optimum mechanical designgenetic algorithmsThe design of rolling element bearings has been a challenging task in the field of mechanical engineering. While most of the real aspects of the design are never disclosed by bearing manufacturers, the common engineer is left with no other alternative than ...
The problem of the rolling element bearing was optimized previously using GA4 [54], ABC, and TLBO. Table 18 shows the comparison of the best solutions for the three optimizers and the proposed method in terms of design variables and function values, and constraints accuracy. Show abstract ...

Device for sealing and mounting a rolling-element bearing A device for sealing and/or mounting a rolling-element bearing in a housing or on a shaft includes a sheet-metal disk secured to one of the bearing rings and an annular portion which interfaces with the other ring to form a seal. ...
Advanced Diagnostic and Prognostic Techniques for Rolling Element Bearings Bearing failure is one of the foremost causes of breakdown in rotating machine, resulting in costly systems downtime. This chapter presents an overview of current state-of-the-art monitoring approaches for rolling element bearings...
This tutorial is intended to guide the reader in the diagnostic analysis of acceleration signals from rolling element bearings, in particular in the presence of strong masking signals from other machine components such as gears. Rather than being a review of all the current literature on bearing di...
This example shows how to perform fault diagnosis of a rolling element bearing using a deep learning approach. The example demonstrates how to classify bearing faults by converting 1-D bearing vibration signals to 2-D images of scalograms and applying transfer learning using a pretrained network...
