Claims14
A rotor provided with a hub and a plurality of lift assemblies, each lift assembly having a retention and mobility member connected to an arm of the hub in order to hinge the lift assembly to the hub, the rotor having one abutment mechanism per lift assembly in order to protect the hub in the event of lead/lag movement of the lift assembly, the arm having an end provided with a top face and a bottom face that are connected together by an edge face facing a lift assembly, wherein each abutment mechanism of a lift assembly comprises:
- an elastomer spacer strip having a central section extending transversely from a first base to a second base along the edge face, each base having a central segment secured to the central section, the central segment of each base being arranged against the edge face and extending in elevation from a bottom longitudinal projection arranged against the bottom face to a top longitudinal projection arranged against the top face, so as to present a C-shape;
- two C-shaped metal clips engaged respectively on the first base and on the second base;
- and
- two fastener pins, each passing through a clip and the two longitudinal projections of a respective base and a respective orifice of the arm extending in elevation from the bottom face to the top face.
