Development and Verification of Test Equipment for Wear Resistance of Water-Lubricated Bearing of Naval Vessel

Recent trends have shown an increase in premature excessive wear, abnormal noise, and abnormal vibrations in water-lubricated bearings used in naval vessels. Despite this, there is no established standard or testing procedure to verify the wear resistance performance of these bearings. This paper addresses this gap by developing experimental equipment that simulates the actual operating environment of water-lubricated bearings in naval vessels and conducting tests to evaluate their wear resistance performance. The test results successfully replicated the phenomena observed in actual naval vessels. Additionally, differences in wear resistance performance were identified based on the materials of the water-lubricated bearings. To cross-validate these results, reciprocating wear tests and taber abrasion tests were performed, confirming the consistency of the test trends. This study aims to improve the quality of water-lubricated bearings used in naval vessels and prevent premature excessive wear and related issues
