Abstract

The intention is, with the aid of a device on discs, in particular seals, which prior to installation are stacked resting against one another and are installed in machine components, e.g. rolling bearings, by automatic equipment, to ensure that in each case only one seal is taken. The solution consists in the fact that, to ensure unproblematic removal of individual discs at least on one of the front sides of the seals, raised portions (6) or depressions are formed in such a way that the only contacts are point or line contacts. <IMAGE>

Description

Vorrichtung an Scheiben inabesond-ereDevice on discs in particular

Dichtungen Die Erfindung bezieht sich auf eine Vorrichtung nach dem Oberbegriff des ersten Anspruchs.Seals The invention relates to a device according to the Preamble to the first claim.

Es sind automatische Einrichtungen in Benutzung, mit denen Dichtungen in z.B. Wälzlager eingebaut werden. Die Dichtungen werden dabei flächig aufeinander anliegend, z. B. in Kunststoffschläuchen verpackt angeliefert. Wenn sie nun vom Stapel automatisch entnommen werden sollen, ergeben sich aber Schwierigkeiten, denn sie haften meist aneinander. Von der automatischen Einrichtung werden daher statt einer Dichtung oft mehrere entommen. Damit ist aber eine automatische Montage nicht mehr möglich.There are automatic devices in use with which seals be installed in e.g. rolling bearings. The seals are flat on top of each other attached, e.g. B. delivered packed in plastic tubes. If you now from Stack should be removed automatically, but difficulties arise because they usually stick to one another. The automatic device will therefore take place often several taken from one seal. But that does not mean automatic assembly more is possible.

Es ist daher Aufgabe der Erfindung Dichtungen so weiter zu verbessern, daß von einer automatischen Einrichtung bei der Abnahme von einem Stapel mit Sicherheit immer nur eine Dichtung erfaßt wird.It is therefore the object of the invention to further improve seals, that of an automatic device for the removal of a batch with certainty only one seal is ever recorded.

Die Lösung wird im kennzeichnenden Teil des ersten Anspruchs dargelegt. Die Anspr. 2 bis 4 enthalten spezielle Ausgestaltungen.The solution is set out in the characterizing part of the first claim. The claim 2 to 4 contain special designs.

Dadurch, daß die aneinander anliegenden Dichtungen Vorspriinge besitzen, ist ihre Erfassung durch Entnahmeeinrichtung einfacher. Wegen der Punkt-oder Linienberührung ist zusätzlich immer sichergestellt, daß nur jeweils eine Dichtung erfaßt wird.Due to the fact that the seals resting against one another have projections, it is easier to record them using the extraction device. Because of point or line contact it is also always ensured that only one seal is detected at a time.

Ein Aneinanderhaften von mehreren Dichtungen wird vermieden, da keine flächenhafte Anlage vorhanden ist.A sticking together of several seals is avoided because none extensive facility is available.

Aus der DE-AS 10 73 0Z+7 sind zwar Dichtscheiben bekannt die Vorsprünge aufweisen, hier besitzen sie aber Abstützfunktionen und iiber ihren Einbau wird nichts as{esarft.From DE-AS 10 73 0Z + 7 sealing washers are known, the projections have, but here they have support functions and their installation is determined nothing as {arft.

Damit ein die Entnahme erschwerendes Verkippen der erfindungsgemäßen Dichtscheiben vermieden wird, ist es zweckmäßig, die Brhebungen oder Vertiefungen im radial äußeren Bereich vorzusehen. Aus Fertigungsgründen ist es weiterhin vorzuziehen, die Erhebungen oder Vertiefungen einstückig an den Kunststoffteilen vorzu-ehen. Die Erhebungen ergeben außerdem dann mit t größerer Sicherheit eine ftinkt- oder Linienberührung, wenn sie im Querschnitt die Form eines Dreieckes besitzen.Thus, the removal of the inventive tilting, which makes the removal more difficult Sealing washers is avoided, it is advisable to remove the raised areas or depressions to be provided in the radially outer area. For manufacturing reasons, it is still preferable Vorzu-ehen the elevations or depressions in one piece on the plastic parts. The surveys then also result in an instinct or with greater certainty Line contact if they have the shape of a triangle in cross-section.

Die Erfindung wird an Hand einer Figur näher erläutert. Diese zeigt einen Teilquerschnitt durch zwei aneinander anliegenden Dichtungen in Form von Schleuderscheiben.The invention is explained in more detail with reference to a figure. This shows a partial cross-section through two adjacent seals in the form of centrifugal disks.

Jede der Schleuderscheiben 1 und 2 besteht aus einer Verstärkungseinlage 3, die e mit einem Kunststoffteil 4 versehen ist. Letzterer besitzt an einem i:rlde Haltelippen 5.Each of the slinger discs 1 and 2 consists of a reinforcement insert 3, which is provided with a plastic part 4. The latter owns an i: rlde Retaining lips 5.

kür die automatische Einbaueinrichtung wichtig sind die an jeder Schleuderscheibe 1 und 2 angebrachten Erhebungen 6, die im Querschnitt eine dreieckige Form haben. Da die Spitze 7 der Schleuderscheibe 1 nur Linienberührung mit der ihr gegenüberliegenden Stirnseite 8 der anderen Schleuderscheibe 2 besitzt, wird ein Aneinanderhaften der beiden Schleuderscheiben 1 und 2 vermieden. Da weiterhin auch alle anderen Scheiben des jewelligen Stapels in gleicher Weise aneinander anliegen, ist eine Einzelentnahme durch die Einbaueinrichtung sichergestellt.what is important for the automatic installation device are those on each centrifugal disc 1 and 2 attached elevations 6, which have a triangular shape in cross section. Since the tip 7 of the centrifugal disk 1 only makes line contact with the one opposite it Has the end face 8 of the other centrifugal disk 2 is a Sticking together the two centrifugal disks 1 and 2 avoided. There continue to be all the other disks of the respective stack rest against each other in the same way, is a single removal ensured by the installation device.
