Definição de um sistema de sincronizador para reversor mecânico de baixo custo para rabeta

Abstract

Due to the immensity of rivers present in the Amazon make boats the main means of locomotion of people and goods, most boats present in the region are made only by hand, but for large locomotions many of these are provided with engines being the simplest famous ‘’rabetas’’. Therefore, the aim of this work is to select a simple and sturdy reverser synchronizer system that can be produced with simple machining machinery from a real workshop. To this end, a study will be done on types of transmissions, gears, joints and sizing of keys. We will also explain a little about the types of vessels and their components in order to broaden naval knowledge and the functionality of a reverser applied to a tail. From this review we determined two types of joints between the hub and the axis that can be applied to the synchronizer that are striated profile and sliding key, from this delimitation the study is made to find out which one is the most economically viable. It was found that using the sliding key is the best option. Once the keyed joint is defined, it is then dimensioned by applying the maximum motor torque and safety factors. The dimensioned key is relatively small and as the other components have not been defined it has been found to be oversized at the end increasing the strength of the assembly and the service life.
