Diseño y construcción de un equipo para ensayos de lubricación hidrodinámica para el laboratorio de tribología de la Universidad Politécnica Salesiana - Campus Kennedy

Abstract

The following project aims to design and build an educational equipment for hydrodynamic lubrication study, which will show the pressure distribution in a journal bearing by combining different loads and speeds on it. Values of pressure will be taken thanks to pressure tappings around the bearing. These values will be represented by the height of oil in manometric tubes due to hydrostatic pressure. Chapter 1 describes lubrication theory and types of lubrication. Hydrodynamic lubrication is very prominent in this chapter because the machine will study that specifical kind. In chapter 2, there is an alternatives analysis to choose the right design giving priority to the educational aspect, because the machine will be used for laboratory experimentation. In chapter 3, the design of the bearing is made based on the alternative chosen in the previous chapter. Also, the additional equipment that makes up the machine is selected. Calculations are performed based on the formulations of chapter 1 and optimal design parameters for the journal bearing. In chapter 4, there is an analysis of theoretical and experimental results using comparative dispersion graphs using different variables, to understand their effect over the phenomenon of hydrodynamic lubrication. In chapter 5, the costs of mechanical, electrical and electronic equipment are detailed. Also the cost of labor is shown. In Chapter 6 the labs that can be enhanced with the built equipment are shown Finally, conclusions, recommendations, list of references, guides for experiments and annexes are exposed.
