Abstract: A friction spacer adapted to be interposed between two mechanical components in order to transfer a force between the two mechanical components, the friction spacer including a flat part having two opposite surfaces defining a thickness, and a plurality of protuberances projecting from at least one of the surfaces, the protuberances of the plurality of protuberances extending from the at least one of the opposite surfaces by a determined average height. The flat part and the protuberances are produced from the same metal material, and the same metal material continuously extends between the flat part and the protuberances.

Abstract: A screw assembly includes a longitudinal component (10) having two opposite ends and a threaded part (12; 42; 66) so that it can be connected by screwing to one of two elements (34). An elastically deformable member (18, 20; 48; 82) is adapted to be borne, in the axially compressed state, between one or other of the two opposite ends of the longitudinal component (10) and the other of the two elements. The assembly has a retaining device (30; 54; 84) so as to be able to keep the elastically deformable member (18, 20; 48; 82) in compression and so as to be able to release the elastically deformable member in the compressed state between the other of the two elements (32) and the one or the other of the two opposite ends.

Abstract: A metallic locking washer is configured to be mounted in a screw/nut system to engage between a nut and a bearing element. The metallic locking washer has a contact face suitable for coming into contact with one or the other of the nut and the bearing element. The contact face has a surface that is suitable for being brought along in friction against one or the other of the nut and the bearing element when the nut loosens. The contact face is coated, by thermal projection of an additive material, with a rough coating forming a rough surface, which increases the friction forces between the contact face of the metallic washer and one or the other of the nut and the bearing element.

Abstract: A locking washer is to be inserted between a bearing element and a screwable element. The locking washer includes two washer crowns, each of which has an engagement face. The washer crowns which engage with one another and are maintained compressed under axial pressure between the screwable element and the bearing element are capable, when the screwable element is unscrewed, of rotatably engaging with the screwable element, and the bearing element, respectively, so as to rotate the washer crowns relative to one another, in order to rotatably lock the screwable element. According to the invention, the locking washer presents a shape of a truncated cone, and the locking washer is elastically deformable in order to be able to be flattened, forming a spring, such that the axial pressure is maintained substantially constant.

Abstract: The invention relates to a locking washer which is to be inserted between a bearing element (38) and a screwable element (42) and which includes two washer crowns (12, 14), each of which has an engagement face (22, 24). Said washer crowns (12, 14) which engage with one another and are maintained compressed under axial pressure between said screwable element (42) and said bearing element (38) are capable, when said screwable element is unscrewed, of rotatably engaging with said screwable element (42), and said bearing element (38), respectively, so as to rotate said washer crowns (12, 14) relative to one another, in order to rotatably lock said screwable element (42). According to the invention, said locking washer presents a shape of a truncated cone, and said locking washer (10) is elastically deformable in order to be able to be flattened, forming a spring, such that said axial pressure is maintained substantially constant.

Abstract: The invention relates to a locking washer (39) comprising two washer crowns (10, 26) having each an engagement face (11, 11?), the engagement face having a plurality of asymmetrical, radial teeth (16, 16?), each of the asymmetrical, radial teeth having, on the one hand, a crest (20, 20?) and a tooth bottom (18, 18?) separated angularly from the crest; and, on the other, a sliding side (22, 22?) which inclines and extends angularly between the crest (20,20?) and the tooth bottom (18, 18?), wherein the engagement faces (11, 11?) of the washer crowns are suitable for being applied against each other, whereas the sliding sides (22, 22?) come into contact with each other, respectively, along a contact surface. The engagement face (11?) of at least one of the washer crowns (26) has a recess (28) in order to reduce the contact surface of the sliding sides (22, 22?).
