What is a main bearing for a wind turbine?

the Creative Commons Attribution 4.0 License. This paper presents a review of existing theory and practice relating to main bearings for wind turbines. The main bearing performs the critical role of supporting the turbine rotor, with replacements typically requiring its complete removal.

What is a bearing failure in a wind turbine?

Bearing failures in wind turbines are a major cause of downtime in energy production for unplanned maintenance, repairs and replacements. This failure type is a primary cost and results in higher operations and maintenance (O&M) costs for the energy operator and in higher utility bills for the customer.

What are the operating conditions and loading of wind turbine main bearings?

The operational conditions and loading for wind turbine main bearings deviate significantly from those of more conventional power plants and other bearings present in the wind turbine power train, i.e. those in the gearbox and generator.

How many bearings are in a wind turbine?

A typical wind turbine consists of more than a dozen bearings that are expected to work simultaneously and continuously for many years. As a result, wind turbine bearings and gearboxes are often susceptible to failure well before their designed service lives.

Why do wind turbine bearings have a unique design?

Moreover, the bearing’s unique design prevents roller-to-raceway contact stress peaks from developing as a result of the periodic bending of the rotor shaft during operation or accuracy errors that arise from the initial assembly inside the wind turbine’s nacelle.
