Chapter 28: Rolling Element Bearings

Such features often put rolling element bearings on the top of the bearing selection list 28 2 Rolling Element Bearing Types Various means have been used to categorize rolling element bearings such as by the geometry of the rolling elements by the manner in which a bearing is used or by certain technical features that the bearing possesses

Deep Learning Enabled Fault Diagnosis Using Time

Fault diagnosis of rolling element bearing is a significant issue in industry Detecting faults early to plan maintenance is of great economic value Prior applications of deep learning based models tended to be limited by their sensitivity to experimental noise or their reliance on traditional feature extraction

Signal

The example Rolling Element Bearing Fault Diagnosis uses spectral features of fault data to compute a condition indicator that distinguishes two different fault states in a bearing system Time-Frequency Moments Time-frequency Run the command by entering it in the MATLAB Command Window

Generate frequency bands around the characteristic fault

For this example consider a ball bearing with a pitch diameter of 12 cm with 10 rolling elements Each rolling element has a diameter of 0 5 cm The outer race remains stationary as the inner race is driven at 25 Hz The contact angle of the ball is 0 degrees The dataset bearingData mat contains power spectral density (PSD) and its respective
