How large offshore wind turbines are challenging bearing designs …

23/2/2018· The first is a two-point suspension with a toroidal roller bearing on the rotor side and a spherical roller bearing on the generator side. This is used for turbines in the 6-MW egory for example. For higher performance classes, the trend is to use ‘rigid’ bearing arrangement that features a non-loing and loing bearing coining a cylindrical roller bearing and a …

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.

Spherical roller bearings for wind turbine main shafts | SKF

Spherical roller bearings designed for wind turbine main shafts. The main shaft of a wind turbine must withstand some of the highest forces of any mechanical device. With turbines getting ever larger, this is only likely to increase. Few industrial machines are subject to the variable direction and thrust loads as seen in wind turbine main shafts.

Rolling Bearings enhance wind turbine rotor shaft performance…

7/4/2011· Spherical roller bearings are able to compensate for any angular misalignment of the shaft and support the high radial and axial loads that occur in wind turbines. However, the design of spherical roller bearings is such that relatively high radial internal clearance acts on the loing bearing side. This results in high axial internal
