Rolling Bearing Dataset

This rolling bearing dataset was collected using the QPZZ-II rotating machinery fault simulation test rig developed by Jiangsu Qianpeng Diagnostic Engineering Co., Ltd. The bearing used in the experiment was model NU205EM. An electromyographic-type acceleration sensor was used in this experiment, which was placed in the horizontal X and vertical Y directions of the bearing housing on the test rig. Under the conditions of a rotational speed of 1200 r/min and a sampling frequency of 5120 Hz, normal state (Norm), inner ring fault (IRF1, IRF2), rolling body fault (BF1, BF2), and outer ring fault (ORF1, ORF2) were collected.

本滚动轴承数据集采用江苏谦鹏诊断工程有限公司研发的QPZZ-II型旋转机械故障模拟试验台采集所得。实验所用轴承型号为NU205EM。本次实验采用肌电式加速度传感器，将其分别布置于试验台轴承座的水平X向与垂直Y向。在转速1200 r/min、采样频率5120 Hz的工况下，采集了正常状态（Normal State，缩写Norm）、内圈故障（Inner Ring Fault，IRF1、IRF2）、滚动体故障（Rolling Body Fault，BF1、BF2）及外圈故障（Outer Ring Fault，ORF1、ORF2）共7类工况的振动数据。
