Diseño y modelado 3D de un elevador inclinado helicodal de granos.

Abstract

The main objective of this work is the development of an inclined helical elevator for corn grains. Initially, the types of endless screw conveyors and their main characteristics were presented. When looking for distributors of this equipment in the market we had a broader idea of the technical specifications and prices they present, and with this data, the house of quality was created. The main elements of the elevator, such as the helical shaft and the gear motor, are sized based on: the type and load of corn that will be transported, the calculation of the total power necessary to lift these grains, the angular speed, and the critical torque. The catalog designs of the gear motor and the flexible coupling are obtained, in the first instance the hollow shaft of the helical screw is designed, performing a static analysis, and thus obtaining values that allow the subsequent selection of the bearings at the entrance and exit of the helical shaft with their respective bearings, in addition, this analysis allows obtaining forces and therefore a safety factor for the helical screw. The rest of the parts are designed, drawings and the assembly drawing are designed, based on the references and then the costs of materials, manufacturing, and the indirect items that are included in the preparation of all the elements of the elevator to obtain an estimate of the cost of manufacturing an inclined helical grain elevator.
