Abstract

L'invention concerne un roulement comprenant au moins un système de détermination de l'amplitude A des déformations pseudo sinusoïdales d'une zone (7) de la bague fixe (1) qui sont induites lors de la rotation, le système de détermination comprenant deux jauges de contraintes (8), un dispositif de mesure (9) de deux signaux Vi qui sont fonction respectivement des variations temporelles du signal émis par chaque jauge (8) lors de la rotation, ledit dispositif étant apte à former, par combinaison des signaux Vi, deux signaux respectivement SIN et COS de même angle et de même amplitude, ladite amplitude étant fonction de A, et un dispositif de calcul (10) de l'amplitude A des déformations de la zone (7) en fonction du temps, ledit dispositif étant agencé pour calculer l'expression SIN2 + COS2 de sorte à en déduire l'amplitude A.
