A resonator provided with a heavy member comprising a casing fastened a spring blade. The heavy member comprises a set of masses that is movable in translation in said casing along a longitudinal direction. A wormscrew driven by drive means is engaged in a slider nut of said set of masses. The set of masses comprises two masses that are slidable respectively in two cylindrical spaces of the casing. Each mass presents at least two presser means interposed between the mass and the casing, each presser means comprising a groove formed in a circumference of a mass, each presser means comprising at least one resilient member arranged in said groove and a split ring pressed against the casing by said at least one resilient member of the presser means.

Resonator, and an aircraft provided with the resonator

A ball joint mechanism between a connecting rod () and at least one journal (') is provided. A lateral protection part (&#x2032;) interposed between the connecting rod () and the journal (&#x2032;) is arranged as a one-piece ring comprising a wear member (&#x2032;) and a fastener member (&#x2032;) that are secured to each other. The fastener member (&#x2032;) is made of hard material and is interposed with axial clamping between the journal (&#x2032;) and a shoulder (&#x2032;) of an assembly pin () between the connecting rod () and the journal (&#x2032;) via opposite end faces thereof with a space being arranged between them to receive the wear member (&#x2032;).

Ball-joint mechanism between a clevis and a connecting rod, in particular for control apparatus of a rotorcraft

The rolling bearing of this bearing assembly is of the relubricatable type and is mounted tightly on the shaft by its inner race in such a way as to be prevented from rotating and translating on the shaft, the latter for this purpose comprising a thrust shoulder The outer race of the rolling bearing is housed in a ball swivel with a spherical outer peripheral surface consisting of two half ball swivels back to back and this ball swivel is itself mounted in the spherical housing of a support consisting of two flanges arranged facing one another and slightly separated from one another in the axial direction prior to clamping. One of these flanges may be fixed by lugs to the structure of the craft and the other flange may be fixed to the previous one using screws
