Criação de um plano de contingência para redutores de velocidade para um setor de uma empresa moageira de soja da região dos Campos Gerais

Abstract

Preventive and predictive maintenance techniques are extremely important for a proper functioning of an industrial plant, however due to adverse operating conditions there is always the possibility for a catastrophic failure to occur. The present work deals with the elaboration of a contingency plan aimed at corrective maintenance, in order to reduce the intervention time on speed reducers of critical machines. With the systematic cataloging of the equipment, an interdisciplinary committee with members from the production, quality, maintenance and safety sectors, the criticality levels were listed based on safety, process and costs. As a result of this cataloguing, a centralized spreadsheet with important data of the plant’s speed reducers was created. Using the database, it was possible to map out a strategy to allocate a less critical gearbox in order to give continuity to the operation of a more critical equipment, thus reducing the mean time to repair (MTTR).
