Description

Verfahren zur Herstellung von Verbundlagerschalen Durch das Patent 7o8 o48 ist ein Verfahren zur Herstellung von Verbundlagerschalen, die auf einer Stahlschale mit einer Auskleidung von Bleibronze bestehen, geschützt, nach dem die Bleibronze in die schwach erwärmte Stahlschale eingegossen wird, worauf die Lagerschale so lange auf eine Temperatur erhitzt wird, bei der die Bleibronze in einen teigigen Zustand übergegangen ist und eine innige Verbindung der beiden Werkstoffe durch Diffusion erzielt ist.Method of manufacturing composite bearing shells By the patent 7o8 o48 is a process for the production of composite bearing shells, which are based on a Steel shell with a lead bronze lining, protected after the Lead bronze is poured into the slightly heated steel shell, whereupon the bearing shell as long as it is heated to a temperature at which the lead bronze becomes doughy State has passed and an intimate connection of the two materials through Diffusion is achieved.

Wie Versuche ergeben haben, eignet sich dieses Verfahren auch für Schalen aus Temperguß. Das feste Haften der Bleibronze auf Tempergußschalen ist darauf zurückzuführen, daß die Bleibronze mit Temperguß Mischkristalle in Form einer festen Lösung bildet, wobei das Eisen des Tempergusses in das Kupfer der Bleibronze hineindiffundiert, wenn die Tempei'gußschale mit der Auskleidung von Bleibronze zusammen so lange auf eine Temperatur erhitzt wird, bei der die Bleibronze in einen teigigen Zustand übergegangen ist.As tests have shown, this method is also suitable for Malleable cast iron bowls. The firm adherence of lead bronze to malleable cast iron shells is due to the fact that the lead bronze with malleable cast iron mixed crystals in the form of a solid solution forms, whereby the iron of the malleable cast iron into the copper of the lead bronze diffused in when the Tempei'gußschale with the lining of lead bronze is heated together for so long to a temperature at which the lead bronze in one pasty state has passed.

Die zu verwendende Bleibronze kann aus Blei oder Kupfer oder aus Blei, Kupfer und Zinn mit oder ohne Nickel zusammengesetzt sein.The lead bronze to be used can be made of lead or copper or of lead, Copper and tin can be composed with or without nickel.
