Patent ID: 8657543

Claim:
A device for mechanically linking with a rotating axis at least two parts, which is configured to extend in a longitudinal direction in coaxial bores formed respectively in the at least two parts hinged in relation to each other around the axis, the device comprising: a cylindrical body including at least one end portion including at least one longitudinal slot, the cylindrical body including in the longitudinal direction a cylindrical bore extended by a frusto-conical bore, the frusto-conical bore formed into the cylindrical body and extending in the at least one end portion that is configured to be located in a bore of one of the at least two parts; an insert of frusto-conical shape substantially complementary to the frusto-conical bore, the insert including a tapped aperture extending in the longitudinal direction when the insert is accommodated in the frusto-conical bore; and a screw with a threaded end configured to cooperate by screwing with the tapped aperture of the insert allowing locking of the cylindrical body in the bore of the one of the at least two parts and making a rotary joint around the cylindrical body for another of the at least two parts.
