Question 59Gas Turbine - 1st Asst/Chief70% to pass
The lubrication principal used by the Kingsbury thrust bearing is which of the following?
AI Explanation
The correct answer is D) Wedge-shaped oil film.
The Kingsbury thrust bearing uses a wedge-shaped oil film to support the load. As the bearing shaft rotates, the wedge-shaped oil film is formed between the stationary and rotating surfaces, which generates a high-pressure region that can support the applied thrust load. This wedge-shaped oil film is a key principle that allows the Kingsbury thrust bearing to effectively and efficiently support axial loads.
The other options are incorrect because they do not accurately describe the lubrication principle used by the Kingsbury thrust bearing. A cylinder-shaped oil film, a free sliding oil film, and a square-shaped oil film are not the mechanisms used in this type of bearing.
