Abstract

Détecteur de coussinets échauffés. Pour effectuer la distinction entre des paliers à rouleaux et des paliers lisses dans un système détecteur de coussinets échauffés de wagons de chemins de fer, on explore, à l'aide d'un dispositif du type à infrarouge, les paliers du wagon. Le signal d'exploration est intégré sur une période et sur une fraction de période. Le rapport entre les signaux ainsi intégrés fournit une indication sur nature du palier exploré. Application : distinction entre paliers à rouleaux et paliers lisses.
