Abstract
A spherical outer diameter tapered roller bearing pillow block system () for supporting the rotating main shaft of a wind turbine. The bearing system is configured with a unitized construction and factory set preload bearing settings to facilitate installation and setup. A spherical outer diameter surface () is formed on the outer race () of a tapered roller bearing assembly disposed about the rotating main shaft of the wind turbine. The bearing assembly is secured to a stationary support structure of the wind turbine through a pillow block housing assembly () providing a matching spherical housing seat () to form a ball and socket interface between the tapered roller bearing assembly () and the pillow block housing assembly (). The ball and socket interface accommodates static and dynamic misalignments between the wind turbine main shaft and the supporting structure, while the bearing assembly () accommodates radial and axial loads.
