Monitoreo de la degradación de un aceite lubricante GEARBOX 320 en un motorreductor

Abstract

The objective of the present investigation was to monitor the Extreme Pressure Gearbox 320 mineral oil, in a gear reduction box. The interpretation of the oil analysis was carried out using the SACODE methodology, which includes a study of the health, contamination and degradation of the lubricant. Therefore, the following phases were used: first phase, the characterization and formulation of the new oil was obtained and in the second, the degradation was determined based on the time of use, and the implementation of a lubrication program. 7 samples were studied, 6 of these were used oil and 1 virgin oil, with which properties were obtained such as: viscosity, dielectric, total acids, oil formulation and ISO cleaning code, as well as additives, contamination elements and wear through an elemental analysis, the condemnatory limits of each variable were determined through numerical, percentage and statistical values. For the degradation analysis, graphs were used with the limits calculated by using the baseline as a reference for the new oil and the behavior of each variable, resulting in the guessing elements being below the critical limit. It is concluded that the oil maintains its properties except for guessing and the number of total acids, for which it does not meet the minimum operating characteristics. It is recommended to change the lubricant and take samples more frequently.
