What is the role of the thrust bearing?

The role of the thrust bearing is to withstand the axial thrust of the rotor during operation, to determine and maintain the axial mutual position between the turbine rotor and the cylinder.

Turbocharger What is the role of a thrust bearing?

In general (the specific model structure will have a smile change) is stuck in the groove in the fixed sleeve seal, that is, you do not have direct contact between the seal parts, because the shaft seal is rotated together with the shaft, and the thrust The sheet is generally in a non-rotating working state, and the middle of the two is the action of the oil film thrust piece, which is to axially position the rotor to prevent the shaft of the rotor assembly (the turbine, the shaft, the impeller and the upper shaft seal and the like). Together with the floating bearing that prevents the radial movement of the rotor assembly, the complete positioning of the rotor is completed, so that the rotor of the supercharger rotates at the design position without being biased to rub against the intermediate body, the volute, the compression shell, and the like.

The role of oil in thrust bearing oil basin

Two functions: 1, cooling effect. 2. Lubrication.

What are the characteristics of thrust ball bearings?

1. It is a separable bearing with a contact angle of 90°. It can be installed separately and can only bear axial load.

2. The limit speed is low. The steel ball is centrifugally squeezed to the outside of the raceway, which is easy to scratch, but not suitable for high speed operation.

3. One-way bearing can withstand one-way axial load, and two-way bearing can withstand two-way axial load. 4. Thrust ball bearing with spherical race has self-aligning performance, which can eliminate the influence of installation error.
