  • Friction- and form-grip connection of rotating components
    Patent number: 6276863
    Abstract: In a friction- and form-grip connection of rotating components (1, 2) which have different expansion behavior in the region of the connection during rotation, the form grip is effected via a stepped centering seat (3). The friction grip between the two components is effected by means of axially prestressed elements. At least one of the components has a cavity (6) in the interior, in which cavity (6) an insert ring (7), which exerts a radial force on the centering seat (3) during operation, is arranged. The prestressed insert ring (7) bears with only part of its axial extent against the component (1) interacting with it.
    Type: Grant
