Abstract

A one piece fan blade for a wind machine is sandwiched between a hub and a plate. A rotatable shaft penetrably engages a bore extending through the plate, the fan blade and the hub and is secured thereto by a teeter pin extending through the bore from opposed passageways in the hub. The shaft is centered radially inwardly in the bore of the hub between opposed journals extending radially inwardly into the bore from the opposed passageways to permit tilting of the hub about an axis coincident with the teeter pin to an angle commensurate with the spacing intermediate the shaft and the bore.
