Benefits of technology
Enables immediate operator attention to potential issues, shortens data processing times, and lowers memory storage requirements, facilitating timely maintenance and reducing the risk of component failure.
Problems solved by technology
Rotating components such as bearings are often used in critical applications, wherein their failure in service would result in significant commercial loss to the end-user.
Fatigue failure of a rolling element bearing results from progressive flaking or pitting of the surfaces of the rolling elements and of the surfaces of the corresponding bearing races.
The flaking and pitting may cause seizure of one or more of the rolling elements, which in turn may generate excessive heat, pressure and friction.
However, this type of life prediction is considered inadequate for the purpose of maintenance planning for several reasons.
Another reason is that a bearing's residual life may be radically compromised by short-duration events or unplanned events, such as overloads, lubrication failures, installation errors, etc.
Yet another reason is that, even if nominal operating conditions are accurately reproduced in service, the inherently random character of the fatigue process may give rise to large statistical variations in the actual residual life of substantially identical bearings.
This can however result in long transmission and display times and the data can be difficult to display or interpret.
The transmission, display, storage and interpretation of such data can require a significant amount of energy, time and expertise, and consequently decreases the rate at which measurements and analyses can be made.
