Modelado 3D CAD de la distribución de vapor de la máquina escocesa Mirrlees-Watson (1926) para extracción de azúcar de caña.

Abstract

The interest of this work lies in the application of 3D modeling aimed at the conservation of Industrial Heritage. The present communication addresses the three-dimensional digital reconstruction parameterized by means of mechanical CAD / CAM, as an industrial design tool for manufacturing, of the Corliss type steam flow distribution system of the Mirrlees-Watson Scottish technology steam engine (1926), located in the Azucarera Ntra. Sra. del Rosario, in Salobreña (Granada) destined to generate the mechanical energy necessary to drive a continuous train of sugarcane milling. The Corliss distribution consists of four suspended connecting rods, actuated by means of a centered oscillating disc, moved by a rocker articulated to the arm of an eccentric draft in the distribution shaft, acting on four valves and these, on four cylindrical slides, two for the admission of steam at its entrance to the cylinder, positioned in its upper generatrix and two others for exhaust, in the lower generatrix. This study will show a CAD modeling with Autodesk Inventor Professional software, whose visual recreation will be done by exporting to Autodesk 3ds Max Design, applying Vray Physical Camera cameras, standard and photometric lighting with Vray rendering engines and digital postproduction..
