Abstract

This work was conducted because of a shaft fatigue failure occurring on the existing double suction fan for hot gas applications at the Cementos Cienfuegos S.A Company. The particularity of this shaft is that the failed section is opposite to the motor where no torsion is applied but only shearing and bending. Some shaft sections revealed much less stress than the failed area; thus it is possible to transmit the bending load through tenoning due to interference from a bar section of the same steel. The diameter of the tenon was determined based on the relationship between rigidity of the annular section on the shaft side to be tenoned and the robust circular section to allow increasing the strength of the repaired section.
