摘要

The assembly has a central laminated reel (12) arranged inside a hub (1), and a rotor mast comprising two interdependent plates. A laminated thrust ball joint (5) is arranged between the interdependent plates, and rotor blades (3) are fixed with a sleeve (4) on a reinforcement part (5') using a set of screws or bolts (11). The central laminated reel comprises laminated sectors (6'') that are connected together by plain bearings (8) and another set of screws or bolts (9). A cover (7) assembles the central laminated reel and pierced with a hole (7').
