Patent ID: 10954981

Abstract:
A radial expansion system for a fastener is disclosed. The radial expansion system can include a plurality of wedge guides. Each wedge guide can have at least one guide surface. The plurality of wedge guides can be operable to be movably arranged along an axis with the guide surfaces of adjacent wedge guides opposing one another. The radial expansion system can also include a plurality of expansion wedges. Each expansion wedge can have wedge surfaces configured to slidingly interface with the at least one guide surface. Each expansion wedge can also have a clamp surface operable to interface with an interior portion of a first component. The plurality of expansion wedges can be operable to be disposed between adjacent wedge guides such that the wedge surfaces interface with the opposing guide surfaces. A second component and the plurality of wedge guides can be operable to be drawn toward one another by a fastener to cause the plurality of expansion wedges to displace radially outward from the axis such that the clamping surfaces engage and apply a clamping force to the interior portion of the first component, and thereby couple the first and second components to one another.
