Determinação do carregamento dinâmico em mancais de esfera de contato angular

TL;DRAbstract

The bearings are of great importance and its major function is to support a rotating element.Due to the mandatory role of these components in the interface between fixed and rotating elements, the bearings are the source of a great percentage of the possible faults on a system.The rolling bearings of angular contact are one of the most utilized, mainly by the automotive industry.In spite of the great applications field, these bearings are usually subject to damage by superficial fatigue, which makes of great significance the detailed study of the efforts and the velocities on the spheres and, consequently, on the external and internal railways.The description of the efforts and velocities acting on the spheres is a considerable challenge, once the spheres are subject to an elastohidrodynamic lubrication that fully depends on the efforts and velocities of the spheres, generating an iterative process.The main objective of this work is to analyze the rolling bearings of angular contact, u
