The challenge
On a critical belt conveyor, a lubrication defect generated abnormal friction at the heart of the reducer, prematurely wearing the gears due to metal-to-metal contact.. Completely invisible and inaudible during routine inspections, this gradual degradation inevitably led the equipment to complete mechanical failure..

The approach
Thanks to the continuous analysis of electrical signals, the RED system isolated an abnormal increase in the amplitude of the frequencies associated with the output of the reducer and its harmonics.. By tracking the evolution of these signatures, the algorithms revealed a mechanical drift over several weeks, triggering an alert well before the critical threshold was reached..

The result
A simple planned maintenance intervention to replace the oil was enough to stop the friction completely and save the equipment.. This anticipation enabled the prevention of a disastrous production stoppage of 80 hours (no spare reducers were available in stock), thus avoiding a total financial loss estimated at €129,500..
