IMPROVEMENTS IN & RELATING TO IMPROVING THE INTEGRITY OF THE UNION BETWEEN COMPONENTS

摘要

An improved method of shrink fit assembly of two components increases resistance to torsional and/or axial loads without the need for a separate key element. Use of a roughened surface, in combination with a softer deformable material, creates a keyed type interaction at the contact areas of the shrink fitted components. One of the shrink fitted components may comprise the softer material, though intermediate layers and sleeves can be used.
