Patent ID: 6902347

Claim:
A device for connecting first and second components, comprising: a cylindrical fitting plug arranged on the first component and comprising a radially projecting annular surface surrounding the fitting plug at its root; a cylindrical fitting bore arranged in the second component for receiving the fitting plug, and comprising an annular surface surrounding the fitting bore at its edge; a clamp bolt, which is movably guided with a cylindrical guide surface in a transverse bore in the fitting plug, and has on its axially facing ends an internal or external cone concentric with respect to said guide surface, and the length of which clamp bolt is smaller than the diameter of the fitting plug in the area of the transverse bore; and two retainers, which are inserted into radial bores which are diametrically opposed in the area of the fitting bore and are provided with an internal thread, and which retainers have an external or internal cone extending toward the inside of the fitting bore and being complementary with respect to the internal or external cone of the clamp bolt, and which retainers can be tensioned wedge-like with the clamp bolt during the tensioning operation, whereby the internal and external cones, which are complementary with respect to one another, have in pairs an axial shift causing during the tensioning operation the pulling of the fitting plug into the fitting bore and a mutual pressing of the annular surfaces against one another, and whereby one of the retainers is designed as a stop bolt fixed on the second component and the other retainer as a motion screw operable during the tensioning operation, wherein the internal and external cones, which are complementary to one another, have on the side of the stop bolt a smaller cone angle than on the side of the motion screw, and wherein the cone angles on the side of the stop bolt are 40° to 80° and on the side of the motion screw 70° to 120°.
