Question 355Steam Plants - 1st Asst/Chief
70% to passIn the thrust bearing assembly illustrated the total oil clearance can be correctly decreased by _______________. Illustration SE-0007
Adecreasing the thickness of the adjusting ring
Bincreasing the thickness of the adjusting ring
Cincreasing the thickness of the filler piece
Ddecreasing the thickness of the filler piece
AI Explanation
The correct answer is A) decreasing the thickness of the adjusting ring. The total oil clearance in the thrust bearing assembly can be decreased by decreasing the thickness of the adjusting ring. This is because the adjusting ring is used to set the clearance between the thrust collar and the thrust bearing. Reducing the thickness of the adjusting ring will bring the thrust collar and bearing closer together, thus decreasing the total oil clearance. The other options are incorrect because increasing the thickness of the adjusting ring or the filler piece would increase the clearance, and decreasing the thickness of the filler piece would not directly affect the clearance between the thrust collar and bearing.
