Accelerometric measurements from the rolling bearing test rig of the Dynamic and Identification Research Group(DIRG),Department of Mechanical and Aerospace Engineering, Politecnico di Torino. Goals: Vibration Monitoring, Bearing Diagnostics,Damage detection,Damagelocalization, Damage classification, Damage assessment. Features: high-speed spindle drivinga hollow shaft supported by a couple of identical roller bearings B1 and B3. B1 is the bearing under analysis and features various damages. two damage types (indentations on a roller and on the inner ring) and severities (0, 150, 250, 450 m). acentral, larger roller bearing (B2) is loaded through a sledge generating a controlledradial force measured by a load cell. lubrication is obtained by oil injectioninto the hollow shaft. a K-type thermocouple is used to monitor the temperature (manually recorded). two triaxial accelerometers are mounted on the supports of bearings B1 and B2. Dataset: stationary acquisitions at different speed load combinations (speed: 0, 100, 200, 300, 400, 500 Hz;load: 0, 1000, 1400, 1800 N). endurance acquisitions of the bearing featuring the 450m roller indentation. Monitoring of the damage evolutionfor about230hoursunder the same speed and load condition.
