Análise de resistência de eixos, engrenagens e chavetas da caixa de transmissão de um veículo baja

Abstract

The present work aims to perform a resistance analysis of the main transmission box elements of a Baja prototype used by the IFPI-Baja team. For this, the analysis of the resistance of the axles, gears and keys that composes the transmission box of the Baja prototype was made. It was used a bibliographical and documentary research consulting the main references that bring a methodology for determination of forces, tensions and determination of the safety coefficients of the main components of the transmission box. For this analysis, the safety coefficients were first calculated for each axle of the transmission case, afterwards the voltages and safety coefficients were determined for each key and finally it was determined the voltages, safety coefficients against bending failure and surface failure. For each gear was performed a simulation of a gear considered critical because it was subject to highest values of requests. Therefore, was possible to obtain a comparison between analytical and computational results.
