What is the role of the thrust bearing?
The role of the thrust bearing is under the rotor axial thrust in the running, to determine and maintain the steam turbine rotor and cylinder between axial position to each other.
The role of the thrust bearing in the turbocharger?
In general,
The specific structure of different type will be a smile)
Is stuck in a fixed set of the groove in the shaft seal, which is what you said there is no direct contact between sealing parts, because the shaft seal is with shaft rotation, and the thrust piece is not working condition, the middle is a function of oil film thrust sheet, is to make the rotor axial positioning, to prevent the rotor fitting (
Turbine, shaft, impeller and shaft seal rotating components such as a general designation)
Axial string move and prevent the rotor radial motion of floating bearing tandem fitting, complete the full positioning of rotor, the supercharger rotor position in the design of rotating, not biased and intermediates, such as eddy shell, shell friction thrust bearing oil basin to the function of CPC two: 1, the cooling effect.
2, lubrication.
What are the characteristics of 1 thrust ball bearing.
This type of bearings is separable, contact Angle 90 °, can install respectively, can only carry axial load.
2.
Limit rotational speed is low.
Steel ball and centrifugal force to get outside, easy to scratch, but not suitable for high-speed operation.
3.
One-way bearing can withstand one-way axial load, two-way bearing can be subject to bi-directional load.
4.
With a spherical seat thrust ball bearing with self-aligning performance, can eliminate the influence of the installation error.
