Abgedichteter GelenkkopfSealed joint head
Die Neuerung betrifft einen abgedichteten Gelenkkopf mit einem Gehäuse, einer im Gehäuse festgelegten Laufschale, einem in der Laufschale gelagerten Innenring, einer im Innenring festgelegten Bohrungsbüchse, die in axialer Richtung außerhalb des Innenrings je einen drehbar gelagerten Nutring zur Aufnahme des inneren Endrings je einer Dichtmanschette trägt, und mit je einer Befestigungseinrichtung für die äußeren Endringe der Dichtmanschetten.The innovation relates to a sealed joint head with a housing, a running shell fixed in the housing, one in the Inner ring mounted on the running shell, one fixed in the inner ring Bore bushing, which in the axial direction outside of the inner ring each have a rotatably mounted groove ring for receiving the inner end ring each carries a sealing collar, and each with a fastening device for the outer end rings of the Sealing sleeves.
Gelenkköpfe müssen bei Anwendung in Bereichen mit hoher Verschmutzungsgefahr durch Dichtmanschetten aus Gummi oder aus gummiähnlichem Material abgedichtet v»erden. Die Dichtmanschetten greifen einerseits mit ihren inneren Endringen in einen Nutring ein, der verdrehbar auf der Bohrungsbuch.se angeordnet ist. Die äußeren Endringe der Dichtmanschetten sinJ. bei einer bekannten Ausführungsform in je einen Nutring aufgenommen, der seinerseits in einen Einstich des Gelenkkopfgehäuses eingesetzt ist. Diese Ausführungsform ist verhältnismäßig aufwendig, da auch für die Festlegung der äußeren Endringe der Manschetten zusätzlicheRod ends must be sealed with sealing sleeves made of rubber or rubber-like material when used in areas with a high risk of contamination. On the one hand, the sealing collars engage with their inner end rings in a grooved ring which is rotatably arranged on the Bohrungsbuch.se. The outer end rings of the sealing sleeves are J. in a known embodiment each received in a groove ring, which in turn is inserted into a recess in the joint head housing. This embodiment is relatively expensive, since there are also additional ones for fixing the outer end rings of the cuffs

Nutringe angefertigt und in die Einstiche eingepaßt werden müsserGrooved rings and must be fitted into the grooves
Bei einer anderen bekannten Ausführungsform sind die äußeren Endringe der Manschetten an ringförmigen Kontermuttern anvulkanisiert, die von beiden Seiten her axial in das Gelenkkopfgehäuse eingeschraubt sind und dadurch gleichzeitig die Laufschale des Gelenkkopfes am Gehäuse festlegen. Bei dieser Ausführungsform ist der Austausch der dem Verschleiß unterworfenen Dichtmanschetten schwierig, da hierzu die Kontermuttern herausgeschraubt und andere Kontermuttern mit neuen Dichtmanschetten eingeschraubt werden müssen, so daß nach dem Auswechseln das Spiel des Lagers neu eingestellt werden muß.In another known embodiment, the outer end rings are the cuffs are vulcanized onto ring-shaped lock nuts, which are axially inserted into the joint head housing from both sides are screwed in and thereby fix the bearing shell of the joint head to the housing at the same time. In this embodiment is It is difficult to replace the sealing sleeves that are subject to wear because the lock nuts are unscrewed and others Lock nuts with new sealing collars must be screwed in so that the play of the bearing is readjusted after replacement must become.
Durch die Neuerung soll ein abgedichteter Gelenkkopf geschaffen werden, bei dem die Befestigung der Dichtmanschetten vereinfacht ist.The aim of the innovation is to create a sealed joint head in which the fastening of the sealing sleeves is simplified is.
Diese Aufgabe wird bei einem Gelenkkopf der eingangs genannten Art neuerungsgemäß dadurch gelöst, daß die Laufschale axial über beide Seiten des Gehäuses vorsteht und in die Außenfläche der überstehenden Abschnitte je eine ringförmige Nut zur Aufnahme des äußeren Endrings je einer Dichtmanschette eingearbeitet ist.In a joint head of the type mentioned at the outset, this object is achieved according to the invention in that the running shell extends axially over protrudes both sides of the housing and in the outer surface of the protruding portions each have an annular groove for receiving the outer end ring is each incorporated a sealing collar.
Dadurch ergibt sich eine wesentlich vereinfachte Herstellung des Gelenkkopfes, da keine besonderen Nutringe oder Kontermuttern hergestellt und eingepaßt werden müssen, sondern lediglich jeweils eine Nut in die überstehenden Abschnitte der Laufschale eingefräst werden muß.This results in a significantly simplified production of the joint head, since there are no special groove rings or lock nuts must be produced and fitted, but only one groove in each of the protruding sections of the barrel shell must be milled.
Bei einer vorteilhaften Ausgestaltung der Neuerung können die eingearbeiteten Nuten gleichzeitig zur Festlegung der Laufschale im Gehäuse ausgenützt werden, indem jede Nut in Richtung zur gegenüberliegenden Nut hin verbreitert ist und im verbreiterten Teil einen eingebördelten Rand des Gehäuses aufnimmt. Dadurch wer den sonst notwendige Abfasungen, Kontermuttern oder dergleichenIn an advantageous embodiment of the innovation, the incorporated grooves can be used at the same time to fix the barrel shell in the housing can be exploited by placing each groove in the direction of the opposite one Groove is widened and receives a crimped edge of the housing in the widened part. Thereby who the otherwise necessary chamfers, lock nuts or the like

Anhand der Figuren wjrd ein Ausführungsbeispiel der Neuerung näher erläutert. Es zeigt:An exemplary embodiment of the innovation is shown on the basis of the figures explained in more detail. It shows:
Fig. 1 einen Axialschnitt durch den Gelenkkopf und Fig. 2 ein vergrößertes Detail aus Fig. 1.1 shows an axial section through the joint head and FIG. 2 shows an enlarged detail from FIG. 1.
Bei der dargestellten Ausführungsform weist das allgemein mit bezeichnete Gehäuse des Gelenkkopfes einen kreisförmigen Ausschnitt 12 auf, in welchen eine ringförmige Laufschale 14 eingepaßt ist. Die Laufschale 14 steht auf beiden Seiten axial über das Gehäuse 10 vor. In die Außenflächen der überstehenden Abischnitte 16 ist je eine ringförmige Nut 18 eingearbeitet, die zur Aufnahme des äußeren Endrings 20 einer Dichtungsmanschette 22 dient.In the embodiment shown, the housing, generally designated by, of the joint head has a circular cutout 12, in which an annular barrel shell 14 is fitted is. The running shell 14 protrudes axially on both sides the housing 10 in front. In the outer surfaces of the protruding sections 16 each has an annular groove 18 incorporated, which is used to receive the outer end ring 20 of a sealing collar 22 is used.
In der Laufschale 14 ist der Innenring 24 gelagert, in dessen Bohrung die bei der dargestellten Ausführungsform aus zwei Hälften bestehende Bohrungsbüchse 26 mit Preßsitz eingepaßt ist. In die Außenseite der Bohrungsbüchse 26 sind Nutringe 28 drehbar eingesetzt, die jeweils zur Aufnahme des inneren Endrings 30 der Dichtmanschetten 22 dienen.In the running shell 14, the inner ring 24 is mounted, in which Bore which, in the illustrated embodiment, consists of two halves bore bushing 26 fitted with a press fit. In the outside of the bore sleeve 26 are U-rings 28 rotatably inserted, each for receiving the inner end ring 30 of the Sealing sleeves 22 are used.
In der vergrößerten Detaildarstellung der Fig. 2 ist zu sehen, daß jede Nut 18 in axialer Richtung zur gegenüberliegenden Nut 18 hin (die allerdings in Fig. 2 nicht zu sehen ist) eine Verbreiterung 32 aufweist. Nahe dem inneren Rand 34 des Gehäuses 10 ist eine ringförmige Kerbe 36 vorgesehen, so daß der innere Rand 34 durch Einbördeln in die gestrichelt gezeichnete Lage 34' gebracht werden kann, in der er in der Verbreiterung 32 der ringförmigen Nut 18 aufgenommen ist. Dadurch dient die Nut 18 gleichzeitig zur Festlegung der neuerungsgemäßen Laufschale 14 am Gehäuse 10 des Gelenkkopfes.In the enlarged detail view of FIG. 2 it can be seen that each groove 18 is in the axial direction to the opposite groove 18 (which, however, cannot be seen in FIG. 2) has a widening 32. Near the inner edge 34 of the housing 10 an annular notch 36 is provided so that the inner edge 34 by crimping into the dashed line position 34 ' can be brought, in which it is received in the widening 32 of the annular groove 18. The groove 18 thereby serves at the same time to define the running shell 14 according to the innovation on the housing 10 of the joint head.
