Abstract

L'invention décrit un procédé de surveillance de l'état de trains d'engrenages (10) épicycloïdaux de relais d'accessoires ou de réducteurs de vitesse de moteurs d'aéronefs, comprenant une étape de mesure en continu pendant la rotation du train d'engrenages (10) d'une résistance électrique entre au moins une paire d'éléments conducteurs du train d'engrenages (10), et une étape de détermination, par analyse de la résistance électrique mesurée, d'au moins une information relative à la qualité de contact des éléments conducteurs situés entre les points de mesure. L'invention concerne également un produit programme d'ordinateur comprenant des instructions de code pour l'exécution d'un tel procédé, et un dispositif de surveillance de l'état de trains épicycloïdaux (10) adapté pour mettre en œuvre ce procédé.
