Description

This data includes vibration data according to the time from when the bearing is normal to when it is failed. The bearing was rotated at a constant speed of 1770 RPM ~ 1780 RPM until bearing failure (operated for 5 minutes, and operated for 15 minutes with rest). The accelerated bearing life test was terminated when the bearing temperature exceeded 85 °C (Celsius) and the vibration value exceeded 9 m/s^2. For the accelerated life test, an axial load of 300 kg (2.94 kN) and a vertical load of 600 kg (5.88 kN) were applied to the ball bearing. Due to capacity issues, data were extracted and published at hourly intervals. * Descriptions of the dataset - Data files are organized in hourly intervals (129 CSV files in "Vibration_Bearing_RuntoFailure.zip"). - Each data file consists of 4 columns ("vibration (x-axis)", "vibration (y-axis)", "temperature (bearing)", "temperature (Atmospheric)"). - Vibration data are acquired at a sampling rate of 25.6 kHz, and the data length is 78.125 seconds (vibration sensor model: PCB 352C34). - Temperature data are acquired at a sampling rate of 25.6 kHz, and the data length is 78.125 seconds (temperature sensor model: Thermocouple K-Type). * Details about the experiment Operating period: 2022.06.20 17:00 ~ 2022.06.26 01:00 (128 hours) Rotating speed: 1770 RPM ~ 1780 RPM Axial load of 300 kg: (2.94 kN) Vertical load of 600 kg: (5.88 kN) * Ball Bearing specifications Model: NSK 6205 Ball Bearing (steel-sealing) Inside diameter: 25mm Outside diameter: 52 mm Width: 15 mm Cage type: Steel Maximum Rotational Speed: 13000 RPM Basic dynamic load rating: 1509 kg (14.8 kN) Basic static load rating: 795 kg (7.8 kN) For more information, please check it via 'Data in Brief'. site: https://www.sciencedirect.com/journal/data-in-brief title: Vibration, and Temperature Run-to-Failure Dataset of Ball Bearing for Prognostics
