Projeto e construção de um dispositivo de ensaio de engrenagens

Abstract

This work presents the design, construction, and experimental validation of a Gear Testing Device (GTD), developed to evaluate the tribological performance of cylindrical gear pairs under different lubrication conditions. The equipment was designed with a focus on modularity, disassemblability, and precise instrumentation, enabling comparative testing between industrial lubricants. The methodology encompassed the complete mechanical design, including load analysis, fatigue life assessment, and in-lab manufacturing of all components using conventional machining processes. Experimental tests demonstrated the device’s ability to simulate real operating conditions, monitoring parameters such as torque, temperature, and wear through integrated sensors. The results confirmed the system’s effectiveness in detecting typical gear failure mechanisms, such as micropitting and abrasive wear, thereby validating the technical proposal. In addition to fully meeting the design requirements, the GTD proves to be a robust and highly applicable academic tool for future studies in tribology and mechanical power transmission engineering.
