This bachelor thesis deals with the structural design and comparative analysis of a shaft screw conveyor with a solid helix and a shaftless spiral conveyor. Both systems are dimensioned for identical operating parameters. The thesis includes a theoretical introduction to the issue, the selection of suitable materials considering high material abrasiveness, and complete functional and capacity calculations, including trough and drive design. Furthermore, the bearing arrangement design and strength analysis of stressed components are performed. In the final section, both concepts are critically compared in terms of torsional stiffness, operational reliability, and production costs. The output of the thesis is the drawing documentation containing assembly drawings of both conveyors at the same scale.
Comparison, conveyor trough, inclined transport, screw conveyor, screw flights, shaftless spiral, spiral conveyor, worm shaft.
