Opening the Envelope on Bearing Vibration - September 2016

Chris Hansford, Managing Director, Hansford Sensors

The article "Opening the Envelope on Bearing Vibration" appeared in the September 2016 issue of Power Transmission Engineering.

Summary
Experienced operators can often tell if a machine is not working properly, on the basis that it does not ‘sound right.’ The same principle can be applied — using modern electronics — to identify the exact cause of the problem. Sensitive accelerometers can detect and analyze the vibrations from industrial equipment, highlighting problems such as misalignment or bearing imbalance. The technique is known as vibration analysis. It can identify bearing failure in the very early stages, when there is a microscopic defect on the raceway, for example. The problem is that the identifying signal is usually drowned out in all the other noise emanating from the machine.
