| Popis: | The objective is to study fatigue failure of gears and bearings during processing of rebars and evaluate their performance under cyclic stresses. Mechanical vibration was measured on gears and bearings to determine efficiency and to avoid fatigue failure of components. These components are used during hot rolling to plastically deform steel billets and are exposed to cyclic and variable load stresses. The total amount of energy loss in the form of mechanical vibration was determined, and it was concluded that the materials selected for gears and bearings complied with the design criteria by failing progressively and not suddenly. Consequently, it was also concluded that the energy efficiency on reheating is strongly affected by fatigue failure of any of the components during hot rolling. |
