Geometrical accuracy improvement in flexible roll forming process by means of local heating
Larrañaga Amilibia, Jon (Mondragon Unibertsitatea. Goi Eskola Politeknikoa, 2011)In the last decade the tendency to reduce vehicle weight due to rising fuel prices and environmental requirements, have pushed two main trends of research in the field of vehicle structure manufacturing. On the one hand, ... -
Geometry optimisation of highly crowned gear couplings working in high misalignment applications to reduce tooth root stresses
Iñurritegui-Marroquin, Aurea; Larrañaga Amilibia, Jon; Arana, Aitor; Ulacia, Ibai (EDP Sciences, 2023)Crowned gear couplings are mechanical components used to transmit power between misaligned rotating shafts. Their geometry is characterised by a significant longitudinal crowning to accommodate angular misalignment. Recent ... -
Influence of the velocity on quasi-static deflections of industrial articulated robots
Aguirre Jaca, Nora; Larrañaga Amilibia, Jon (Springer, 2023)This article presents the measurement and analysis of the influence of velocity on the quasi-static deflections of industrial manipulators of three different manufacturers. Quasi-static deflection refers to the deflection ... -
Load distribution and tooth root stress of highly crowned spherical gear couplings working at high misalignment angles
Iñurritegui-Marroquin, Aurea; Larrañaga Amilibia, Jon; Arana, Aitor; Ulacia, Ibai (Elsevier, 2023)Spherical gear couplings are commonly used mechanical components to transmit power between highly misaligned rotating shafts.
