Thrust bearing
Thread Content
How do thrust bearings work, and what is their structure? I’d like to ask the experts here
Bearings that can generally withstand a certain amount of axial force are often of conical design, with the specific choice depending on the circumstances.
The function of a thrust bearing is to bear the axial forces on the rotor; in centrifugal pumps, spherical or tapered angular contact bearings are used； For centrifugal compressors and turbines, it is the Mitchell or Kingsbury bearings that are used, with the thrust disc on the rotor transferring the axial force of the rotor to the bearings.
I also spent quite some time thinking about this thrust bearing. Although I have seen pictures, there are also schematic diagrams. But I’ve never been able to figure out how it works. . . Even if you ask, you won’t be able to understand clearly. . It’s impossible to find the way in. Same request.
To prevent the rotor from moving back and forth during operation, the axial position of the thrust disc is maintained by thrust bearings. The function of these thrust bearings is to bear the axial forces on the rotor, restrict its axial movement, and keep the rotor in its proper axial position within the cylinder.
The information available on forums is not always comprehensive. For simple facts like those related to imported bearings in Wuxi, one can simply search on Baidu – there’s plenty of information there, and it’s quite thorough as well
Buy a classic textbook on mechanical design; read it and you’ll understand
What is the main difference between Mitchell and Kingsbury?
