Abstract

A conical spiral mixer with a conically tapered mixer container, includes a mixing spiral that moves parallel to the conical inner wall of the mixing container, the lower end of the mixing spiral extending through an opening in the container bottom below which is a swingable and pivotable bearing. The sealing between the shaft of the mixing spiral and the opening in the container bottom, is provided by means of a spherical sealing body pivotably supported on the shaft of the mixing spiral, but at an angle to the axis of the mixing container. The sealing body takes part in the swing movement of the shaft of the mixing spiral, but not however in its pivoting or spinning movement.

Description

Die Erfindung betrifft einen Konus-Schneckenmischer nach dem Oberbegriff des Patentanspruchs 1. Ein derartiger Konus-Schneckenmischer ist mit der auf den gleichen Anmelder zurückgehenden deutschen Offenlegungsschrift 32 45 935.1 bekannt geworden. Merkmal dieses Schneckenmischers ist, daß der Antrieb der Mischschnecke von einem unterhalb des Mischbehälters angeordneten Antrieb erfolgt, der über ein Kreuzgelenk, welches außerhalb des Produktraumes angeordnet ist, die Mischschnecke auf Drehung antreibt. Zur Abdichtung des Durchgriffs der Welle der Mischschnecke durch die öffnung im Boden des Mischbehälters ist hierbei ein sphärischer Dichtungskörper vorgesehen, wie er prinzipiell durch den Gegenstand der DE-OS 1 956 oo7 oder der DE-OS 2 701 799 bekannt geworden ist.The invention relates to a cone screw mixer according to the preamble of claim 1. Such a cone screw mixer has become known with the German patent application 32 45 935.1, which goes back to the same applicant. A feature of this screw mixer is that the mixing screw is driven by a drive which is arranged below the mixing container and which drives the mixing screw to rotate via a universal joint which is arranged outside the product space. To seal the passage of the shaft of the mixing screw through the opening in the bottom of the mixing container, a spherical sealing body is provided, as is known in principle from the subject matter of DE-OS 1 956 oo7 or DE-OS 2 7 0 1 799.

Nachteil der beiden letztgenannten Ausführungsformen ist jedoch, daß der sphärische Dichtungskörper an der Drehung der Mischschneckenwelle beteiligt ist und daß es deshalb zu einem schnellen Verschleiß der gehäuseseitigen oder der wellenseitigen Dichtungen kommt.A disadvantage of the latter two embodiments, however, is that the spherical sealing body is involved in the rotation of the mixing screw shaft and that there is therefore rapid wear on the housing-side or the shaft-side seals.

Hier hat die auf den gleichen Erfinder zurückgehende deutsche Patentanmeldung P 32 45 935 Abhilfe geschaffen, indem der sphärische Dichtungskörper drehbar auf der Mischschneckenwelle gelagert war, so daß er im wesentlichen still steht und nur die Taumelbewegungen der Mischschneckenwelle mitmacht, wenn sich die Mischschneckenwelle parallel zur Innenwand des konischen Mischbehälters bewegt.Here the German patent application P 32 45 935, which goes back to the same inventor, has remedied this by the spherical sealing body being rotatably mounted on the mixing screw shaft, so that it stands essentially still and only takes part in the wobbling movements of the mixing screw shaft when the mixing screw shaft is parallel to the inner wall of the conical mixing container moves.

Mit der gezeigten drehbaren Lagerung des sphärischen Dichtungskörpers auf der Welle der Mischschnecke war jedoch noch keine Zuführung von Schmiermittel in die Lager zwischen dem Dichtungskörper und der Welle der Mischschnecke möglich, weil bei bestimmten Produktzusammensetzungen im Mischbehälter und unter gewissen Umständen es vorkommen konnte, daß der Dichtungskörper noch drehend mit der Umdrehung der Mischschnecke mitgenommen wurde. Die Erfindung hat sich deshalb die Aufgabe gestellt, einen Konus-Schnekkenmischer mit sphärischem Dichtungskörper in der Bodenöffnung nach dem Gegenstand der DE-OS 32 45 935 so weiterzubilden, daß eine öl-, oder Kühl- oder Schmiermittelzufuhr in das Lager zwischen der Welle der Mischschnecke und dem Dichtungskörper möglich ist.With the shown rotatable bearing of the spherical Sealing body on the shaft of the mixing screw, however, it was not yet possible to supply lubricant to the bearings between the sealing body and the shaft of the mixing screw, because with certain product compositions in the mixing container and under certain circumstances it could happen that the sealing body still rotated with the rotation of the mixing screw was taken away. The invention has therefore set itself the task of developing a cone screw mixer with a spherical sealing body in the bottom opening according to the subject of DE-OS 32 45 935 so that an oil, or coolant or lubricant supply into the bearing between the shaft of the mixing screw and the sealing body is possible.

Zur Lösung der gestellten Aufgabe ist die Erfindung dadurch gekennzeichnet, daß der Dichtungskörper drehfest , jedoch im Winkel zur Achse des Mischbehälters schwenkbar an einem gehäusefesten Flansch des Mischbehälters gelagert ist.To achieve the object, the invention is characterized in that the sealing body is non-rotatably, but pivotable at an angle to the axis of the mixing container on a flange of the mixing container fixed to the housing.

Wesentliches Merkmal der Erfindung ist also, daß der Dichtungskörper nach der Erfindung zwar drehfest arretiert ist, trotzdem aber die Taumelbewegungen der Mischschneckenwelle mitmachen kann. Durch die drehfeste Arretierung des Dichtungskörpers nimmt dieser nicht mehr an der Drehung der Mischschneckenwelle teil und es ist deshalb möglich, die oben genannten Schmier- und Kühlmittel über flexible Schläuche in das Lager zwischen dem Dichtungskörper und der Mischschneckenwelle einzuführen. Dadurch wird die Lebensdauer des Lagers wesentlich verlängert und trotzdem eine hohe Betriebssicherheit beibehalten, denn nachdem die gesamte Anordnung außerhalb des Mischbehälters angeordnet ist, kann eine Verschmutzung des Produktes im Mischbehälter durch aus dem Lager austretendes Schmier-oder Kühlmittel nicht stattfinden.An essential feature of the invention is therefore that the sealing body according to the invention is locked in a rotationally fixed manner, but can nevertheless take part in the wobbling movements of the mixing screw shaft. Due to the rotationally fixed locking of the sealing body, it no longer participates in the rotation of the mixing screw shaft and it is therefore possible to introduce the abovementioned lubricants and coolants into the bearing between the sealing body and the mixing screw shaft via flexible hoses. This significantly extends the life of the bearing and still maintains high operational reliability, because after the entire arrangement has been arranged outside the mixing container, the product in the mixing container cannot be contaminated by lubricant or coolant escaping from the bearing.

In einer bevorzugten Ausführungsform der vorliegenden Erfindung ist vorgesehen, daß die Verdrehungssicherung und Schwenklagerung des Dichtungskörpers durch ein Schwenkgestänge gebildet ist, dessen zueinander parallele Schwenkachsen senkrecht zur Drehachse der Mischschnecke angeordnet sind.In a preferred embodiment of the present invention it is provided that the anti-rotation and swivel mounting of the sealing body is formed by a swivel linkage, the mutually parallel swivel axes of which are arranged perpendicular to the axis of rotation of the mixing screw.

Dadurch, daß man die Schwenkachsen senkrecht zur Drehachse der Mischschnecke anordnet, wird die geforderte Verdrehungssicherung erreicht (Anspruch 2).By arranging the swivel axes perpendicular to the axis of rotation of the mixing screw, the required anti-rotation is achieved (claim 2).

Eine besonders einfache Ausführung des Schwenkgestänges ergibt sich nach dem Gegenstand des Anspruches 3 dadurch, daß das Schwenkgestänge aus einem ersten Schwenkarm besteht, dessen eines Ende in einer ersten gehäusefesten Schwenkachse drehbar gelagert ist und dessen anderes Ende über eine zweite Schwenkachse mit dem einen Ende eines zweiten Schwenkarmes verbunden ist, dessen anderes Ende über eine dritte Schwenkachse schwenkbar am Dichtungskörper angreift. Es wird also ein aus zwei Schwenkarmen bestehendes Schwenkgestänge vorgeschlagen, welches den erforderlichen Hub des Dichtungskörpers gewährleistet und trotzdem verhindert, daß der Dichtungskörper verdreht werden kann.A particularly simple design of the swivel linkage results from the fact that the swivel linkage consists of a first swivel arm, one end of which is rotatably mounted in a first swivel axis fixed to the housing and the other end of which is connected to the one end of a second via a second swivel axis Swivel arm is connected, the other end pivotally engages on the sealing body via a third pivot axis. A pivot linkage consisting of two pivot arms is therefore proposed, which ensures the required stroke of the sealing body and nevertheless prevents the sealing body from being rotated.

Hierbei wird es nach dem Gegenstand des Anspruches 4 bevorzugt, wenn die Länge des Schwenkgestänges einstellbar ist, um das Schwenkgestänge unterschiedlichen Hüben des Dichtungskörpers anzupassen , wenn die gesamte Anordnung beispielsweise in einen Mischbehälter mit anders geneigten konischen Wänden eingebaut werden soll.It is preferred according to the subject matter of claim 4 if the length of the swivel linkage is adjustable in order to adapt the swivel linkage to different strokes of the sealing body if the entire arrangement is to be installed, for example, in a mixing container with differently inclined conical walls.

Nach dem Gegenstand des Anspruches 5 wird es hierbei ferner bevorzugt, wenn das Schwenkgestänge in Form eines Kreuzgelenkes am Dichtungskörper angreift, weil damit die Kippbewegungen des Dichtungskörpers direkt in diesem Kreuzgelenk stattfinden, während der restliche Teil des Schwenkgestänges lediglich eine Höhenverstellung gewährleistet.According to the subject matter of claim 5, it is further preferred if the swivel linkage acts in the form of a universal joint on the sealing body, because the tilting movements of the sealing body take place directly in this universal joint, while the rest Part of the swivel linkage only ensures height adjustment.

Der Erfindungsgegenstand der vorliegenden Erfindung ergibt sich nicht nur aus dem Gegenstand der einzelnen Patentansprüche, sondern auch aus der Kombination der einzelnen Patentansprüche untereinander.The subject matter of the present invention results not only from the subject matter of the individual patent claims, but also from the combination of the individual patent claims with one another.

Nach Figur 1 ist in einem konisch in Richtung zum Bodenbereich zulaufenden Mischbehälter 88 eine Mischschnecke 7o angeordnet, welche sich mit der Drehzahl n1 um die Achse 11o dreht und welche sich mit der Drehzahl n2 um die Behälterachse 100 schwenkt. Hierzu ist die Mischschnecke 7o in ihrem oberen Bereich am freien Ende eines Führungsarmes 71 angeordnet, welcher mit der Drehzahl n2 über einen Motor 95 und ein Getriebe 72 angetrieben wird. Am Behälterdeckel sind entsprechende Abdichtungen 73 vorgesehen, um ein Austreten des Produktmediums aus dem Produktraum 8o zu verhindern.According to FIG. 1, a mixing screw 7o is arranged in a mixing container 88 which tapers conically towards the bottom area and which rotates about the axis 11o at the speed n1 and which pivots about the container axis 100 at the speed n2. For this purpose, the mixing screw 7o is arranged in its upper region at the free end of a guide arm 71 which is driven at a speed n2 via a motor 95 and a gear 72. Corresponding seals 73 are provided on the container lid in order to prevent the product medium from escaping from the product space 8o.

Die bodenseitige Lagerung der Mischschnecke 7o erfolgt in der in Figuren 2 und 3 gezeigten Weise mit Hilfe eines Kreuzgelenks 27, wobei die Mischschnecke ihren Drehantrieb (Antrieb um die Achse 110) über eine Gelenkwelle 34 erhält, welche in einer Hohlwelle 32 gelagert ist, an deren Ende eine Laterne 62 angeflanscht ist, an deren unterem Ende der Getriebemotor 65 ansetzt.The bottom support of the mixing screw 7o takes place in the embodiment shown in Figures 2 and 3, using a universal joint 27, wherein the mixing screw receives its rotary drive (drive about the axis 11 0) via an articulated shaft 34, which is mounted in a hollow shaft 32 on the end of which is flanged to a lantern 62, at the lower end of which the geared motor 65 is attached.

Gemäss Figur 2 ist die Msichschnecke 7o mit einem Kupp-lungsstück 29 mit Innengewinde fest verschweisst. In dieses Kupplungsstück 29 ist ein Einschraubbolzen 1 so eingeschraubt, daß sich das Gewinde im Betriebsfall von selbst anzieht; d.h. je nach Drehrichtung der Mischschnecke 7o ein Rechts- oder Linksgewinde verwendet wird.According to Figure 2, the Msichschnecke 7o is welded firmly with a Ku p p-lung piece 29 with internal thread. In this coupling piece 29, a screw-in bolt 1 is screwed in such a way that the thread automatically tightens during operation; that is, depending on the direction of rotation of the mixing screw 7o, a right-hand or left-hand thread is used.

Anstelle des Kupplungsstückes 29 mit Innengewinde kann eine drehfeste Verbindung von Kupplungsstück 29 und Einschraubbolzen 1 auch mit einer Paßfederverbindung oder einem Abscherstift durchgeführt werden.Instead of the coupling piece 29 with an internal thread, a rotationally fixed connection of the coupling piece 29 and screw-in bolt 1 can also be carried out with a feather key connection or a shear pin.

Auf dem Einschraubbolzen 1 ist eine Buchse 2 aufgezogen. Das Wälzlager 6 sowie die Buchse 7 werden spielfrei mittels des Seegerringes 8 auf dem Einschraubbolzen 1 angebracht.A bushing 2 is mounted on the screw-in bolt 1. The roller bearing 6 and the bushing 7 are attached to the screw bolt 1 without play by means of the circlip 8.

Der Einschraubbolzen 1 wird mittels Schrauben 25 drehfest mit dem Oberteil des Kreuzgelenks 27 verbunden. Das Kreuzgelenk-Unterteil wird wiederum mit Schrauben 28 drehfest mit der Gelenkwelle 34 verschraubt.The screw-in bolt 1 is connected in a rotationally fixed manner to the upper part of the universal joint 27 by means of screws 25. The lower joint part is in turn screwed with screws 28 to the drive shaft 34 in a rotationally fixed manner.

über den Einschraubbolzen 1 mit der Buchse 2, dem Wälz- lager 6, der Buchse 7 und dem Seegerring 8 sowie über das Kreuzgelenk 27 wird ein halbkugeliger Dichtungskörper 4 mit eingelassenen Dichtungen 3 geschoben und mittels eines Flansches 1o mit Dichtung 9 sowie Beilagringen 5 axial und radial gesichert. Eine Abdichtung erfolgt über den O-Ring 56. Die Verschraubung erfolgt über die Schrauben 59. Eine Nachschmierung der Lager erfolgt über die Blindschraube 12 der Dichtscheibe 13 oder über eine ständige Zuführung von Schmier- und Kühlmittel über einen nicht näher dargestellten flexiblen Schlauch, der anstelle der Schraube 12 angeordnet ist. Eine zusätzliche Abdichtung ist über den O-Ring 11 gewährleistet. Die Konstruktion und Montage muß gewährleisten, daß der Mittelpunkt des Kreuzgelenks 27 sowie der Mittelpunkt der Dichtungsglocke 4 ein und derselbe Punkt sind. Hierbei kann die Mischschneckenwelle bis zum 25° schräg zur vertikalen Achse stehen.via the screw-in bolt 1 with the sleeve 2, the W älz- bearing 6, the bushing 7 and the retaining ring 8, as well as the universal joint 27, a hemispherical sealing member 4 is pushed with embedded gaskets 3 and axially by means of a flange 1o with seal 9, and Beilagringen 5 and secured radially. Sealing takes place via the O-ring 56. The screw connection takes place via the screws 59. The bearings are relubricated via the blind screw 12 of the sealing disk 13 or via a constant supply of lubricant and coolant via a flexible hose, not shown, which instead the screw 12 is arranged. An additional seal is ensured via the O-ring 11. The construction and assembly must ensure that the center of the universal joint 27 and the center of the sealing bell 4 are one and the same point. The mixing screw shaft can be inclined up to 25 ° to the vertical axis.

Auf der Gelenkwelle 34 wird eine Buchse 31 (Wellenschonhülse) drehfest aufgezogen. Weiterhin werden die Lager-Innenringe der Lager 36 sowie das Rohr 33 auf die Gelenkwelle 34 aufgezogen und mit dem Seegerring 38 gesichert. Die Gelenkwelle 34 ist mit verschiedenen Zentrierungen für die Lager sowie einem Gewindezapfen 46 mit einem Vierkant versehen.A bushing 31 (shaft sleeve) is rotatably mounted on the cardan shaft 34. Furthermore, the bearing inner rings of the bearings 36 and the tube 33 are drawn onto the cardan shaft 34 and secured with the circlip 38. The cardan shaft 34 is provided with different centerings for the bearings and a threaded pin 46 with a square.

Das Lagergehäuse besteht aus einem Rohrgehäuse 18, einem Gegenflansch 52, sowie einer Hohlwelle 32, welche miteinander verschweisst sind. Im Rohrgehäuse 18 sind mehrere Montage- und Kontroll- öffnungen angeordnet, welche mit mehreren, am Umfang des Lagergehäuses angeordneten Deckeln 21, den Schrauben 60 und den Dichtringen 19 verschlossen werden.The bearing housing consists of a tubular housing 18, a counter flange 52 and a hollow shaft 32, which are welded together. A plurality of assembly and control openings are arranged in the tubular housing 18, with several on the circumference of the bearing housing arranged covers 21, the screws 60 and the sealing rings 19 are closed.

In der Hohlwelle 32 sind die Außenringe des Lagers 36 eingeschoben und werden mit den Seegerringen 37 gegen axiales Verschieben gesichert. Der Lagerflansch 43 sowie das zweiseitig wirkende Axiallager 40 werden in die Hohlwelle 32 eingeschoben. Der Lagerflansch 43 mit dem O-Ring 42 wird nun in die Bohrung der Hohlwelle 32 bzw. über den Außenring des Lagers 40 geschoben und mit den Schrauben 60 fest mit der Hohlwelle 32 verbunden. Der Lagerflansch 39 muß fest am Seegerring 37 anstehen und das Axiallager 40 muß axial nahezu spielfrei eingestellt sein. Weiterhin werden in die Hohlwelle 32 der Wellendichtring 30 sowie der Schmiernippel 58 eingepresst.The outer rings of the bearing 36 are inserted into the hollow shaft 32 and are secured with the circlips 37 against axial displacement. The bearing flange 43 and the double-acting axial bearing 40 are inserted into the hollow shaft 32. The bearing flange 43 with the O-ring 42 is now pushed into the bore of the hollow shaft 32 or over the outer ring of the bearing 40 and firmly connected to the hollow shaft 32 with the screws 60. The bearing flange 39 must be in contact with the circlip 37 and the axial bearing 40 must be set axially with almost no play. Furthermore, the shaft sealing ring 30 and the lubricating nipple 58 are pressed into the hollow shaft 32.

Es wird dann sonach die Gelenkwelle 34 eingeschoben. Durch die Spannscheibe 41, den Federring 47 und die Gewindemutter 48 wird die Gelenkwelle 34 fest mit dem Axiallager 40 verbunden.The propeller shaft 34 is then inserted. The drive shaft 34 is firmly connected to the thrust bearing 40 by means of the clamping disk 41, the spring ring 47 and the threaded nut 48.

Die Verbindung der Mischschnecke 70 mit dem Einschraubbolzen 1 wird durch Drehen des Vierkants der Gelenkwelle 34 vorgenommen, wobei das Kupplungsstück 29 sich auf das Gewinde des Einschraubbolzens 1 aufschraubt. Dies kann ohne Demontage der Lageranordnung gemacht werden. Nach Durchführung dieser Arbeiten wird der Lagerflansch 43 mit dem Deckel 45 verschlossen.The connection of the mixing screw 70 with the screw-in bolt 1 is carried out by turning the square of the drive shaft 34, the coupling piece 29 screwing onto the thread of the screw-in bolt 1. This can be done without disassembling the bearing assembly. After performing this work, the bearing flange 43 is closed with the cover 45.

Das Lagergehäuse wird mittels Gewindebolzen 55, Muttern 54 und Federringen 53 mit dem Behälterboden 17 drehfest verschraubt und mit einem O-Ring 26 abgedichtet.The bearing housing is rotatably screwed to the container bottom 17 by means of threaded bolts 55, nuts 54 and spring washers 53 and sealed with an O-ring 26.

Die Abdichtung zwischen dem Dichtungskörper 4 und dem Behälterboden 17 wird mit einem Dichtflansch 14, einem Stellflansch 15 mit O-Ring 16 durchgeführt.The seal between the sealing body 4 and the container bottom 17 is with a sealing flange 14, a Adjusting flange 15 with O-ring 16 performed.

Der Werkstoff des Dichtflansches 14 kann aus Teflon (eingetragenes Warenzeichen für DuPont) oder einem anderen Gleitlager-Werkstoff sein. Der Werkstoff des Dichtungskörpers 4 muß aus einem gehärteten, plattierten oder Edelstahlmaterial oder einem anderen, zum Dichtflansch 14 passenden, Werkstoff sein.The material of the sealing flange 14 can be made of Teflon (registered trademark for DuPont) or another plain bearing material. The material of the sealing body 4 must be made of a hardened, plated or stainless steel material or another material that matches the sealing flange 14.

Der Dichtflansch 14 hat einen inneren Spülring 49, welcher mit einer Einlaß- bzw. Ablaßbohrung, welche durch den Stellflansch 15 durchgebohrt ist, versehen ist.The sealing flange 14 has an inner flushing ring 49, which is provided with an inlet or outlet bore, which is drilled through the adjusting flange 15.

Die Einlaß- und Ablaßbohrung des Stell- und Dichtflansches 14,15 ist an derselben Stelle, wie die Einlaß- bzw. Ablaßbohrung im Behälterboden 17.The inlet and outlet bores of the adjusting and sealing flange 14, 15 are at the same location as the inlet and outlet bores in the container bottom 17.

Der Stellflansch 15 ist mit einem Schraubbolzen mit Gegenmutter gegen Verdrehung gesichert. Im Stellflansch 15 sind mehrere federbelastete Vorspannschrauben 24 mit Kontermutter 23 und den Federn 22 angebracht. Diese Vorspannschrauben 24 drücken den Stellflansch 15 mit dem Dichtflansch 14 nach unten gegen die Dichtungsfläche des Dichtungskörpers 4.The adjusting flange 15 is secured against rotation with a screw bolt with a lock nut. In the control flange 15 a plurality of spring-loaded pre- p 24 screws with lock nut 23 and the springs 22 are attached. These preload screws 24 press the adjusting flange 15 with the sealing flange 14 downward against the sealing surface of the sealing body 4.

Der in Figur 2 gezeigte Spülring 49 ermöglicht eine Reinigung der Dichtungsglocke 4 bzw. des Dichtflansches 14 ohne Demontage der Lagerung. Weiterhin kann dieser Spülring 49 als Kühlung für den Dichtungskörper 4 verwendet werden.The flushing ring 49 shown in FIG. 2 enables the sealing bell 4 or the sealing flange 14 to be cleaned without dismantling the bearing. Furthermore, this flushing ring 49 can be used as cooling for the sealing body 4.

Der Luftraum zwischen dem Dichtflansch 14 und dem Dichtungskörper 4 und dem Lagergehäuse 18,52,32 kann als Isolierschicht aufgefasst werden. Außerdem kann das Kreuzgelenk 27 und die abdichtenden Kugelteile von innen mit Sperrflüssigkeit bzw. Kühlflüssigkeit oder einem Gas gespült werden. Hierbei werden jeweils ein Anschluß für Ein- und Ablauf der Kühlflüssigkeit im Deckel 21 gemacht.The air space between the sealing flange 14 and the sealing body 4 and the bearing housing 18, 52, 32 can be regarded as an insulating layer. In addition, the universal joint 27 and the sealing ball parts can be sealed from the inside with sealing liquid or cooling liquid or a gas be rinsed. In this case, a connection is made for the inlet and outlet of the coolant in the cover 21.

Das in den Figuren 3 und 4 gezeigte Schwenkgestänge 50 besteht aus einer mit dem gehäusefesten Flansch 20 verbundenen Montageplatte 81, in der schwenkbar über eine erste Schwenkachse 84 das eine Ende eines Schwenkarmes 82 drehbar gelagert ist.The pivot linkage 50 shown in FIGS. 3 and 4 consists of a mounting plate 81 connected to the flange 20 fixed to the housing, in which the one end of a pivot arm 82 is rotatably mounted via a first pivot axis 84.

Das andere Ende des Schwenkarmes 82 ist über eine zweite Schwenkachse 75 mit dem einen Ende eines zweiten Schwenkarmes 83 gelenkig verbunden, der seinerseits wiederum an seinem gegenüberliegenden, freien Ende über die dritte Schwenkachse 76 mit dem freien, vorderen Ende eines Bolzens 84 verbunden ist. Der Bolzen 84 ist Teil eines Kreuzgelenks 51,welches als Anschlußteil den Anschluß zur Unterseite des Dichtungskörpers 4 herstellt.The other end of the swivel arm 82 is articulated via a second swivel axis 75 to the one end of a second swivel arm 83, which in turn is in turn connected at its opposite, free end via the third swivel axis 76 to the free, front end of a bolt 84. The bolt 84 is part of a universal joint 51 which, as a connecting part, establishes the connection to the underside of the sealing body 4.

Der Bolzen 84 ist hierbei drehbar in einem senkrecht dazu verlaufenden Querbolzen 86 gelagert, der seinerseits wiederum drehbar in einer zum Bolzen 84 senkrechten Achse in einer Buchse 85 drehbar gelagert ist. Die Buchse 85 ist mit der Unterseite des Dichtungskörpers 4 fest verbunden.The bolt 84 is in this case rotatably mounted in a transverse bolt 86 running perpendicular thereto, which in turn is rotatably mounted in a bush 85 in an axis perpendicular to the bolt 84. The socket 85 is firmly connected to the underside of the sealing body 4.

Aus der Darstellung in Figur 3 und Figur 4 wird deutlich, daß der Dichtungskörper 4 nur noch Schwenkbewegungen durchführt, wobei das Schwenkgestänge 5o in gestreckter Lage seine in gestrichelter Darstellung eingezeichnete Position nach Figur 3 einnimmt.It is clear from the illustration in FIG. 3 and FIG. 4 that the sealing body 4 only carries out pivoting movements, the pivot linkage 50 in its extended position assuming its position shown in broken lines in FIG. 3.

Bei Verschwenkung des Dichtungskörpers 4 in seine Stellung 4' nehmen daher die Schwenkarme 82,83 ihre Stellungen 82',83 ein.When the sealing body 4 is pivoted into its position 4 ', the pivot arms 82, 83 therefore assume their positions 82', 83.

Dem Dichtflansch 14 gegenüberliegend sind jeweils ein gehäuseseitiger Dichtflansch 78 angeordnet, der an einem Lagerflansch 77 befestigt ist.Opposite the sealing flange 14, a housing-side sealing flange 78 is arranged in each case Bearing flange 77 is attached.

Die Figur 4 zeigt entsprechende Kippbewegungen des Dichtungskörpers 4, wobei dann die Buchse 5 ihre Stellungen 85' bzw. 85" einnimmt.FIG. 4 shows corresponding tilting movements of the sealing body 4, in which case the bushing 5 assumes its positions 85 'or 85 ".

Die beschriebene Schwenklagerung des Dichtungskörpers ist ein wesentlicher Vorteil gegenüber dem Stand der Technik, denn vorher mussten die Reibkräfte zwischen dem Dichtungskörper und dem Dichtflansch 14 immer größer sein, als die durch die Wälzlager 6 und durch die Dichtungen 3 und 9 verursachten Reibkräfte.The described pivot bearing of the sealing body is a significant advantage over the prior art, because previously the frictional forces between the sealing body and the sealing flange 14 had to be always greater than the frictional forces caused by the roller bearings 6 and by the seals 3 and 9.
