Construcción de un módulo de pruebas para simular modos de falla en sistemas de transmisión de potencia con polea para el laboratorio de diagnóstico técnico.

Abstract

The study aims to build a test module to simulate failure modes in pulley power transmission systems. This test module provides a useful training for students of Maintenance Engineering School due to module allows to carry out different pulley misalignments such as: parallel misalignment, horizontal/angular misalignment and vertical/angular misalignment. First, to build the module, an adequate items selection was established such as: a squirrel-cage motor with 1 Hp power, a 32 A - 12 volt alternator which will provide the system load, the movement is transmitted by the V-belt as well as two pulleys with a transmission ratio of 1:1. The methodology to make the different misalignment was developed, as well as a detailed procedure for the use of the equipment required for this study. Afterwards, a Vibration Analysis by using Vibracheck 200 ABG equipment and the energy quality study by using Fluke 435 II equipment were carried out. The module must ensure optimal operational conditions before to generate the different misalignments in order to have a characteristic spectrum as a starting point to start the misalignment. Trend Graph was made with the obtained values by means of the misalignments to show higher energy consumption as well as an overall vibration level (RMS) as the misalignment increases. It shows that the module performs the function for which it was designed.
