Description
Die Ei-finduiigrbetrifft eine Vorrichtung, die zum Ausbauen von Wellendichtungen aus ihrem Sitz im Maschinengehäuse bestimmt ist. Man hat bisher diese Dichtungen nur dadurch ausbauen können, daß man sie mit einem Werkzeug nach der Art eines Meißels od. dgl. herausgeschlagen hat, wobei die Dichtungen in der Regel mehr oder weniger vollständig zerstört wurden, so daß eine wiederholte Verwendung der gleichen Dichtung nicht möglich war.The egg finduiigr relates to a device that is used to remove shaft seals is determined from their seat in the machine housing. So far you have these seals can only be expanded by using a chisel-type tool Od. Like. Has knocked out, the seals usually more or less have been completely destroyed, so that repeated use of the same seal was not possible.
Gegenstand der Erfindung ist eine Vorrichtung zum Ausbauen von Wellendichtungen, die aus einem besonderen Werkzeug besteht, das mehrere zum Ansetzen am Rande der auszubauenden Dichtung geeignete Greifklauen besitzt und,in axialer Richtung abgezogen werden kann, wodurch auch die Dichtung als Ganzes von ihrem Sitz entfernt und aus dem Maschinengehäuse herausgenommen.wird. Beispielsweise kann dieses Werkzeug aus einer von Hand vierdrehbaren Schraubspindel und einem längs verschieblichen Kreuzstück bestehen, an welchem eine beliebige Zahl seitlich federnder Arme befestigt ist, deren Enden greiferartig ausgebildet sind und den umgebogenen Rand des Dichtungskäfigs hinter-, greifen können. Das Kreuzstück besitzt zu diesem Zwecke ein .Innengewinde, durch . welches die Schraubspindel hindurchgeführt ist; es ist außen je nach Zahl der Greiferarme, beispielsweise vier oder sechs, nach Art eines Mehreckes begrenzt. Die Greiferarme bestehen vorzugsweise aus federndem Stahl und sind an ihren Enden klauenartig nach außen gebogen. Durch Eindrücken der Arme von Hand können die Greifer unter den Griffrand des Dichtungsringes geschoben werden, so daß sie nach Freigabe unter Wirkung ihrer Federkraft diesen von hinten fassen. Wird nun das Ende der Schraubspindel gegen das Wellenende oder ein geeignetes Zwischenstück abgestützt und die Spindel gedreht, so werden die Greifer angezogen und ziehen die Dichtung von ihrem Sitz ab, ohne daß diese beschädigt wird. Die Dichtung kann also beliebig oft verwendet werden.The invention relates to a device for removing shaft seals, which consists of a special tool that allows several to be applied to the edge of the seal to be removed has suitable gripping claws and pulled off in the axial direction can be, whereby the seal as a whole removed from its seat and off removed from the machine housing. For example, this tool can be made from a screw spindle that can be turned four by hand and a longitudinally movable crosspiece exist, to which any number of laterally resilient arms are attached, the ends of which are designed like a gripper and the bent edge of the sealing cage be able to get behind. The cross piece has an internal thread for this purpose, by . which the screw spindle is passed through; it's outside depending on the number the gripper arms, for example four or six, limited in the manner of a polygon. The gripper arms are preferably made of resilient steel and are at their ends claw-like bent outwards. By pushing in the arms by hand, the grippers be pushed under the grip edge of the sealing ring, so that they can be released after release grasp it from behind under the action of its spring force. Will now be the end of the screw spindle supported against the shaft end or a suitable intermediate piece and the spindle rotated, the grippers are tightened and pull the seal from its seat without damaging it. The seal can be used as often as you like will.
Ein Ausführungsbeispiel eines Werkzeuges nach der Erfindung ist in der Zeichnung in schematischer Form dargestellt.An embodiment of a tool according to the invention is shown in the drawing shown in schematic form.
Fig. i ist ein axialer Längsschnitt durch das Werkzeug, Fig.2 ein Schnitt nach der Linie II-II in Fig. i. I it i ist ein Wellendichtungsring bezeichnet, dessen metallischer Käfig einen umgebördelten Rand 2 zum Angriff des Abziehwerkzeuges besitzt. 3 ist das Gehäuse, 'in -dessen Bohrung die Wellendichtung sitzt, .4 die durch den Dichtungsring abgedichtete Welle. Das Wellenende 5 trägt beispielsweise ein Außeiugewinde zum Aufsetzen einer Mutter od. dgl.Fig. I is an axial longitudinal section through the tool, Fig.2 a Section along the line II-II in Fig. I. I it i is a shaft sealing ring, whose metallic cage has a beaded edge 2 for attack by the pulling tool owns. 3 is the housing, 'in-whose bore the shaft seal sits, .4 the shaft sealed by the sealing ring. The shaft end 5 carries for example an external thread for placing a nut or the like.
Das Alizieliwerkzeug besteht aus der Schraubspindel6, dem auf dieser verschraubbaren Kreuzstück 7 und beispielsweise vier Greiferarmen 8 mit klauenartig nach außen gebogenen vorderen Enden g. Die Greiferarme sind durch Schrauben io mit dem Kreuzstück verbunden. Das hintere Ende der Spindel 6 trägt einen Griff oder Knebel ii oder auch ein Handrad od. dgl.. mittels dessen die Spindel gedreht werden kann.The Alizieli tool consists of the screw spindle6, the one on this screwable cross piece 7 and, for example, four gripper arms 8 with claw-like outwardly bent front ends g. The gripper arms are with screws io connected to the cross piece. The rear end of the spindle 6 carries a handle or Toggle ii or a handwheel or the like .. by means of which the spindle can be rotated can.
Wird das vordere Ende der Spindel gegen das Wellenende 5 abgestützt und die Spindel im richtigen Sinne gedreht, so wird das Kreuzstücks nach hinten bewegt und nimmt dabei die Arme 8 und über deren Klauen 9 auch die Wellendichtung i finit, so daß diese in sehr einfacher \\'eise völlig unliescliädigt aus ihrem Sitz herausgezogen wird.If the front end of the spindle is supported against the shaft end 5 and the spindle is rotated in the right direction, the cross piece is turned backwards moves and takes the arms 8 and via their claws 9 also the shaft seal i finite, so that in a very simple way it is completely unwoven from its The seat is pulled out.
