ABSTRACT:
Friction-welded connection between a sheet metal element and a therein inserted rotation body. The sheet metal element is provided with a protruding, circular annular wall as a pressure face, which pressure face is adapted to be engaged by the rotation body with a counter-pressure face. At least one pressure face is of such conicity that the insertion of the rotation body loads the annular wall with increasing pressure, there being formed a friction-welded connection between rotation body and annular wall as a result of rotation of the rotation body.
