Title (DE) VERFAHREN ZUR HERSTELLUNG EINES KOLBENBOLZENS SOWIE DANACH HERGESTELLTER KOLBENBOLZEN
(EN) METHOD FOR PRODUCING A PISTON PIN AND A PISTON PIN PRODUCED BY SAID METHOD
(FR) PROCEDE POUR REALISER UN AXE DE PISTON, ET AXE DE PISTON AINSI REALISE
Abstract:
(DE) Die Erfindung betrifft ein Verfahren zur Herstellung eines Kolbenbolzens (2) zur Verbindung eines Kolbens einer Hubkolbenmaschine mit einem Pleuel sowie einen danach hergestellten Kolbenbolzen (2), wobei der Kolbenbolzen (2) mit einer Außenhülse (20) und einem Kern (22) ausgebildet wird, die Außenhülse (20) und/oder der Kern (22) in eine Rotation um eine Achse (3) versetzt werden, so dass sie eine Relativdrehung zueinander ausführen, der Kern (22) zumindest teilweise plastifiziert und/oder aufgeschmolzen wird, und die Außenhülse (20, 20’) und der Kern (22) entlang der Achse (3) unter Druck verbunden werden.
(EN) The invention relates to a method for producing a piston pin (2) for connecting a piston of a reciprocating piston engine to a connecting rod, and to a piston pin (2) produced by said method, the piston pin (2) being formed with an outer sleeve (20) and a core (22), the outer sleeve (20) and/or the core (22) being displaced in rotation about an axle (3) so that they rotate relative to one another, the core (22) being at least partially plasticized and/or molten on, and the outer sleeve (20, 20’) and the core (22) being connected under pressure along the axis (3).
(FR) La présente invention concerne un procédé pour réaliser un axe de piston (2) destiné à relier un piston d'une machine à piston alternatif, à une bielle, ainsi qu'un axe de piston (2) ainsi réalisé. Selon l'invention, l'axe de piston (2) est réalisé avec une douille extérieure (20) et un noyau (22); la douille extérieure (20) et/ou le noyau (22) sont mis en rotation autour d'un axe (3) de sorte qu'ils exécutent une rotation relative l'un par rapport à l'autre; le noyau (22) est plastifié et/ou fondu au moins partiellement; et la douille extérieure (20, 20') et le noyau (22) sont reliés sous pression le long de l'axe (3).
