The Effect of Exploitation Conditions on the Damage of a Roller Reducer Toothed Shaft and Its Repair
Journal Title: Machine Design - Year 2018, Vol 10, Issue 4
Abstract
This paper describes repair method of the toothed shaft of roller reducer located in Steelworks Smederevo facility, as well as the effects of exploitation conditions that have led to damage i.e. shaft fracture. After more than 15 years of in-service exploitation the shaft fracture has occurred at the bearing position. The fracture occurred due to blocking on the roller driven by this shaft. In order to restore the working capabilities of the shaft, the repair welding procedure has been established. Additional difficulties during establishing repair procedure were caused by the fact that the base material of the shaft was unknown, so certain assumptions were made (e.g. assumption of base material). Application of repair welding has resulted in significant direct and indirect savings in comparison to the purchasing of a new shaft.
