Most wind turbines use gearboxes to transform the relatively low rotational speed of the main shaft into the higher speeds required for power generation. Single or two stage planetary gears are often used to keep the overall size small. The bearings of the planetary gears tend to be highly loaded in this application. Austrian bearing […]
