Influence of Manufacturing Process on Stress Distributions in Mechanical Parts

Abstract

The presented paper deals with the influence of manufacturing process on the stress state of mechanical parts. The problem is presented in the assembly of the belt drum. The connections of individual parts are realized by press fitting and welding technology. The practical use of the belt drum shows the initiation of cracks in the weld body. The presence of press fitting connection in the structure is marked as the origin of high stresses in the weld body. The paper proposes the new assembly method in order to reduce the stress level in the weld structure and points the assembly method as one of important factors influencing the stress state of mechanical parts.
