Connected component assembly having conical clamping sleves

A component assembly for clamping a first component and an axially adjacent second component by a conical clamping system arranged in axially aligned bores of the first component and the second component, the assembly including an inner sleeve part that has a central bore and a conical outer circumferential surface extending concentrically thereto and having a first conical angle in a self-locking range, the assembly further including a bushing-like, outer sleeve part that has a cylindrical outer circumferential surface and a conical inner circumferential surface having a second conical angle generally the same as said first conical angle, the inner circumferential surface being matched to interact with the conical outer circumferential surface of the inner sleeve part, the assembly further comprising a clamping bolt that engages said central bore from an end of the conical clamping system, the bolt having a head for supporting itself against an adjacent end of one of said inner sleeve part or said outer sleeve part which allows said sleeve parts to be displaced toward one another sliding axially over the conical surfaces as the outer sleeve part expands radially, wherein at one end, the outer sleeve part supports a radial circumferential projection that rests axially against the outside of the second component, while the other end of the outer sleeve part is cylindrical throughout and has a diameter that corresponds to the diameter of the bore configured as a blind bore in the first component, and a coaxial threaded bore of a smaller diameter is provided in the bottom of the blind bore.
