ABSTRACT:
A fastening system particularly suited for securing parts of a rotor of a slant axis rotary mechanism together including links (110) abutting each of the rotor parts (60, 62), and spanning the interface (ABCD) between the parts. Pivotal nut structures (108) are journalled in the ends of the links and linear passageways (90) are disposed in the rotor parts to be nominally aligned with the nut structures. The passageways are at an acute angle to the rotor axis and terminate in a shoulder (100) at their ends remote from the nut structures. Threaded, headed fasteners have their heads (98) in operative engagement with corresponding ones of the shoulders and extend through the passageways to be threadably received by the corresponding nut structures to tension the associated links and thereby hold the rotor parts in assembled relation.
