 as well as the type, quantity and condition of the molding compound of the casting mold. These parameters, which influence the heat balance, can be defined or predetermined for given workpieces and conditions.



   With the correct heat balance, the hollow casing between the gunmetal shell and the inner mold wall suddenly becomes apparent through the inlet channel system in a plurality perpendicular to the bearing shell axis
 EMI2.2
 The shell of the storage shell is quenched when it comes into contact with the Rotsuss shell, which serves as the core piece, on the contact surface and then melts the gunmetal core shell by heat transfer from the steel mass through the cooler protective layer formed, whereby the gunmetal core jacket then melts without mixing the gunmetal and steel masses with one another The contact point under the increased shrinkage or shrinkage due to the clamping effect of the solidifying contents of the sprue system.

   Shrinkage pressure of the solidifying reinforcing steel jacket the desired, intimate and uniform welded connection between the two metal parts takes place and through which cooling measures or cooling devices that regulate the solidification of the metal masses and prevent the pressing out of the liquid gunmetal mass under pressure relief are secured.



   The drawing shows, for example, a reinforced bearing shell i cast according to the method
 EMI2.3
 



   The sprues k were created by filling the sprue system when pouring the steel into the mold.



   When the contents of the inlet duct system solidify, the clamping effect described in more detail above arises.

PATENT-ANSPRUCH : Verfahren zur Herstellung armierter Lagerschalen nach Patent Nr. 112361, dadurch gekennzeichnet, dass das Eingusskanalsystem für die geeignet über den Schmelzpunkt erhitzte Stahlmasse des Armierungsmantels mit mehreren Angüssen senkrecht zur Lagerschalenachse derart in der Längs-und insbesondere Querrichtung der Form geführt ist, dass bei der Erstarrung und der dadurch hervorgernfenen Schwindung der Füllung des Eingusskanalsystems sieh ein Klammersystem ergibt, welches mit einer den Schwindungs- bzw. Schrumpfdruck des erstarrenden Armierungsmantels erhöhenden Presswirkung diesen Armierungs- EMI2.4 EMI2.5 PATENT CLAIM: Process for the production of reinforced bearing shells according to patent no.112361, characterized in that the sprue system for the steel mass of the reinforcement jacket, which is suitably heated above the melting point, is guided with several sprues perpendicular to the bearing shell axis in the longitudinal and in particular transverse direction of the mold in such a way that during solidification and the resulting shrinkage of the filling of the sprue system results in a clamp system which, with a pressing effect that increases the shrinkage or shrinkage pressure of the solidifying reinforcement jacket, EMI2.4 EMI2.5
