Comportamiento Tribológico de las Ruedas y Rieles de los Ferrocarriles Sometidos a Recargue por Soldadura Eléctrica en la Empresa Ferrocarriles del Ecuador.

Abstract

In the following thesis, a research about tribological work of railways wheels and rails in the company “Ferrocarriles del Ecuador” (FEEP) was carried out in real exploitation conditions and with help of laboratory trials, an analysis in the process used in the company workshops in Riobamba was carried out to increase the wheel utility in the railways at FEEP. It was determined that the processes used by the company for wheel recovery were carried out in an empirical way, without any previous study of basic and support material, or work system the wheels are under. A valid alternative is presented from the wheel-rail pair tribological viewpoint for wheel recovery, base on the wear trial to which the wheels were under. With the support material proposed, both, costs and wheel recovery time were reduced, as well as improving reliability and work of railway wheels. The wheel recovery method which was proposed is tested according to effort and properties that rails and wheels are under from the mechanical viewpoint, with help of methods and processes carried out by authors. Finally the conclusions and recommendations established in the research must be taken into account to get better result in wheel recovery process in FEEP.
