Slewing bearings – in the service of wind energy

To illustrate the forces acting on slewing bearings in wind turbines, let’s take a look at the rotor bearings at the base of the rotor blades. An onshore turbine with three rotor blades, each 63 meters long and weighing 20 tons, generates an energy output of 6.1 megawatts per hour at a wind speed of 14 meters per second.

However, a small wind turbine main shaft bearing runs at a speed of 60 RPM, and larger turbine shafts rotate even more slowly. Also, the temperature inside the nacelle rarely, if ever, exceeds 80 C. The maximum base oil viscosity that is appropriate for an FE9 test is ISO VG 220, Fish says, but most wind turbines require ISO VG 460 main greases to support the large …
