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 ...
Influence of thermal distortion on spur gear tooth contact
(American Gear Manufacturers Association (AGMA), 2018)
The reduction of component size and oil volume of current automotive and aeronautical transmissions along with the increasing input speed are pushing gear teeth bulk temperatures to their scuffing limit. Although new ...
Fatigue life prediction of spherical gear couplings
(American Gear Manufacturers Association (AGMA), 2018)
Spherical gear couplings are mechanical components that allow transmitting torque between misaligned shafts by means of equally spaced teeth. For instance, they are used in roll-levelling machines in order to transmit power ...
Fatigue and wear in crowned spline couplings
(Institute of Physics Publishing (IOP), 2018)
Prediction of the maximum tooth root stress for fatigue analysis of highly crowned spherical gear couplings working at high misaligned conditions
(Elsevier, 2024)
Spherical gear couplings efficiently transfer power between highly misaligned rotating shafts, featuring high longitudinal crowning in their design. At high misalignment angles, the contact point shifts across the face ...
