Abstract
Official abstract text for this publication.
A yaw or pitch bearing for a wind turbine includes a slewing ring bearing assembly having an outer race and an inner race, both having an inner surface and an outer surface. The inner surface of the outer race and the outer surface of the inner race have a plurality of threads that engage and define a threaded bearing surface.
First claim
Opening claim text (preview).
What is claimed is: 1. A slewing ring bearing assembly for a wind turbine yaw or pitch bearing, comprising: a ring-shaped outer race comprising opposing annular top and bottom surfaces, and an inner circumferential surface, the top surface of the outer race configured for attachment to at least one of a rotor blade, a hub, or a nacelle of the wind turbine, the inner circumferential surface of the outer race comprising a plurality of threads; a ring-shaped inner race comprising o…
