Estudio de la eficiencia y fenómenos disipativos de engranajes con correcciones de tallado y modificaciones del perfil

Abstract

In this Doctoral thesis, the features and capacities of the starting gear dynamic model, which was developed in the Mechanical Engineering Group of the University of Cantabria, have been extended. It has been studied the efficiency, under high loads, of gear transmissions with standard teeth, shifting profile and profile modifications such as tip relief. In these operating conditions, the most determinant dissipative phenomena on the efficiency is the sliding friction. In order to calculate the forces due to friction, an enhanced Coulomb’s model has been utilized. This model consist on the usage of enhanced formulations of load sharing and friction coefficient, which are dependent on the angular position.
