Análise comparativa entre coroas dentadas de aço e alumínio empregadas na transmissão de uma moto de competição

Abstract

In this thesis it was shown the performance comparison between two sprockets made of different materials, being one of them made of 1045 steel and the other one made of 7075 aluminum. Both of those parts are compatible with the transmission system of the sportive motorcycle S1000RR of the great Deutsche brand BMW. This comparison was made through a case study, and to do that it was made some laboratorial tests and simulations on engineering software to evaluate the mechanical properties and the durability of each material, to determine which one of them has the best performance and life span. The difference between them is harnessed to their construction materials, so that they were tested on the same use conditions. In this way, the objective of this work is linked to prove that the aluminum sprocket has the necessary properties to handle with the efforts of use, as it is done on the original option
