Implementación de un módulo de simulación para el diagnóstico vibracional de fallas en rodamientos para el rotor kit del laboratorio de diagnóstico técnico y eficiencia energética de la Facultad de Mecánica

Abstract

The objective of this research work was to implement a simulation module for the vibrational diagnosis of faults in rotor bearings for the kit of the technical diagnosis and energy efficiency laboratory, for which calculations were made in order to select the elements and subsequently carry out the comparison of the frequency values, and amplitude envelope with bearings in good and bad condition. First, the selection of the mechanical parts was carried out, based on certain technical considerations, then the construction of the module began, to carry out the tests by means of vibrational analysis, using the 6208-2RS1 bearing; Subsequently, a maintenance plan was carried out, based on the manufacturers' recommendations methodology, followed by a laboratory guide and an operation manual, taking into account criteria such as the students’ safety, the ease of interacting with the module and strengthening concepts. The comparison of measurements was made, giving as a result that the highest value of amplitude envelope for a bearing with BPFO frequencies is 0,386 gE, in the presence of BPFI frequencies. The most prominent value of envelope amplitude is 0,116 gE, and the highest amplitude values at BPFO and BPFI frequencies are 0,292 and 0,486 gE; the lowest values were obtained in the axial plane. It is concluded that for the bearing with the BPFO frequency, the best measurement point is the horizontal, for the BPFI frequency, the best direction is the vertical; and having the BPFO and BPFI frequencies, the best measurement planes are the vertical and horizontal. It is more difficult to detect faults in the axial plane. It is recommended to induce faults in other types of bearings to study their behavior when subjected to continuous work.
