Abstract
Gyrocraft rotor head including a hub connected to each blade (2) of the rotor by a linking member which is integral with the blade (2) and which is linked to the hub body by a laminated spherical stop. Each blade (2) is fitted with an assembly (20) for elastic recall in drag with incorporated damping, one of whose extremities (22) is linked to the member linking the blade to the hub body. The linking member is constituted by an intermediate sleeve (11) comprising one part in the form of a ring (12) and one part fitted with at least one double clevis (14), the intermediate sleeve (11) being a single integral assembly of which the ring (12) surrounds the laminated spherical stop with which it is integrated and of which the double clevis or clevises interact with the structure for integration of the blade (2).
