Abstract: An axial retainment system for a shaft is provided. The axial retainment system includes a cylindrical body extending from an outboard end to an inboard end thereof, and a swaged ridge extending radially outward from the cylindrical body proximate the outboard end. The swaged ridge has an outboard axial surface facing toward the outboard end and extending radially outward and terminating at a radially outward facing circumferential surface. The swaged ridge has an inboard axial surface facing toward the inboard end and extending radially outward from the cylindrical body and terminating at the radially outward facing circumferential surface. The outboard axial surface of the swaged ridge is recessed axially inward from the outboard end of the shaft. The inboard axial surface of the swaged ridge is swaged against, conforms in shape to, and is compressed against a component to be axially retained on the shaft.

Abstract: An expandable sleeve for an interference fastener has a hollow elongate stem extending axially between an insertion end and a head portion. The elongate stem has an inside surface and an outside surface. A portion of the stem has a fluted shape and/or has a cylindrical shape with a conical portion.

Abstract: A telescopic shaft for rapid length adjustment consists of a tube having a plurality of alternating circumferential ridges and grooves on at least a portion of an inner surface and having an oval cross-section with a major diameter DA and a minor diameter DB; a shaft disposed within the tube and having matching circumferential ridges and grooves, the shaft also having an oval cross-section with a major diameter DC and a minor diameter DD; and the ridges and grooves of the tube interengaging with the grooves and ridges of the shaft when the shaft major diameter DC is substantially parallel with the tube minor diameter DB.

Abstract: A method for making a lightweight composite camshaft, includes the steps of providing at least one lightweight cam element having a lobed outer surface and a hub with a cylindrical bore, at least a portion of the hub not being radially occluded by the outer surface; providing at least one lightweight journal element having a cylindrical outer surface and a hub with a cylindrical bore, at least a portion of the hub not being radially occluded by said outer surface; providing a hollow cylindrical tubular shaft member having a diameter sized to form a snug sliding fit in the hubs of the cam element and the journal element; positioning the cam and journal elements on the shaft in required axial and radial orientations; and applying means, on the hub of each element and that portion of the shaft which is in registry with the hub, for establishing a permanent interlock to fix each element in its required axial and radial orientation on the shaft.
