Diseño y construcción de una máquina para ensayo de engranes rectos sometidos a fatiga

Abstract

One the most important subjects of the study in the mechanical engineering career are the gears, where these are the fundament part of the rotative machine provide power and transmit movement. These find to small machines as clocks to a big machine in the industry. This is why the importance of gears. Given the value of the gear, it is intended to extend useful life, due to the fatigue that can be encountered due to the time of use, loads, and lack of maintenance. This project shows a theorist focus of different prototype for gears testing machines which have been developed in the world. Selecting the most suitable one that adapts to the required needs. Design is described and the materials are chosen taking the loads and the safety factors calculated analytically for the correct operation of the machine and precautionary operator safety. With the machine stated, an experimental analysis is performed. Aiming to inductively identify the result obtained when the gears with different working regimes are tested. Finishing with the conclusions and recommendations which find through the project.
