Abstract
A hub assembly for an articulated rotor system mounted on a rotor shaft comprises three plates centrally secured to the rotor shaft. The plates include generally radially disposed and axially spaced apart upper and lower plates and a cone shaped pan plate. The upper plate and pan plate have outer marginal portions transversely connected in adjacent relation and central portions connected to the rotor shaft in axially spaced apart relation. The upper plate and pan plate cooperate with the rotor shaft to form a truss for supporting blade retention assemblies equally spaced about the rotor shaft axis and mounted intermediate the upper and lower plates. One of the plates has a scalloped central aperture which cooperates with the scalloped mounting flange on the rotor shaft to facilitate angular orientation for bolt alignment during hub assembly installation.
