Ball Bearing Vibration, and Temperature Run-to-Failure Dataset

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本数据集收录了球轴承从正常运行至最终失效全周期的振动与温度数据。试验阶段，轴承以1770转每分钟（Revolutions Per Minute, RPM）~1780转每分钟的恒定转速持续运转直至失效，运行策略为单次运转5分钟后停机休憩15分钟。当轴承温度突破85℃、振动幅值超过9 m/s²时，本次加速寿命试验终止。试验过程中，向受试球轴承施加了300 kg（2.94 kN）的轴向载荷与600 kg（5.88 kN）的垂直载荷。受存储容量限制，数据按小时间隔提取并公开发布。 ### 数据集详情 1. 数据文件按小时间隔打包存储，压缩包"Vibration_Bearing_RuntoFailure.zip"内共计129个逗号分隔值（Comma-Separated Values, CSV）文件。 2. 每份数据文件包含4列数据：x轴振动、y轴振动、轴承温度、环境温度。 3. 振动数据采样率为25.6 kHz，单条数据时长为78.125秒，所用振动传感器型号为PCB 352C34。 4. 温度数据采样率为25.6 kHz，单条数据时长为78.125秒，所用温度传感器为K型热电偶。 ### 试验基本参数 - 运行周期：2022年6月20日17:00 至 2022年6月26日01:00，总计128小时 - 旋转转速：1770 RPM ~ 1780 RPM - 轴向载荷：300 kg（2.94 kN） - 垂直载荷：600 kg（5.88 kN） ### 受试球轴承规格 - 型号：NSK 6205 球轴承（钢制密封型） - 内径：25 mm - 外径：52 mm - 宽度：15 mm - 保持架材质：钢制 - 最高允许转速：13000 RPM - 基本动额定载荷：1509 kg（14.8 kN） - 基本静额定载荷：795 kg（7.8 kN） 如需获取更多详细信息，可查阅期刊《Data in Brief》，链接：https://www.sciencedirect.com/journal/data-in-brief，对应文章标题：Vibration, and Temperature Run-to-Failure Dataset of Ball Bearing for Prognostics
