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. The diameter of the first cylindrical portion is less than the diameter of the semi-cylindrical portion.
