INVESTIGATION OF THE TRIBOLOGICAL PROPERTIES OF JOURNAL BEARING UNDER WEAR TEST

Sumeet A. Datar, Prof. P. R. Sonawane

Abstract

Occurrence of the friction and wear at machine parts of rotating system which run together, affects the efficiency of machine negatively. Because of its simplicity, low of cost and efficiency journal bearings are used widely in industry. It is difficult to accurately predict the component life due to wear and friction. This attempt is to study the influencing parameters like load, speed and temperature, friction coefficient during wear test. The main objective to the paper is to study wear rate of Babbitt journal bearing. The Babbitt metal is tested in lubricated condition using 20W40 oil under Pin-on-Disc Tribometer. Results found that, metals prone to wear at considered operating conditions due to change in frictional coefficient at contact surface.
