Plain Bearing Damage
MetadataShow full item record
Correct diagnosis is the first step towards improved reliability. The paper investigates in some detail, cases of bearing damage in turbomachinery, for plain cylindrical and tilting pad journal and thrust bearings. Types of damage discussed include: cracking, pitting, scoring, wiping and thermal faceting. These are related to the causes which include overloading, overheating, corrosion, electrical discharge, dirt, static fretting, lubrication arrangements, assembly and adverse features of design and environment. Experimental and theoretical studies have lead to a better understanding of bearing behavior.
