Premature Bearing Failures: The Achilles Heel Of Gearboxes .

Premature Bearing Failures: The Achilles Heel Of Gearboxes By Harpal Singh. Wind turbine gearboxes are designed to last 20 years. However, wind operators often experience gearbox failure rates of up to 50% across the lifetime of their fleets. If component fatigue, fretting or wear is caught early enough, an operator can mitigate consequential ...
