EXPERIMENTAL-ANALYSIS OF JOURNAL BEARINGS

This study presents a comprehensive technique, which could be applied to almost any rotating equipment to identify and diagnose journal bear ing problems that relate to metal-to-metal bearing surface contact. Or bital measurements that describe bearing parameters in different modes of operation were experimentally obtained and analyzed. Such paramete rs may include. attitude angle, minimum oil film thickness, and the po ssibility of metal-to-metal rubbing occurrence. The general outline of the presented experimental technique was substantiated using the Raim ondi-Boyd well-documented design charts and good correlation between e xperimental and analytical results was obtained.
