Diseño y construcción de un banco de pruebas para el diagnóstico de fallas en sistemas mecánicos por transmisión de bandas utilizando un análisis comparativo de espectros de vibración

Abstract

In this curricular integration work, the design and subsequent construction of a test bench for the diagnosis of faults in mechanical systems by band transmission was carried out using a comparative analysis of vibration spectra, in order to provide to the students the necessary tools to acquire knowledge and skills in topics such as; vibration measurement and analysis, pulley alignment using specialized instruments, analysis of the influence of belt tensioning on transmission efficiency, among others. This through the donation of the equipment and tools that make up the test bench, as well as of the implementation of guides to carry out laboratory practices. The implementation of the test bench started from the use of the QFD methodology, with which it was possible to analyze and solve the requirements of the students, in turn it was allowed to contrast the proposed design with equipment of similar characteristics, thus establishing minimum parameters that had to be fulfilled to determine the best alternative solution. The specialized software design of each of the elements that make up the test bench, as well as the subsequent development of its mechanical plans are based on its future construction. The process does not end with the construction and assembly of the constituent elements of the test bench, as it continues with the validation of data obtained by performing various tests, the same that make up the laboratory guides, thus strengthening the theoretical-practical teaching so that future professionals have solid foundations for a correct development in their work activities.
