ENGENHARIA DE MANUTENÇÃO APLICADA NO DIMENSIONAMENTO DA LUBRIFICAÇÃO DE MÁQUINAS UTILIZADAS POR INDÚSTRIAS ALIMENTÍCIAS DE NUTRIÇÃO ANIMAL

Abstract

The food manufacturing industries are machines that transform raw materials into finished or semi-finished products, most of these machines rotate grease-lubricated bearings. Although lubrication is of utmost importance to ensure the full functioning of equipment, many companies simply because they are unaware of the benefits that can be gained from properly lubricating assets tend to neglect this form of maintenance. This work consists of applying sizing methodologies and maintenance management to monitor the results obtained through the lubrication activities in bearings that make up machinery used in animal feed manufacturing. Based on manufacturers' manuals and technical literature, procedures are developed that can parameterize the administration of grease in rolling elements, allowing to adapt the most suitable amounts and relubrication periodicity for each equipment. The use of the methodology was started in January 2018 and the cause analyzes were based on data obtained between January and September 2018 and 2019. After the mentioned period there were indifferent results in the indicator of types of maintenance performed, but were achieved. better machine availability rates with an average monthly increase of up to 27.30% in the average time between failures, the biggest benefit being the reduction in lost profit. With regard to the maintenance of the bearing stock, there was also an average decrease of 22.56% of monthly revenue for the purchase of stock bearings. In the meantime, systematized and organized lubrication can increase the performance of industrial production and help reduce costs in the final product.
