Desarrollo de un procedimiento para el diagnóstico de crucetas a través del análisis de vibraciones en trenes de potencia posterior y su contribución al mantenimiento predictivo.

Abstract

In this research project, the diagnosis of crosspieces was made through the analysis of vibrations in subsequent power trains and their contribution to predictive maintenance. First, the current situation of subsequent power trains and cross-section investigation was analyzed. The failure modes of each one of the points and the spectra of the subsequent transmission system CN V, CN H, and CN A were performed in the variable speed employing a secondhand crosshead, a new crosshead, and a broken crosshead. For the Measurement of each failure mode, Vibrachek equipment was used to determine the level of vibration. Data was collected to be transferred to the MAINtraq Predictive program 2.1 to assess the exact point where the level of vibration is an acceptable value to be interpreted. For the analysis of the reliability of the experimental data, the SPSS software was used, the value obtained from Cronbach's alpha was greater than 0.9, which determines that the data is in an excellent level of acceptability, proving that the data used is very consistent and solid statistically. By the data obtained applying the analysis of vibrations to the crossheads in the 3 specific planes, it was determined that their loss can be monitored since their harmonics are increased according to the damage that occurs therein. Therefore, it is reliable to apply the process of vibration analysis at crossheads for predictive maintenance.
