This thesis is dedicated to the study of large-size spinning contacts located at the interface between the roller-end and the flange in rolling-element bearings. The main goal of the study is to evaluate the influence of lubricant starvation on the f

The current environmental context is driving the aeronautic industry towards new design criteria. On the one hand, governments demand emission reductions of pollutants and on the other hand, customers, i.e. aircraft manufacturers, are pushing to redu

Surface fatigue is currently the main cause of rolling element bearings failures. This type of fatigue can appear due to the presence of surface asperities but is exacerbated by the presence of surface defects such as dents. Handling the contaminatio

Highly loaded lubricated contacts are often studied in rolling/sliding conditions. In those cases, the entrainment of lubricant in a so-called “oil wedge” explains the existence of a separating film thickness. However, in a number of industrial a

La plupart des montres mécaniques sont composées d’un échappement à ancre Suisse. Cet organe se situe à la fin du rouage et sert à entretenir et à compter les oscillations du balancier-spiral. Par l’intermédiaire de l’interface ancre /

L’étude du frottement dans les contacts lubrifiés fortement chargés est un sujet complexe. En effet, le frottement dépend fortement du comportement rhéologique du lubrifiant dans le centre du contact et, celui-ci n'est pas bien connu à pressi

Une lubrification suffisante est essentielle au bon fonctionnement des mécanismes et/ou composants comme par exemple les paliers à roulement. Par contre, les lubrifiants contiennent souvent des débris d’usure ou des polluants extérieurs. Ces pa

Contact lubrication is essential in a wide range of mechanical systems like rolling element bearings (REBs). A minimum quantity of clean lubricant all along the bearing life is necessary but difficult to ensure. In fact, lubricants contain inevitably
