ABSTRACT:
An arm/rotor hub assembly comprises a hollow rotor and a plurality of hollow arms, each of the arms passing through a corresponding aperture of the rotor sidewall and having one end thereof extending outwardly of the rotor in a generally transverse direction and the other end thereof disposed within the rotor and flared outwardly to a diameter greater than that of the corresponding aperture. The inner surface of the rotor sidewall defines a recess adjacent each of the apertures, and the rotor other ends have a portion thereof at least partially disposed within the recess adjacent the corresponding aperture. The assembly is put together by inserting the other arm ends through the corresponding apertures and employing a flaring tool inserted into the rotor through the open rotor end to flare the other arm ends outwardly within the rotor to a diameter greater than the apertures and force some portions of the other arm ends into the recesses and other portions intermediate the apertures and the open rotor end.
