Numerical characterization of local and global non-uniformities in the load distribution in ball screws
(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-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 ...
Load distribution and tooth root stress of highly crowned spherical gear couplings working at high misalignment angles
(Elsevier, 2023)
Spherical gear couplings are commonly used mechanical components to transmit power between highly misaligned rotating shafts. For that, gear couplings are manufactured with high longitudinal crowning and are usually small ...
Generación virtual de la geometría 3D de acoplamientos dentados abombados
(2021)
Los modelos analíticos, y cada vez más los numéricos, son herramientas utilizadas para el diseño y dimensionamiento tanto de engranajes como de acoplamientos dentados. Los resultados obtenidos, dependen de la exactitud de ...
The combined effect of contact interface size and spin on lubricated traction in rolling-sliding point contacts
(Elsevier, 2023)
Traction in lubricated rolling and sliding contacts plays an important role in the performance of several machine elements. Many of such elements are subject to spin motion, which can affect their performance. Recent studies ...
Non-destructive experimental technique to determine ball contact load in rolling machine elements
(Elsevier, 2024)
Rolling machine elements, such as ball bearings, ball screws, or guiding systems are commonly used in diverse industrial applications. These components typically assume uniform load distribution among the balls or rely on ...
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 ...
Análisis del efecto de shot-peening y el cementado en la vida a fatiga de los engranajes
(Sociedad Española de Integridad Estructural - Grupo Español de Fractura SEIE-GEF, 2023)
Debido a sus condiciones de trabajo, la fatiga es uno de los modos de fallo más comunes en los engranajes. A pesar de que habitualmente se emplean diversos tratamientos para mejorar las propiedades mecánicas de los mismos, ...
Modelizado bidimensional de engranajes cilíndricos por elementos finitos
(UNED, 2018)
El análisis de la distribución de carga, rigidez y error de transmisión de engranajes cilíndricos es fundamental para predecir los efectos de la geometría del dentado sobre las vibraciones, resistencia y eficiencia. El uso ...
Influence of thermal distortion on load distribution, transmission error and premature contact
(INSA, 2018)
The influence of thermally-induced geometry distortions on representative gear parameters such as load distribution or transmission error is analysed. An analytical load distribution model is coupled to a thermal ...
