Case study: Condition assessment of non-inspectable turbine bearings

Sometimes bearings in wind-turbine gearboxes are not reachable with an endoscope probe. This is a common issue for specific gearbox models, where several bearings are partially or completely non-inspectable. It is caused by either the tight construction of the bearing itself or shaft elements, such as oil deflectors, which impede the access. But how does an
