Bearing Analysis
Web Workshop #2: Early Detection of Lubrication Problems and Stage One
Bearing Faults by Jason Tranter, Mobius Institute
In part two of our four part web
workshop we will focus on the vibration monitoring techniques that focus
on the earliest stage of bearing faults and poor lubrication. Certain
analyzers and hand-held meters are able to detect faults at this early
stage; if they are used correctly. We will demonstrate that during stage
one, very low amplitude, short duration, high frequency vibration is
generated. This vibration is known as called ‘stress waves’ or ‘shock
pulses’. With the correct testing strategy these conditions can be
detected. The nature of the damage and vibration will be discussed, and
the optimum testing strategy will be discussed. Techniques such as
acoustic emission (airborne ultrasound), shock pulse, spike energy and
PeakVue will be reviewed.
