Dimensionamento de uma caixa de distribuição de potência para um implemento agrícola autopropulsado

Abstract

This study was designed to measure a power distribution box of a self-propelled sprayer. Developed in order to replace a transmission helical gears, this transmission was built from professional experience using common techniques and standard components in the construction of transmission by belts and pulleys. While there are few references on the subject, the project development from the classical literature of machine elements and technical catalogs of components was possible. Thus, it was observed that the belt system was not sufficient to transmit all the engine power, necessitating addition of 3 spare channels. From this it was possible to scale the axes of the set, which could be manufactured in low-carbon steel non heat-treated, and 22% reduction of the material. His mancalização before made by tapered roller bearings and bearing forged steel can be replaced by ball bearings mounted in machined bearings, reducing approximately 50% of the final cost. The components were then manufactured and or acquired in accordance with the specifications of the project and engaged in a prototype. After the period of 50 hours testing time due to the first review of the equipment, an analysis on the prototype found that the new components and settings corresponded to developed calculations.
