Method and device for producing a strong connection using centrifugal force

摘要

The method for producing a material connection of two bodies (3) with contact surfaces (4), comprises aligning the bodies to each other, contacting the bodies along the contact surfaces to form an assembly, influencing a vertically directed pressure force (F(A)) on the contact surfaces at a predetermined temperature, compatibly fixing the bodies standing in contact with one another, arranging the bodies in a predetermined relative position with a vertical axis distance (8) to a first rotation axis (1), and rotating the bodies around the first rotation axis with adjustable rotational speed. The method for producing a material connection of two bodies (3) with contact surfaces (4), comprises aligning the bodies to each other, contacting the bodies along the contact surfaces to form an assembly, influencing a vertically directed pressure force (F(A)) on the contact surfaces at a predetermined temperature, compatibly fixing the bodies standing in contact with one another, arranging the bodies in a predetermined relative position with a vertical axis distance (8) to a first rotation axis (1), and rotating the bodies around the first rotation axis with an adjustable rotational speed given over a predetermined process duration where a centrifugal force acting on the bodies is produced. The centrifugal force partly acts as pressure force on the contact surfaces. The temperature is lesser than a melting temperature or a softening temperature of the body. The rotational speed and the temperature are changed over the process duration. The relative position of the body and the relative position of the contact surfaces are changed for the first rotational speed during the process duration. The axis distance is changed over the process duration to change the centrifugal force. The first rotational speed is runningly set through the body. The bodies are indirectly contacted over their contact surfaces. Before aligning the bodies to each other, an auxiliary material is introduced between the contact surfaces where the bodies are indirectly contacted. An independent claim is included for a device for producing a material connection of two bodies with contact surfaces.
