Comparación del consumo energético de la desalineación de ejes con diferentes acoples flexibles utilizando regresión lineal múltiple

Abstract

The general objective of this research work was to relate the variation in energy consumption due to parallel shaft misalignment and angular shaft misalignment with the jaw coupling, the donut-coupling and the Polyurethane-sheathed coupling, using multiple linear regression. The sample size was defined using the probabilistic equation for an infinite population, obtaining n=12. The data collection technique was assisted by a laser alignment equipment and another for analysis of the quality of electrical energy. A laboratory observation was made through a module that allows misalignment to be forced and applied to the different types of couplings. The increase in energy consumption measured in Watts of a 5 HP three-phase motor, subjected to a load of 2,974 kW that represented 80.38% of its capacity, was observed. As it was misaligned in a parallel, angular and combined manner. In conclusion, the motor using the jaw coupling, as a movement transmission element. It presented an average energy consumption of 3 kW with an increase of 26 W, in conditions of parallel misalignment. Likewise, it presented an average energy consumption of 2,982 kW with an increase of 8 W, in conditions of angular misalignment. Similarly, it presented an average energy consumption of 3,003 kW with an increase of 29 W, in conditions of combined misalignment. It is recommended to carry out a research of the service life for the coupling with a polyurethane-sheathed and for the donut coupling in the same manner to develop a comparison using a magnetic type coupling, an electromagnetic type coupling and a pneumatic type coupling.
