Description

KAISERLICHESIMPERIAL

PATENTAMT.PATENT OFFICE.

Gegenstand der Erfindung ist ein Laufring zur Herstellung großer Kugel- oder Rollenlager usw., wie sie beispielsweise für die Eingangsöffnungen eines rotierenden Schiffskörpers nach Patentschrift 156016, Kl. 65 a, in Anforderung kommen.The invention relates to a raceway for producing large ball or roller bearings etc., as for example for the entrance openings a rotating hull according to patent specification 156016, class 65 a, on request come.

Bisher bereitete die Anfertigung großer Kugellager insofern Schwierigkeiten, als es schwer fiel, die Laufflächen der Ringe gleichmäßig gehärtet vorrichten zu können. Nach der Erfindung sind die Laufflächen aus rundlaufenden, aus Bronze, Chromnickelstahl, Resistin usw. bestehenden metallischen Bändern, Drähten usw. von beliebiger Querschnittsform gebildet, welche als einzelne Ringstücke, geschlossene Ringe oder als endloses Band schraubenförmig aufgewickelt in den mit einer geeigneten Metallmasse auszufüllenden Umschlußringen vor dem Gießen konzentrisch zur Drehachse eingelagert sind! Um zu verhüten, daß die eingelagerten harten oder gehärteten Teile sich während des Betriebes wieder loszulösen vermögen, sind sie in solchen Querprofilen hergestellt, daß die eingegossene Metallmasse in die vorgesehenen Nuten, Aussparungen usw. eindringt und so das Loslösen verhindert.So far, the manufacture of large ball bearings has been difficult in that it is difficult fell to be able to prepare the running surfaces of the rings evenly hardened. According to the invention are the running surfaces made of rotating, made of bronze, chrome-nickel steel, resistin, etc. metallic strips, wires etc. formed of any cross-sectional shape, which as individual ring pieces, closed Rings or as an endless band helically wound in the surrounding rings to be filled with a suitable metal compound are stored concentrically to the axis of rotation before casting! To prevent that the stored hard or hardened parts come loose again during operation able, they are made in such transverse profiles that the cast metal mass penetrates into the intended grooves, recesses, etc. and thus prevents loosening.

In der Zeichnung ist die neue Einrichtung erläutert. Fig. 1 und 2 stellen Laufringe im Querschnitt dar, während Fig. 3 bis 5 Aussparungsprofile an den die Laufflächen bildenden Lauf ringt eilen zeigen.In the drawing, the new facility is explained. Fig. 1 and 2 represent races in Cross section, while Fig. 3 to 5 recess profiles on the treads forming Run wrestles rush to show.

In dem U-förmig profilierten Umschlußring a (Fig. 1) sind die aus besonders hartem oder gehärtetem Material bestehenden Ringstücke b oder die geschlossenen Ringe c konzentrisch zum Ring α derart eingelagert, daß sie nach erfolgtem Eingießen der Metallmasse d durch die vorgesehenen Öffnungen e die Lauffläche des Kugellagerringes bilden. Um zu verhüten, daß die Profillage der Laufflächenteile sich wahrend des Gießens verändert, werden dieselben mittels dünner Drähte, welche, soweit hinderlich, später wieder auszufeilen sind, in der richtigen Lage festgehalten. Die Ausdehnungskoeffizienten der verschiedenen Metallarten müssen möglichst gleich sein.In the U-shaped profiled Umschlußring a (Fig. 1), b the group consisting of particularly hard or hardened material ring pieces or closed rings c concentric with the ring α so stored, that after completion of pouring of the metal mass to d through the provided openings e the Form the running surface of the ball bearing ring. In order to prevent the profile position of the tread parts from changing during casting, they are held in the correct position by means of thin wires which, if this is a hindrance, later have to be filed out again. The expansion coefficients of the different types of metal must be as equal as possible.

Fig. 2 zeigt eine trapezähnliche Querschnittsgestalt der eingelagerten Bronzestreifen f, welche sich dem vorzusehenden Bogenprofile des Lagers derart anpaßt, daß das Ablösen der Streifen erschwert und ein fester Zusammenschluß erreicht wird. Nach Fig. 3 bis 5 sind Einfräsungen oder Ausbohrungen usw. g an den Bronzestreifen f vorgesehen, in welche sich die einzugießenden Metallmassen d fest einlagern.Fig. 2 shows a trapezoidal cross-sectional shape of the embedded bronze strips f, which adapts to the arched profile of the bearing to be provided in such a way that the detachment of the strips is made difficult and a firm connection is achieved. According to FIGS. 3 to 5, millings or bores, etc. g are provided on the bronze strips f , in which the metal masses d to be cast are firmly embedded.
