  • What bearings are used in wind turbines? - Insight -

    2020-3-23 · The gearbox of a wind turbine is often subjected to high speeds, as well as challenging atmospheric conditions. There are numerous different bearing designs that can be found in the gearbox of a wind turbine, but generally a combination of cylindrical roller bearings, tapered roller bearings and ball bearings are used, depending on the speed ...

    2014-8-26 · The horizontal-axis wind turbine was invented in Egypt and Greece around 300 BC. It had 8 to 10 wooden beams rigged with sails, and a rotor which turned perpendicular to the wind direction. This type of wind turbine later became popular in Portugal and Greece. Around 1200 AD, the crusaders built and developed the post-mill for milling grain.
