Análisis del diseño, ruido y vibración de maquinaria desfibradora de Ixtle de Lechuguilla

The purpose of this study is to analyze the main components of a typical Lechuguilla Ixtle shredder machine, present in most of theejidos dedicated to this activity in the northeast of Mexico, and to determine the opportunities for redesign its main parts, also thesound and vibration levels for evaluate their magnitude and determine the severity and impact. To achieve this objective, the DFXmethodology was applied to Lechuguilla Ixtle shredder machine knowing the main parts that are susceptible to redesign, this typicalmachine was also compared against a bench test, carried out in a workshop with a lower power motor, with which were made testsfor noise and vibration, in both cases the analyzes are perform out with the same intention of achieving an improvement in itsefficiency. The results of the DFX methodology, as opportunities for redesign are: the safety of operation, the input and outputmechanisms, speed working when defibrating two Cogollos, lightening the structure, motor capacity depending on the design of thedefibration roller, and the form of maintenance and inspection. Finally, in the analysis of noise and vibrations, there areopportunities for improvement in the design of the machinery drum, placing a guard (cover) that helps to reduce noise levels, andreviewing the alignment of the axes the machinery so as not generate vibration outside the allowable ranges
