Análise de consumo e custo de óleos lubrificantes no setor de manutenção de uma indústria do ramo metalmecânica

Abstract

Tribology it’s the science that studies the phenomena which happens in the contact between two surfaces which had your first citation in the scientific scope in the 1960’s. The application of this doctrine in the metalworking industries it’s very important, since its deficiency can cause several losses for the company, specially in their machines. The proposed work is intended to analyze the consumption and the cost of lubricants used in industrial maintenance sector of a company. The work is started with the employees responsible for the factory lubrication routine. From the interwiew with the employees, a survey of information and a database development was done. Indeed, the dadabase began to be filled by the mainteners themselves, being monitored weekly by the author. Based on the database, a quarterly report was prepared by the author and from the diagnosis, hypotheses were raised on the possible causes of high consumption of lubricants in certain machines, such as leaks in pipes and fittings, equipment failure, lubrication parameterization errors, among others. An action to resolve such assumptions was made before the next report was generated. With this, a lack of planning was evidenced regarding the stock of spare parts and also the lack of knowledge of the manuals of the manufacturers by some employees who have direct contact with the machines. In addition, in terms of costs, a survey was made of how acquisition costs were made and after tha a new report was made, this time considering inventory costs incurred, verifying a difference in relation to what was actually spent. Based on the results, it was possible to achieve all the proposed objectives for the work, such as verifying the truth of costs, noting which machines obtained the highest consumption of lubricants and the possible causes of equipment failure due to a lubrication failure.
