Description

  

  Verfahren zur Behandlung der     Lagerfläche    von Schalenlagern für Lagerteile  von Verbrennungskraftmaschinen.    Für die Lager der Lagerteile von Kurbel  wellen, Pleuelstangen usw. von Verbrennungs  kraftmaschinen werden neuestens Lager  schalen aus Aluminium verwendet. Der La  gerdruck ist sehr gross, es kann ein Anfressen  stattfinden, insbesondere bei nicht reichlicher  Schmierung, schlechtem Öl usw.  



  Zweck vorliegender Erfindung besteht  darin, die Gefahr des Anfressens zu vermin  dern.     Erfindungsgemäss    wird dieser Zweck  dadurch erreicht, dass man die Lagerflächen  der aus Aluminium bestehenden Lagerschalen  mit einem     -Überzug    aus reibungsvermindern  dem Metall versieht und dann den Lagerteil  in dem Lager einlaufen lässt.  



  Zur Herstellung des     Überzuges    eignet sich  insbesondere Zinn. Dem     Überzug    wird zweck  mässig eine Stärke von etwa 0,01 bis 0,04 mm  gegeben. Das Zinn kann in beliebiger Weise  aufgebracht werden, nur muss die gewünschte  geringe Dicke der Schicht und die grosse  Gleichmässigkeit derselben gewährleistet sein.    Zweckmässig ist zum Beispiel das Nieder  schlagen auf elektrischem Wege, das Auf  spritzen sowie das Auftragen auf chemischem  Wege. Letzteres erfolgt durch geeignete  Stannat-Bäder.  



  Beim Einlaufen des Lagerteils in den La  gern arbeiten sich die Überzüge an den Stel  len ab, an denen der Druck grösser ist als  an den übrigen, und es bildet sich rasch eine  vollkommen gleichmässig belastete Gleit  fläche.



  Method for treating the bearing surface of shell bearings for bearing parts of internal combustion engines. For the bearing of the bearing parts of crankshafts, connecting rods, etc. of internal combustion engines, bearing shells made of aluminum are used recently. The bearing pressure is very high and seizure can occur, especially if there is insufficient lubrication, poor oil, etc.



  The purpose of the present invention is to reduce the risk of pitting. According to the invention, this purpose is achieved by providing the bearing surfaces of the bearing shells made of aluminum with a coating made of friction-reducing metal and then allowing the bearing part to run into the bearing.



  Tin is particularly suitable for producing the coating. The coating is expediently given a thickness of about 0.01 to 0.04 mm. The tin can be applied in any way, only the desired small thickness of the layer and the great evenness of the same must be guaranteed. For example, it is expedient to knock down electrically, spray on and apply chemically. The latter is done using suitable stannate baths.



  When the bearing part enters the warehouse, the coatings work themselves off at the points where the pressure is greater than the rest, and a completely evenly loaded sliding surface is quickly formed.
