Abstract:
A conical clamping set for connecting an inner component with a cylindrical outer-circumference surface with an external component with a recess with a cylindrical inner-circumference surface, which set is intended to be located in a radial clearance between the cylindrical outer-circumference surface of the inner component and the cylindrical inner-circumference surface of the recess of the external component comprising,at least two inner conical rings, each having a cylindrical inner-circumference surface for application to the cylindrical outer-circumference surface of the inner component, and a conical outer-circumference surface,a thin-walled, external, double-cone ring with conical, inner-circumference surfaces, the ends of which are turned towards each other and fitting in parallel engagement against the outer-circumference surfaces of the at least two inner conical rings, the double-cone ring further including a cylindrical outer-circumference surface for application on the inner-circumference surface of the external component,at least two axial clamping screws distributed over the circumferences of the at least two conical rings, allowing the conical rings to be axially pulled against one another thereby sliding down over the conical surfaces of the double-cone ring and expanding the double-cone ring radially outwardly thereby generating radial clamping forces acting against the outer-circumference surface of the inner component and the inner-circumference surface of the recess of the external component,the double-cone ring having a radial step down going through in the direction of the circumference in its cylindrical outer-circumference surface and being substantially in the center of its axial extension on an axial section, so that the axial extension of an outer zone of forces in the cylindrical outer-circumference surface of the double cone ring, in which the radial clamping forces are transferred to the inner-circumference surface of the recess of the external component, is smaller than the axial extension of an inner zone of forces, in which the radial clamping forces act against the outer-circumference surface of the inner component.
