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 D and a minor diameter D ; 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 D and a minor diameter D ; and the ridges and grooves of the tube interengaging with the grooves and ridges of the shaft when the shaft major diameter D is substantially parallel with the tube minor diameter D .

Disengageable quick-lock connection for telescopic shaft

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.
