发明名称 Method for screwing skirt and crown parts of a metal piston together
摘要 A method for screwing together two metal parts that are spaced apart from one another close to a screw connection element and elastically deformable relative to one another, and for the remainder lie against one another. In order to obtain a firm and secure screw connection, with little expenditure of torque, one of the metal parts is deformed, before the metal parts are screwed together, in such a manner that regions close to the screw connection element come close to one another, and the metal parts are then screwed together. A region of the one metal parts remains deformed after they have been screwed together, as a result of the screw connection element.
