Abstract:
A friction- and form-grip connection of first and second rotating components which have different expansion behavior in a region of the connection during rotation, the form grip being effected via a centering seat and the friction grip between the first and second rotating components being effected by means of axially prestressed elements, at least one of the components having a cavity in the interior, wherein an insert ring, which exerts a radial force on the centering seat during operation, is arranged in the cavity, wherein the centering seat has a double-conical contact surface, and wherein the component having a positive centering offset and the insert ring are made of a material which has a higher coefficient of expansion than the material of the component having a negative centering offset, in the cavity of which the insert ring is accommodated.
