Análisis de distribución de carga en husillos a bolas para altas cargas mediante modelos de elementos finitos optimizados

Sangalli, Luca; Oyanguren , Aitor; Larrañaga Amilibia, Jon; Ulacia, Ibai (2023)

Los husillos a bolas son actuadores electro-mecánicos ampliamente utilizados en máquinas y mecanismos como solución de posicionamiento lineal, caracterizándose por su gran rigidez y capacidad de carga. Estos sistemas han ...
Numerical characterization of local and global non-uniformities in the load distribution in ball screws

Sangalli, Luca; Oyanguren , Aitor; Larrañaga Amilibia, Jon; Arana, Aitor; Izquierdo Ortiz de Landaluce, Mikel; Ulacia, Ibai (Springer, 2021)

Load distribution in ball screws is a representation of the ball contact stress, and it is fundamental to understanding the behavior of these machine elements. This work aims to conduct a multi-variable analysis of the ...
Numerical study on the effectiveness of the optimization of the load distribution in ball screw actuators

Sangalli, Luca; Oyanguren , Aitor; Larrañaga Amilibia, Jon; Izquierdo Ortiz de Landaluce, Mikel; Ulacia, Ibai (Elsevier, 2024)

Load distribution in ball screws is characterized by non-uniformity, leading to imbalances in the contact load of the balls along the nut. This non-uniformity negatively impacts the stiffness, accuracy and service life of ...
