The present invention. is for a system (11) or method for conditioned based monitoring of a bearing assembly. The system (11) comprises a sensor (13) placed in proximity to a bearing assembly (12). The sensor (13) generates a signal indicative of the amplitude and frequency of the vibrational movement of the bearing assembly. A process (14) in communication with the sensor (13) receives the signal from the sensor (13) and generates spectral data representative of the bearing vibrational movement. A database (15) comprises data representative of an amplitude threshold, for at least one predetermined frequency, characteristic of a bearing fault. The processor (15) compares the spectral data to the amplitude threshold and generates a signal indication of the bearing assembly.
Système (11) ou méthode de surveillance de l'état d'un montage à roulement. Le système (11) comprend un capteur (13) placé à proximité d'un montage à roulement (12). Le capteur (13) génère un signal indiquant l'amplitude et la fréquence du mouvement vibratoire du montage à roulement. Un processeur (14) en communication avec le capteur (13) reçoit le signal de ce capteur (13) et génère des données spectrales représentatives du mouvement vibratoire du palier. Une base de données (15) comprend des données représentatives du seuil d'amplitude d'au moins une fréquence prédéterminée, caractéristique d'une défaillance de palier. Le processeur (15) compare les données spectrales au seuil d'amplitude et génère un signal indicatif concernant le montage à roulement.
