Function of thrust bearing

What is the function of thrust bearing?
The thrust bearing is used to bear the axial thrust of the rotor during operation and determine and maintain the axial mutual position between the steam turbine rotor and the cylinder.
What is the role of thrust bearing in turbocharger?
Generally speaking (the structure of different models will change with a smile) is stuck in the groove in the fixed sleeve shaft seal, that is, there is no direct contact between the sealing parts, because the shaft seal rotates with the shaft, while the thrust plate generally does not rotate. In the middle of the two, the oil film thrust plate is used to position the rotor axially and prevent the rotor assembly (turbine, shaft The axial series movement of the impeller and its upper shaft seal and other rotating parts (collectively referred to as "the floating bearing") and the floating bearing to prevent the radial series movement of the rotor assembly complete the complete positioning of the rotor, so that the rotor of the supercharger rotates at the design position and will not be biased to friction with the intermediate, volute, pressure shell, etc
Function of oil in thrust bearing oil basin
Two functions: 1. Cooling. 2. Lubrication.
What are the features of thrust ball bearings
1. It is a separable bearing with a contact angle of 90 °, which can be installed separately and can only bear axial load
2. The limit speed is low. The steel ball is squeezed to the outside of the raceway with centrifugal force, which is easy to scratch, but not suitable for high-speed operation
3. One way bearing can bear one-way axial load, and two-way bearing can bear two-way axial load
4. The thrust ball bearing with spherical race has centering performance, which can eliminate the influence of installation error
