Diseño y construcción de un módulo para determinar la cantidad de grasa en elementos rotativos para el laboratorio de tribología de la Facultad de Mecánica.

Abstract

Currently, the Tribology Laboratory has a testing module for oils in which tests for fats cannot be carried out, which has generated some problems such that there is a need to have other equipment, whether educational or simulation of industrial processes and thus have the ease of developing various tests. The objective of this work was to design and build a module to determine the amount of grease; a set of gears and a pair of UC201-08 bearings were used, where the amount of lubricant is determined by three parameters: speed, load, and roughness of the material. Following the ISO 9241-210 STANDARD that uses the QFD method, it was developed that the primary purpose of an ergonomic study was to achieve an effective design of the work environment, guaranteeing its efficiency and safety and promoting the well-being of users. In addition, the ISO 15 standard for deep groove ball bearings was used, which developed the general design requirements, dimensions, tolerances, materials, tests, and test methods. The choice of lubricant depended on the bearing rotation speed, applied load, operating temperature, and maintenance frequency. Lubricants include high-quality mineral oils and greases. A module was designed and built for the Tribology Laboratory of the Mechanics Faculty for educational purposes. This module will determine the amount of grease in rotating elements, calculating the quality of each component used with reliability and safety. when carrying out the practices indicated in the laboratory guides. In addition, an operation and maintenance plan for the module was developed to achieve the physical asset's maintainability.
