Failure analysis of a gear reducer used on pre-stressed concrete (PC) wire production

There are many application areas of prestressed strand wire production from steel wires in industry. Winding mechanisms in steel strand production facilities are exposed to high stresses. In this study, failure analysis studies are included as a result of failure to a gear mechanism in strand produc...

description	There are many application areas of prestressed strand wire production from steel wires in industry. Winding mechanisms in steel strand production facilities are exposed to high stresses. In this study, failure analysis studies are included as a result of failure to a gear mechanism in strand production construction. In this context, the fracture surfaces were examined under the scanning electron microscope (SEM) analysis. The heat treatment history of the fracture zone and the main body was investigated and the microstructures and hardness measurements were compared. Failure root cause analysis was carried out. As a result of the study, it was determined that fatigue cracking occurred with the effect of improper heat treatment and caused fracture. It has been understood that the inhomogeneity of the hardening depth causes fracture with the effect of increasing stresses and cycles.
