Abstract:
A cam supporting arrangement, comprising: a core of a composite camshaft; a cam that is forced over said core and having a cylindrical round bore; a round funnel-shaped core-insertion section in said bore and having at least two mutually aligned conical extents of circular cross-section, each conical extent expanding outward at a different apical angle, said round funnel-shaped core insertion section having a wider funnel-shape round section at its entrance region; said core being a round hollow cylinder with corrugations for seating said cam securely and precisely centered, said round funnel-shaped core-insertion section being at least as wide as said corrugations, said round bore being narrower than said corrugations so that said corrugations are compressed when said cam is seated on said corrugations for producing a tight fit between said cam and said core by plastic and resilient deformation of said corrugations, said round funnel-shaped core insertion section being concentric with said round hollow cylindrical core.
