Description

Verfahren zum Fertigen von vergüteten Segmenten großer, kreisringförmiger Kugel- oder Rollenbahnen, insbesondere für Schwenkwerke von Baggern, Kranen od. dgl. Es ist bekannt, zum Fertigen von vergüteten Segmenten großer, kreisringförmiger Kugel- oder Rollenbahnen, insbesondere für Schwenkwerke von Baggern, Kranen od. dgl., das Profil der Kugel- oder Rollenbahn aus geraden Rohlingen von einfachem Profil allseitig spanabhebend herauszuarbeiten, wobei die Rohlinge zunächst so weit spanabhebend, z. B. auf einer Hobelmaschine, bearbeitet werden, daß sie bis auf ein Übermaß das Bahnprofil erhalten. Darauf werden die so entstandenen Halbwerkstücke entsprechend der Krümmung der Bahn gebogen, vergütet und auf einer Drehbank fertig verarbeitet.Process for the production of tempered segments of large, circular ring-shaped Ball tracks or roller tracks, especially for slewing gears of excavators, cranes or the like. Like. It is known for the production of tempered segments of large, circular ring-shaped Ball tracks or roller tracks, especially for slewing gears of excavators, cranes or the like. Like., The profile of the ball or roller track made of straight blanks of simple Work out the profile on all sides by cutting, with the blanks initially so far machining, e.g. B. on a planer, processed that they are up to get an excess of the track profile. The resulting half-workpieces are then placed on it bent according to the curvature of the track, tempered and finished on a lathe processed.

Durch dieses Verfahren wurden die wegen der Notwendigkeit, die gesamte Bearbeitung der Rohlinge auf einer Spezialmaschine, nämlich auf einer Horizontaldrehbank, durchzuführen, vergleichsweise hohen Fertigungskosten älterer bekannter Verfahren wesentlich vermindert.Through this procedure, the because of the need were the whole Machining of the blanks on a special machine, namely on a horizontal lathe, perform, comparatively high manufacturing costs of older known methods significantly reduced.

Es hat sich gezeigt, daß auch das eingangs beschriebene Verfahren noch verbesserungsfähig ist. Gemäß der Erfindung wird deshalb vorgeschlagen, das Herausarbeiten des Bahnprofils bis auf ein Übermaß durch Schmieden vorzunehmen. Diese Maßnahme hat den wesentlichen Vorteil, daß bei der Bearbeitung der Rohlinge durch die spanabhebende Vor- und auch Endbearbeitung nicht mehr die im allgemeinen ungünstige Mitte des Gusses angeschnitten wird. Vielmehr wandert diese beim Schmieden so weit nach innen, daß ein Anreißen auch bei der Vor- und Fertigbearbeitung mit Sicherheit vermieden wird.It has been shown that the method described at the beginning there is still room for improvement. According to the invention it is therefore proposed that Carry out machining of the track profile to an oversize by forging. This measure has the significant advantage that when machining the blanks due to the machining pre-machining and also the final machining no longer the general one inconvenient center of the casting is cut. Rather, this wanders during forging so far inwards that there is also a marking during the preliminary and final machining Security is avoided.

Die Zeichnung zeigt ein Ausführungsbeispiel eines gemäß der Erfindung hergestellten Segmentes, und zwar in Fig. 1 einen Querschnitt durch einen Teil einer Schwenkwerklagerung, z. B. für einen Bagger und in Fig. 2 einen Schnitt durch ein Segment in den verschiedenen Bearbeitungsstufen.The drawing shows an embodiment of one according to the invention manufactured segment, namely in Fig. 1 a cross section through part of a Slewing gear bearing, e.g. B. for an excavator and in Fig. 2 a section through a Segment in the various processing stages.

Die Schwenklagerung weist nach Fig. 1 eine untere und eine obere Kugelbahn 1 bzw. 2 auf, zwischen denen die durch Käfige 3 im Abstand voneinander gehaltenen Kugeln 4 laufen. Die Kugelbahnen 1, 2 sind aus Segmenten zusammengesetzt und an Trägern 5, 6 des Baggerunterbaues bzw. des schwenkbaren Baggeroberbaues befestigt.According to FIG. 1, the pivot bearing has a lower and an upper ball track 1 and 2, between which the cages 3 held at a distance from each other 4 balls run. The ball tracks 1, 2 are composed of segments and are on Supports 5, 6 of the excavator substructure or the pivoting excavator superstructure attached.

Als Rohling für die Segmente der Kugelbahnen dienen gerade, volle Stücke mit rechteckigem Querschnitt. Diese Rohlinge werden zunächst auf den durch die Linie 7 gekennzeichneten Querschnitt geschmiedet. Dabei wandert die ungünstige, durch die strichpunktierte Linie 8 dargestellte Kernzone in den gestrichelt gezeichneten Bereich 9, so daß nunmehr die weitere, bekannte Vorbearbeitung ohne die Gefahr des Anreißens des Bereiches 9 bis auf den durch die Linie 10 gekennzeichneten Querschnitt erfolgen kann.Straight, solid ones are used as the blank for the segments of the ball tracks Pieces with a rectangular cross-section. These blanks are first applied to the the line 7 marked cross-section forged. The unfavorable, by the dash-dotted line 8 shown core zone in the dashed lines Area 9, so that now the further, known preprocessing without the risk of Scribing the area 9 except for the cross-section indicated by the line 10 can be done.

Das bis auf den Querschnitt entsprechend der Linie 10 vorbearbeitete Stück wird darauf entsprechend dem Durchmesser der Kugelbahn gebogen, vergütet und in ebenfalls bekannter Weise auf einer Horizontaldrehbank auf den endgültigen Querschnitt 11 fertig bearbeitet.The preprocessed except for the cross section according to line 10 The piece is then bent, tempered and made according to the diameter of the marble run in a known manner on a horizontal lathe on the final cross-section 11 finished.
