Abstract

Ce dispositif de détection d'abrasion destiné à un mécanisme de palier lisse dans lequel un arbre orbite le long de la surface circonférentielle interne d'un palier, le dispositif comprenant : un détecteur qui est fixé à l'arbre et/ou à une structure de palier qui comprend le palier, et qui détecte une valeur prédéterminée relative à l'orbite de l'arbre par rapport à la structure de palier ; et un dispositif de détermination qui détermine si une variation orbitale, estimée à partir de la valeur prédéterminée et par rapport à une orbite de référence prescrite, a dépassé une variation prédéterminée.
