Slewing bearing manufacturers introduce you to the knowledge points of slewing bearings
Today, the slewing bearing manufacturer will introduce you to the knowledge points of slewing bearings. Friends who are interested in this, take the time to learn about it!
Slewing bearings, also called slewing bearings, are large, uniquely constructed rolling bearings that can bear comprehensive loads such as large radial loads, tangential loads, and overturning moments at the same time.
1. Structure classification:
(1) Usually, it contains mounting holes, grease holes and sealing equipment, which can meet the different requirements of various servers under different working conditions. The rolling bearing itself has the characteristics of compact structure, convenient guidance and rotation, simple installation and very easy maintenance.
(2) The common structural forms of this rolling bearing include single and double row, double row four-point contact ball slew bearings, single and double row angular contact thrust ball slew bearings, crossed cylindrical rollers and crossed cone roller slewing plates. Bearings, three-row cylindrical roller slew bearings, ball-cylindrical hybrid slew bearings and other different structural forms. The above various rolling bearings are divided into different structures such as toothless type, external tooth type, and internal tooth type according to whether they are toothed and the distribution position of the transmission gear.
2. Load-bearing characteristics
(1) Rotary bearings can meet the requirements of servers working under a variety of different load conditions based on different structural characteristics. Among them, the four-point contact ball slewing bearing has a high dynamic load capacity. The load-bearing capacity of the double-reaction ball roulette is greatly improved compared to the single tennis roulette.
(2) The crossed cylindrical roller disc has a high static load capacity. Ball-column combined slew bearings have a large ability to bear axial and radial loads and overturning moments while ensuring a certain rotation precision.
