Question 1 of 27070

If a spring bearing begins to run at an abnormally high temperature, you should __________.

🔍 Key Concepts

• Purpose and design of a spring bearing in a propulsion shaft line • Typical first actions for abnormal bearing temperature in machinery operation • Risks of sudden shaft stoppage or reversal to the shafting and bearing

💭 Think About

• Which action best controls the local problem at the spring bearing itself rather than changing unrelated systems? • What is the safest immediate way to reduce temperature and load on the bearing without causing additional mechanical stress? • How would you normally respond to a bearing running hot: completely stop, reverse, or gradually reduce load and improve cooling?

✅ Before You Answer

• Identify which options act directly on the overheated bearing rather than the general lube oil system • Eliminate any option that could cause sudden high stresses in the shaft or bearing (like abrupt stop or reversal) unless absolutely necessary • Ask whether the option provides both load reduction and additional localized cooling to the affected bearing

Question 1 of 27070

If a spring bearing begins to run at an abnormally high temperature, you should __________.

increase the water flow to the main lube oil cooler

immediately stop the shaft to prevent seizing

reduce the shaft speed and supply emergency cooling water to the spring bearing housing

reverse direction of the shaft to flush out the bearing
