Implementación de un módulo de simulación para el diagnóstico vibracional de fallas en engranajes para el rotor kit del laboratorio de diagnóstico técnico y eficiencia energética

Abstract

This technical project was carried out in order to implement a gear failure simulation module; in which students can carry out vibrational analysis studies within the Laboratory of Technical Diagnosis and Energy Efficiency of Mechanics Faculty. It began with the analysis of the condition of the existing module according to the ISO 9000 standard to identify its characteristics, operation and dimensioning; With the collected data, measures were standardized and new components were designed in the academic SolidWorks software to incorporate different failure modes in a single system, thus generating a kit rotor. Established design changes allowed the components to be machined on a precision CNC lathe, assembled, and finally built. Taking into account ISO 20816-1 Standard. The functionality of the implemented module was determined; executing work tests at normal conditions, with broken gear tooth, meeting of teeth and linear misalignment every 0,25 mm. These analyzes were performed on the Vibracheck 200 ABG in conjunction with the MAINTraq Predictive free license software, determining different spectra and waveforms at a frequency of 60Hz. For the quantitative analysis, the least squares method was used, showing a significant difference in the trend lines for each failure mode analyzed. In this way, it is concluded that this implementation will allow the application of Charlotte letters, which present typical spectra of gears problems, which help to determine, through the harmonics and gear frequencies.The problem that is being caused in the gears teeth of transmission components. For vibrational analysis is recommended to generate an adequate amount of data to check the trend lines variation and appreciate the differences between the determined spectra.
