The present work aimed at the modernization of the rubber wheel abrasion tester, being that this apparatus is present in the LTM for academic and researching purposes in tribology, specifically in the severity of the abrasive wear. The motivation of this work was the change in the way the test was operated, from the vertical to horizontal positioning of the sample. Structural changes have been made in the present mechanism in order to comply with the ideas presented in this paper, but without going beyond the standard ASTM G-65, which governs this experiment. In addition, an abrasive collection system was designed so that particles used in the process could be analyzed for the severity of the test on the abrasive itself, and unused particles that were previously discarded could be used in a new experiment. Both the old apparatus and the new one were designed with their proper dimensions in the SolidWorks software, thus obtaining maximum detail of the project. Finally, it is possible to verify the economic viability of the new test, both in operational matters and in material expenses.
