Diseño y construcción de un banco de pruebas para diagnosticar fallas en engranajes mediante espectros vibracionales para el Laboratorio de Mantenimiento de la Facultad de Mecánica.

Abstract

A Test Bank has been designed and constructed to diagnose faults in the gears, through the analysis of the vibration spectra at the ESPOCH Mechanic Faculty so as to support practical knowledge for students studying the Vibration Analysis Subject Matter. The most common faults in the gears were investigated. An alignment work was performed to eliminate the existing angular and parallel alignment with the OPTALIGN PLUS equipment belonging to the Faculty, so as to reach an excellent aligning result reflected in the gear spectra in good condition . With laser technology of this equipment time is saved. Later test established in the investigation work are carried out without confusing the spectral found in the different practices. In the test different routers were performed with the TRENDLINE software. The thesis was adapted to the parameters and conditions of the existing equipment to observe the spectral characteristic of the faults within the frequency interval allowed by the equipment. For the spectra obtainment test were carried out with the gear kit with common faults. Later their analysis was conducted. This way they were related to the investigated theory. From the results of each measurement the gear frequency and the natural frequency were analyzed under two fundamental parameters for the gear diagnosis with the measurements in their the three sense; the axial, radial and tangential ones
