RESUMO

The crescent implementation, by brazilian industry, of predictive maintenance techniques demands, from vibration analyses processes, more capability for supplying information on the state of equipment. Among the existent analysis procedures for rotative machines, the vibration analysis is one of the more used, being nowadays, present in a wide portion of important industrial sections in Brazil (as the cellulose pulp and paper for instance). This makes, therefore, more and more important to explore all of the possibilities of this method. This work begins an investigation about the relation between vibration (mechanical signature) and lubrication of rotative machines. As a starting point of this study, it tries to evaluate the effect of the variation of the viscosity of the lubricant on the vibration signature of a gear box. The work presents a large experimental database, discusses several methods of signal processing and presents a characteristic of the vibration signal capable to identify alterations in the viscosity of the lubricating oil in the tested equipment.
