Tensiones en el pie de acoplamientos dentados abombados que trabajan en aplicaciones con alta desalineación
(2023)
Los acoplamientos dentados abombados son componentes mecánicos para transmitir potencia entre ejes en rotación desalineados. Para poder absorber dichas desalineaciones y en especial, la desalineación angular, la geometría ...
Evolución de la fatiga superficial en engranajes de acero al carbono
(2023)
Los engranajes rectos de aceros de bajo contenido de carbono se utilizan ampliamente en aplicaciones de baja exigencia debido a su bajo costo y simplicidad de fabricación. Uno de los fallos más comunes de estos engranajes ...
Análisis de distribución de carga en husillos a bolas para altas cargas mediante modelos de elementos finitos optimizados
(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-experimental analysis of highly crowned spherical gear couplings working at high misalignment angles
(Elsevier, 2023)
Spherical gear couplings are characterized by their high capacity to transfer power between rotating shafts in highly misaligned conditions. They are usually small because of space restrictions and require a high amount ...
Geometry optimisation of highly crowned gear couplings working in high misalignment applications to reduce tooth root stresses
(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 ...
Theoretical analysis of transmission error in rack and pinion systems
(EDP Sciences, 2023)
Rack and pinion drive systems are widely used in machine tools with long travel distances because the stiffness is independent of the travelled distance, in contrast to other drive systems such as ballscrews. Although the ...
Optimization of the semi-hexagonal geometry of a composite crush structure by finite element analysis
(Elsevier, 2016)
In the present paper a numerical model for predicting the crushing behaviour of semi-hexagonal E-glass/polyester composite structures has been developed. Qualitative and quantitative analysis have shown that the results ...
Numerical Fretting© Wear Simulation of Deep Groove Ball Bearing Under Radial Variable Load
(Springer, 2022)
Bearing has become one of the most widely used mechanical components over the world. Even this component has been extensively studied, there exist especial applications or untypical operating conditions that still must be ...
Aumento de la precisión de posicionado de células robóticas en aplicaciones de mecanizado
(2023)
En las últimas décadas han incrementado las aplicaciones de los robots industriales aumentando también la demanda en la precisión de posicionado. Sin embargo, los robots industriales se caracterizan por ser muy repetitivos ...
A general kinematic model for lubricated ball bearings based on the minimum energy hypothesis
(Elsevier, 2024)
Accurately predicting the performance of lubricated rolling elements is critical for certain key bearing applications. A widely employed simulation technique is quasi-static models, which although computationally efficient ...
