Description
Radial geteiltes Rollen- oder Kugellager für eingebaute gekröpfte Wellen Im Motoren- und Maschinenbau müssen aus Montagegründen bei eingebauten aus einem Stück hergestellten und mehrfach gekröpften Wellen nur Wälz- und Kugellager mit geteilten Laufringen (z. B. deutsche Patentschriften 851147 und 857 455) verwendet werden. Derartige bekannte Lager sind vollkommen aus Stahl gefertigt und bestehen aus. je einem zwei- oder mehrteiligen Lageraußen- und -innenring, die an ihren Schnittflächen (Stoßstellen) spitzwinklig ineinandergreifen und mittels Keilen zusammengehalten werden. Die Herstellung solcher Lager in die formgerechte Gestaltung verlangt eine allseitige Bearbeitung mit empfindlichen und teuren Werkzeugen, wie Drehstählen, Fräsern und Schnitten, die einem großen Verschleiß und Kostenaufwand unterworfen sind; außerdem ist dabei noch ein erheblicher Zeitaufwand, in der Fabrikation erforderlich.Radially split roller or ball bearings for built-in offset Shafts In engine and mechanical engineering, for assembly reasons, when installed one piece manufactured and multiple cranked shafts only roller and ball bearings with split races (e.g. German patents 851147 and 857 455) are used will. Such known bearings are made entirely of steel and exist the end. a two-part or multi-part bearing outer and inner ring, which are attached to their cut surfaces (Joints) interlock at an acute angle and held together by means of wedges will. The production of such bearings in the correct design requires a all-round machining with sensitive and expensive tools such as turning tools, Milling cutters and cuts that are subject to great wear and tear and cost are; In addition, a considerable amount of time is required in the manufacture.
Vorliegende Erfindung vereinfacht und verbilligt die Herstellung derartiger Lager. Bei ihr sind die Laufringteile nicht mehr ganz aus Stahl in einem Stück hergestellt, sondern die geteilten Lageraußen-und -innenringe aus Kunststoff od. dgl. im Spritzverfahren hergestellt. In die Ringe ist ein Stahlband, als Lauffläche dienend, ebenfalls geteilt, mit eingespritzt. Dabei werden die Lageraußen- und -innenringe mit breiten Nuten versehen, in welche die aus Stahlband bestehenden Laufflächen eingeschoben werden können, wenn die abgenutzten Bänder ausgewechselt werden müssen.The present invention simplifies and makes the production of such a device cheaper and cheaper Camp. With her, the raceway parts are no longer made entirely of steel in one piece, but the split bearing outer and inner rings made of plastic or the like in an injection molding process manufactured. A steel band serving as a running surface is also divided into the rings, injected with. The bearing outer and inner rings are made with wide grooves provided, into which the running surfaces made of steel strip are inserted when the worn belts need to be replaced.
In der Zeichnung ist die Erfindung beispielsweise als zweiteiliges Rollenlager dargestellt.In the drawing, the invention is shown, for example, as a two-part Roller bearings shown.
Fig. 1 zeigt den geteilten äußeren Laufring und Fig. 2 den zugehörigen, ebenfalls geteilten inneren Laufring, beide in Seitenansicht, während Fig. 3 und 4 die jeweilig zugehörigen Querschnitte darstellen; Fig. 5 zeigt im Querschnitt die eingesetzte Laufrolle mit Stahlband; in Fig. 6 und 7 ist als Einzelheit eine Stoßstelle der Laufringe isometrisch veranschaulicht.Fig. 1 shows the divided outer race and Fig. 2 the associated, also split inner race, both in side view, while Fig. 3 and 4 show the respective associated cross-sections; Fig. 5 shows in cross section the roller used with steel belt; in Figs. 6 and 7 is a detail Isometric illustration of the joint of the races.
Der Lageraußenring und der Innenring, beide radial geteilt, aus Kunststoff im Spritzverfahren hergestellt, bestehen jeweils. aus zwei Ringhälften 1, 1a und 2, 2a, die an ihren Stoßstellen 3 und 4 spitzwinklig ineinandergreifen, damit gegen ein seitliches Verschieben ein sicherer Sitz gewährleistet ist. An den ineinandergreifenden Stoßstellen halten quer eingeschobene Keile die Ringhälften zusammen, wie aus der Zeichnung ersichtlich bei 5 den äußeren Ring und bei 6 den inneren Ring. In den äußeren und inneren Kunststoff- oder dergleichen Ring sind breite Nuten 7, 8 vorgesehen, in die jeweils ein Stahlband 9, 10, als Rollen- oder Kugellauffläche dienend, eingelegt ist. Sind diese Bänder abgenutzt, so können diese aus den Nuten herausgezogen und neue Bänder eingeschoben werden. Zuvor werden die Haltekeile 5, 6 für das Zerlegen des Lagers bzw. Demontage seitlich herausgezogen oder beim Wiederzusammensetzen des Lagers (Montage) wieder eingeschoben.The bearing outer ring and the inner ring, both radially divided, made of plastic manufactured by injection molding, exist in each case. from two ring halves 1, 1a and 2, 2a, which interlock at their joints 3 and 4 at an acute angle, thus counteracting lateral shifting ensures a secure fit. On the interlocking Joints hold the ring halves together, as from the Drawing can be seen at 5 the outer ring and at 6 the inner ring. In the outer and inner plastic or similar ring, wide grooves 7, 8 are provided, in each of which a steel band 9, 10, serving as a roller or ball running surface, is inserted is. If these bands are worn, they can be pulled out of the grooves and new tapes are inserted. Before doing this, the retaining wedges 5, 6 are used for dismantling of the bearing or dismantling pulled out sideways or when reassembling of the bearing (assembly) pushed in again.
