Mejora de los módulos de simulación de fallas en ruedas dentadas del rotor kit del laboratorio de diagnóstico técnico y eficiencia energética de la Facultad de Mecánica de la ESPOCH

Abstract

This technical project is focused on the improvement of the modules due to the need for more reliability of the results obtained in the simulation of failures in gear wheels. We began by visualizing the problem based on getting undesirable harmonics when analyzing a characteristic failure mode and identifying the general objective, improving the simulation modules of cogwheel failures of the Diagnostic Laboratory: technician and Energy Efficiency of the Faculty of Mechanics of the ESPOCH. For this project, the preliminary condition of the modules was analyzed, and their initial condition was established by means of functional tests of the already existing modules with the help of the vibrachek 200 IDEAR and the MAINTraq Predictive software; in this way, the valuable components were identified for the improvement of the modules, in turn, the different failure modes to be simulated were chosen with the help of the Charlotte charts to determine their characteristic harmonics. To redesign the module, a design software was applied in which the components to be used in the construction and assembly of the modules were dimensioned and selected, ending with the performance tests in which it was possible to clearly distinguish the differences between the spectra and waveforms of each failure mode represented. In this way, it is concluded that the improvement of the module allowed for reducing the amplitude of the undesirable harmonics and, thus, recognizing the harmonics corresponding to the failure mode analyzed. It is recommended that for the taking of measurements, the necessary number of samples are taken to be able to analyze spectra in more detail.
