Abstract: The present invention relates to a bearing for maintaining an inner mobile structural component with revolution symmetry, rotating inside an outer structural component, which is itself fixed or mobile, said bearing comprising a set of balls and at least one joining member which provides the mechanical contact between said balls and said outer structural component, said bearing also comprising a pressurized-oil damper known as a “squeeze film” damper, arranged at the annular contact surface between said joining member and the outer structural component, said bearing comprising at least two annular elastic seals, each arranged in a groove, at the edges of said annular contact surface, wherein the annular elastic seals are U-shaped lip seals, the hollow space of which is directed towards the “squeeze film”, or are E-type seals, the hollow spaces of which are directed towards the “squeeze film”, the leakproofing for each seal being ensured by the contact between said seal and t

Abstract: The present invention is related to a bearing for maintaining an inner mobile structural component with a revolution symmetry, rotating inside an outer structural component, which is itself fixed or mobile, said bearing comprising a set of balls or rollers and at least an outer race which provides the mechanical contact between said balls or rollers and said outer structural component, said bearing also comprising a pressurized-oil damper known as a “squeeze film” damper, arranged at the annular contact surface between said outer race and the outer structural component, characterized in that each side surface of the outer race is in contact with a side seal having an annular form, said seals being securely fastened to the outer race by means of a series of anti-rotation fixing members.

Abstract: The present invention relates to an axisymmetric structural component, one of the ends of which is fitted with an inner circular flange for assembling, by bolting. The axisymmetric structural component with a second axisymmetric structural component. The flange comprises housings for receiving fixing elements such as bolts, pins or threaded rods. The housings are arranged on the circumference of the said flange at regular intervals. Each housing is, in longitudinal section (A—A) along a plane passing through the rotational axis of the component, T-shaped and consists of a first essentially cylindrical portion which is longitudinally open on the inner face (x) of the axisymmetric structural component and transversely open on the contact face (y) of the flange in the assembly. A second essentially semi-cylindrical portion is mounted on the flange which is also longitudinally open on the inner face (x) of the said structural component having an essentially D-shaped transverse section.

Abstract: The present invention relates to a bearing for maintaining an inner mobile structural component (2) with revolution symmetry, rotating inside an outer structural component (1), which is itself fixed or mobile, said bearing comprising a set of balls (3) and at least one joining member (4, 4′) which provides the mechanical contact between said balls (3) and said outer structural component (1), said bearing also comprising a pressurized-oil damper known as a “squeeze film” damper, arranged at the annular contact surface (5) between said joining member (4, 4′) and the outer structural component (1), said bearing comprising at least two annular elastic seals (9, 9′, 19, 19′), each arranged in a groove (6, 6′), at the edges of said annular contact surface (5), wherein the annular elastic seals are U-shaped lip seals (9, 9′), the hollow space of which is directed towards the “squeeze film”, or are E-type seals (19, 19′), the hollow spaces of which are
