Description
Thomas Matthias Decker and co-authors validate a condition monitoring system for planetary journal bearings in wind turbine gearboxes, based on surface acoustic wave measures. Published in 2025, the work moves past small test rigs to a full system test on an 850 kilowatt gearbox. Such bearings enable compact, durable gearboxes, yet rare events like dirt in the oil can damage them fast.
No commercial monitoring system exists for these bearings, the authors note. Their sensor setup is described, then the load test campaign on the full gearbox. Finding critical states before damage starts would cut downtime and repair costs for turbine drive trains. The study tests whether the acoustic approach holds up at system scale.
