Resumen:
The aim of this work is to perform a thermographic study aiming to verify assembly failure by mounting in flexible claw type coupling, model GR 50. A research methodology can be characterized as applied, quantitative, explanatory, bibliographic and experimental type. For this, an experimental bench was built, containing a three-phase motor, shafts, bearings and the flexible coupling, without a load presence, to join two shafts with misalignments between them; 0.5, 0.74 and 1.18 mm. As a result of the tests performed, it was possible to notice that the temperature of the coupling increases the same proportion of the misalignments inserted, that is, the greater the misalignment, the higher the temperature recorded. This fact is best observed in the first 20 minutes of the tests. In view of these results, it is possible to affirm that the thermography can be used as a technique for detecting mounting faults by misalignment in the first minutes of the system operation.
