Ultra high efficiency low friction drive chain for wind turbine applications

摘要

A low friction joint apparatus for chain links is provided. The apparatus may include a first link pin rigidly coupled to a first chain link, a second link pin rigidly coupled to a second chain link, a sprocket roller coaxially and pivotally disposed about the second link pin, a plurality of radial bearings radially disposed between the second link pin and each of the first link pin and the sprocket roller, and a plurality of axial bearings axially disposed between the second link pin and the first chain link, and between the sprocket roller and the second chain link. The second link pin may be coaxially and pivotally disposed about the first link pin. The sprocket roller may be rotatable relative to each of the first and second chain links.
