Which of the following methods is used to securely fasten the babbitt lining of a reduction gear bearing to its shell?
AI Explanation
The correct answer is B) The babbitt is centrifugally spun into the bearings or cast under a pressure head.
This is the correct answer because the babbitt lining of a reduction gear bearing is typically secured to its shell by being centrifugally spun or cast under pressure. This process ensures a tight, secure fit between the babbitt and the bearing shell, preventing the babbitt from becoming dislodged during operation.
The other options are incorrect because:
A) The babbitt does not have a crescent-shaped pocket cast into it.
C) The babbitt is not held in place solely by the hydrodynamic oil wedge.
D) The babbitt is not relieved at the split and held in place by locking pins.
