural forms; the above types of bearings According to whether it has teeth and the distribution position of the teeth, it is divided into different structures such as toothless type, external tooth type and internal tooth type.
According to different structural characteristics, slew bearings can meet the needs of the working host under various load conditions. Among them, four-point contact ball slew bearings have a high dynamic load capacity, crossed cylindrical roller slew bearings have a high static load capacity, and three-row cylindrical roller combined slew bearings direct the increase in load-bearing capacity to the height direction of the bearing. , various loads are borne by different raceways and roller groups, so under the same stress conditions, the diameter of the bearing can be greatly reduced, so it has the characteristics of making the host more compact, and it is a turntable with high load-bearing capacity bearings.
