Description
Verfahren zur Herstellung einer Buncllagerschalenhälfte aus einem mit Bleibronze plattiertelSStahlblech Die Erfindung betrifft ein Verfahren zur Herstellung einer Bundlagerschalenhälfte mit einer Stahlstützschale und einer an der Lauffläche und am Bund aufplattierten Lagermetallschicht aus einem flachen Stahlstreifen, der mit einer aufgegossenen Bronzeschicht plattiert ist, bei dem der Streifen nach dem rechtwinkligen Umbiegen der Flanschen in Halbzylinderform gebogen wird. Beim Abbiegen des seitlichen Bundes an derartigen flachen Blechstreifen läßt es sich nicht vermeiden, daß die Bleibronze am übergang in den Bund rissig wird, da sie die für das Aasbiegen erforderliche Dehnung nicht aufzunehmen vermag. Es ist bekannt, diese Erscheinung dadurch zu beseitigen, daß man die Bronze vor dem Aasbiegen des Bundes an der Stelle von dem Eisenblech entfernt, wo nachher das Abbiegen vorgenommen wird, so daß am fertigen Lager eine Nut sichtbar ist, welche die Bronze der Lauffläche von derjenigen des seitlichen Bundes trennt. Die Entfernung der Bronze an dieser Stelle erfordert in jedem Falle einen besonderen Arbeitsgang, der eine Verteuerung des Lagers bedeutet. Weiter besteht die Gefahr, daß beim Entfernen der Bronze die durch das Aufgießen der Bronze spröde Stahloberfläche Kerben erhält, die bei Abbiegung oder im späteren Dauerbetrieb zu Rissen führen.Process for the production of a bunch bearing shell half from a Steel sheet plated with lead bronze The invention relates to a method of production a flange bearing shell half with a steel support shell and one on the running surface and a bearing metal layer made of a flat steel strip that is clad on the collar, the is plated with a cast bronze layer, in which the strip after the right-angled bending of the flanges is bent into a semi-cylindrical shape. When turning of the lateral collar on such flat sheet metal strips, it cannot be avoided that the lead bronze is cracked at the transition to the collar because it is the one for carrion bending is unable to absorb the required elongation. This phenomenon is well known to be eliminated by placing the bronze in place before carving the covenant removed from the iron sheet, where the turning is made afterwards, so that on finished bearing a groove is visible showing the bronze of the tread of the one the lateral collar separates. The removal of the bronze at this point requires in each case a special operation, which means an increase in the cost of the warehouse. There is also the risk that when the bronze is removed, the result of the pouring process The bronze's brittle steel surface receives notches that appear when it is bent or later Continuous operation can lead to cracks.
Erfindungsgemäß vermeidet man diesen Mangel und erspart auch in den meisten Fällen die Entfernung der Bronze an den Biegestellen zumindest bis auf den Stahlgrund dadurch, daß vor dem Umbiegen der Flansche die Flanschbiegestellen zu beiden Seiten an ihren Rändern durch in Längsrichtung des Bleches verlaufende Kerben eingefußt werden. In der beiliegenden Zeichnung ist ein Beispiel zeichnerisch dargestellt.According to the invention one avoids this deficiency and also spares in the in most cases the removal of the bronze at the bending points at least except for the Steel base in that the flange bending points are closed before the flanges are bent both sides at their edges by notches running in the longitudinal direction of the sheet be infused. An example is shown in the accompanying drawing.
Abb. z zeigt den geraden Zweistoffstreifen, bei dem in der Bronzeschicht a die vier Kerben b; e, d, e durch einfaches Ritzen angebracht sind. Jeweils die Kerben b und c sowie d und e besitzen einen solchen Abstand voneinander, daß sie denjenigen Teil der Bronze zwischen sich einfassen, der beim Abkanten unter Zugspannungen kommt. Werden nun die seitlichen Bunde aasgebogen, so daß ein U-förmiges Stück gebildet wird, so entstehen die Risse von den Kerben ausgehend derart, daß die Lauffläche i und die Bunde ä und h rißfrei bleiben. Die jeweils zwischen den Kerben b und c sowie d und e befindliche Bronze kann .nachträglich entfernt werden, wenn eine Abfasung der Lager an dieser Stelle gewünscht wird.Fig. Z shows the straight two-material strip in which the four notches b; e, d, e are attached by simply scratching. The notches b and c as well as d and e have such a distance from one another that they enclose that part of the bronze between them which comes under tensile stress during bending. If the lateral collars are now bent so that a U-shaped piece is formed, the cracks arise from the notches in such a way that the running surface i and the collars ä and h remain free of cracks. The bronze located between the notches b and c as well as d and e can be removed later if a chamfering of the bearing is desired at this point.
