Abstract

A rotor assembly for a wind turbine includes a rotor blade extending between a blade root and a blade tip, a rotatable hub, a pitch bearing arranged between the rotor blade and a hub of the wind turbine, and a stiffener ring. The pitch bearing has an outer race, an inner race rotatable relative to the outer race, and a plurality of roller elements arranged between the outer race and the inner race. The stiffener ring is arranged between one of the inner race or the outer race of the pitch bearing and the blade root. Further, the stiffener ring has a symmetrical shape so as to provide uniform stiffness to the pitch bearing so as to provide a uniform stiffness to the pitch bearing.
