Webinar Description: 
Case study on detecting and diagnosing gearbox bearing looseness on a wind turbine drive train.

Learning Takeaways:
• What are specialized filtered measurements (e.g. shaft running speed orders, high-frequency crest factor, tooth meshing frequency, and sideband energy level), and why they are needed to detect bearing looseness early
• Which diagnostics expertise is needed to distinguish between bearing faults and bearing looseness
• Why the gearbox shaft is of importance
• What happens if excessive clearance is not detected in time
• How to avoid catastrophic failures in the future and how to implement more pro-active monitoring strategies
