Optimised taper rolling bearings for wind turbines - …

Optimised taper rolling bearings for wind turbines. Schaeffler develops flange mounted bearings to support complex loads present in wind turbines. All the forces from the wind act directly on the rotor bearing in a wind turbine, which means the rolling bearings are subjected to high dynamic loads and harsh operating conditions.

bearings, driveshafts, and precision equipments - Products by Market:Wind Turbine…

Tapered roller bearings are designed so the inner and outer ring raceway and the apex of the tapered rollers intersect at one point on the bearing centerline. For this reason, the rollers are pushed against the inner ring rib and roll guided by the rib, receiving the loads from the inner ring raceway surface and the outer ring raceway surface as a coined load on the raceway surface.

Main bearings for wind turbines - Liebherr

Depending on the type of wind turbine, triple-row roller bearings or double-row tapered roller bearings are used as main bearings. While the roller bearing leads to lower stresses in the adjacent construction, the tapered roller bearing is particularly attractive because it has zero play, therefore allowing for an optimal rolling behaviour of the bearing.
