Which of the following construction methods would apply to the Babbitt lined, split- type, reduction gear bearings?
AI Explanation
The correct answer is D) They are rigidly mounted and dowelled in their housings.
Babbitt-lined, split-type reduction gear bearings are designed to be rigidly mounted and dowelled in their housings. This provides a secure and stable mounting that prevents pressure points from occurring at the joint faces, which would be the case if they were simply secured in the housing (option A). The split design allows for easier installation and maintenance, but the bearings are not split into four equal segments (option B) or necessarily mounted with the split in a horizontal plane (option C).
