Condition monitoring pinpoints the exact cause of gearbox vibration
Condition-based monitoring is a proactive maintenance health check for all types of electromechanical equipment and is crucial for identifying underlying system performance issues without stopping production.
Avonmouth Engineering Services (AES) provided this service to an aerospace company, Leonardo, to help investigate a loud noise generated by a lathe gearbox.
The lathe is a critical item in the plant as it is the first step in the gear machining process. The cost to purchase a new machine would have exceeded £100,000 and would also have led to a loss of production caused by downtime while a new lathe was installed.
AES carried out a detailed vibration analysis on the equipment. This is a nonintrusive method that can be used to detect obscure faults such as unbalance, resonance, misalignment or bearing failure. Combining the results with the technical drawings – which outlined the number, location and specification of the gears and bearings in the gearbox – AES was able to pinpoint that the exact cause of the excessive vibration came from a single bearing. Leonardo carried out the bearing change and have confirmed that the machine is now running without issue.

As we hurtle towards the end of
another turbulent year, energy
costs and the Chancellor’s
new ‘mini-budget’ are at the
forefront of our minds this quarter. The
repair and maintenance industry is perfectly
positioned to help navigate the energy crisis.
Meanwhile, there may be some benefits to
take from the mini-budget, too, although we
are yet to see what the full plan is.
