A method for solving load distribution over outer, inner raceways and ribs was developed. It is especially suitable for the load conditions and geometrical characters of huge double row tapered roller main bearings in wind turbines.Based on the method, contact load of rollers acting on raceways and ribs can be calculated, which can be provided as a reference for optimizing the bearing carrying capacity and geometrical parameters. Bearing static capacity under extreme loads was checked combined with the actual engineering design.
