Manutenção preventiva: aplicação de um plano de manutenção para o redutor do yaw de um aerogerador. 2021. 46f. Trabalho de Conclusão de Curso (Graduação em Engenharia Mecânica) - Centro Tecnológica, Universidade Federal do Rio Grande do Norte, Natal-RN, 2021.https://repositorio.ufrn.br/handle/123456789/38061The present work aims to create and implement a maintenance plan for the yaw reducer of a wind turbine. In the presented context, maintenance appears as a strategic function to solve and prevent failures, increasing the availability and reliability of the wind turbine. For this, a case study was carried out in a wind farm in the state of Rio Grande do Norte. This is descriptive research of a quantitative nature. Characteristics of the wind turbines and how the maintenance plan were carried out are described. In the end, it was possible to conclude, through the last oil collections, that the maintenance plan was effective, as it was found that the yaw reducer did not present any failures, certifying its success after its implementation.ManutençãoAerogeradorLubrificaçãobachelorThesis
