Análise de vibrações e o aumento da vida útil dos rolamentos

Abstract

This study aims to demonstrate the importance of th e adoption of vibration analysis to increase bearing life and therefore reducing cos ts and demands of maintenance related defects and failures as causes rolling mach ines in the merchant vessels . The bearings are mechanical supports axis with the func tion to enable them to make the rotational movements more easily by reducing fricti on between moving parts of equipment. The most common causes of failures in ro tating machinery are related to bearings. To meet the current mission of maintenanc e to ensure reliability and availability of machines is the need for adoption o f predictive maintenance techniques that allow the detection and localizatio n of failures or reduced performance of the equipment enabling a planned cor rective maintenance and not an emergency corrective maintenance that usually resul ts ins serious consequences or high costs for equipment of the same plant of equip ment which failed or poor performance. Therefore the vibration analysis will allow the bearings to run for a longer service life though monitoring and that corr ective action can occur in a planned way with the equipment bearings.
