Question 1 of 270705eccefa0bacbc34ba4d4708e

Which of the following construction methods would apply to the Babbitt lined, split-type, reduction gear bearings?

Question 1 of 27070

Which of the following construction methods would apply to the Babbitt lined, split-type, reduction gear bearings?

🔍 Key Concepts

• Split-type bearings and why they are made in more than one piece • Characteristics of Babbitt-lined bearings (soft lining, load distribution, ease of replacement) • How reduction gear bearings are mounted to handle heavy, reversing loads

💭 Think About

• Think about why a bearing would be made in split form: what maintenance or alignment advantages does this give? • Consider how pressure should be distributed on a properly mounted bearing: should the highest pressure be on a joint line or on a continuous surface? • Ask yourself whether reduction gear bearings need to be free to adjust slightly, or rigidly fixed with no ability to conform to shaft or gear movement.

✅ Before You Answer

• Check which options would help maintain proper oil film and load distribution on the Babbitt lining. • Eliminate any choice that would create high stress or pressure exactly at the split/joint faces of the bearing. • Consider which option best matches common practice for large marine reduction gears used in propulsion plants.

Question 1 of 27070

Which of the following construction methods would apply to the Babbitt lined, split-type, reduction gear bearings?

They are always mounted with the split in a horizontal plane.

They are rigidly mounted and dowelled in their housings.

They are split into four equal sized segments.

They are secured in their housing so pressure points will occur at the joint faces.
