Construcción de un módulo de pruebas para el estudio del tensado óptimo de las correas trapezoidales mediante análisis vibracional y energético, para la Facultad de Mecánica de la ESPOCH.

Abstract

The present work cerned out the creation of a test module for the stiidy of the optimal tightening of v-belts, in order to contribute with student learning and help the laboratory equipment of technical diagnosis of the engineering of maintenance school. The development of this work started by modeling the test bench in the Solidworks software, the selection of pulley, v-belt, electric motor and altemator, the static simulation of tensión píate and finally executed the mounting and start-up of operations. Determining the optimal tightening of v-belts of transmission system was caícuiated the tensión optimum by means of a static analysis of the system and analysis slippage, analysis of energy quality and diagnosis of vibration, with the methods of vibration frequency and constant arrow; the equipment of vibracheck 200 ABG and the Fluke 435 series II were used for the measurements. ít obtained that the transmission system is more efficient if it is working with high performance v-belts and the proper method for tensioning is the frequency of vibration. The results obtained through the analysis experimental were that it could estabíish an equation empirical that allows calculating the sliding dependí ng on the tensión of the band. Test module provides facilities for the study of tensioning the v-belts. It recommends storing in a place clean and dry, free of dust, vibrations, gases and agents corrosive and with a humidity relative of the air not higher to the 60%.
