Cover Story (view full-size image): An ultrasonic method was developed to detect lubricant on rolling bearing raceways. It has been implemented both in the lab and an operating wind turbine. Sensors were mounted outside the raceway and sound waves reflected from the inner face. The ratio of reflected ultrasound to transmitted (reflection coefficient, R) was used to infer the raceway interface condition. Recurring reflection coefficient patterns between roller passes were used to identify the bearing lubrication condition. For the field measurements, three bearing lubrication conditions (partial, insufficient, and fully lubricated) were observed. The former two were found to occur mostly during transient operation.
