Abstract
Description
Die Erfindung geht aus von einer Dichtungseinheit nach dem Oberbegriff des Anspruchs 1. The invention is based on a sealing unit according to the preamble of claim 1.
Es ist eine einstückige Dichtung für Großlager aus Nitrilkautschuk bekannt. Vor der Montage der Dichtung liegt diese in aufgewickelter Form vor. Bei einer Montage der Dichtung werden zwei freie Enden der Dichtung auf Stoß geklemmt bzw. vulkanisiert. It is a one-piece seal for large bearings made of nitrile rubber known. Before the seal is installed, it is in wound-up form. When mounting the seal, two free ends of the seal are clamped or vulcanized in shock.
Die Aufgabe der Erfindung besteht insbesondere darin, eine gattungsgemäße Dichtungseinheit bereitzustellen, welche effektiv abdichtet, kostengünstig herstellbar und auf einfache Weise montierbar ist. Die Aufgabe wird erfindungsgemäß durch die Merkmale des Patentanspruchs 1 gelöst, während vorteilhafte Ausgestaltungen und Weiterbildungen der Erfindung den Unteransprüchen entnommen werden können.The object of the invention is, in particular, to provide a generic sealing unit which seals effectively, is inexpensive to produce and can be mounted in a simple manner. The object is achieved by the features of claim 1, while advantageous embodiments and modifications of the invention can be taken from the dependent claims.
Die Erfindung geht aus von einer Dichtungseinheit, insbesondere Großlagerdichtungseinheit zur Abdichtung eines Großlagers gegen Schmutz und gegen einen Austritt von Schmiermittel, mit einem ersten Dichtelement. The invention relates to a sealing unit, in particular large bearing sealing unit for sealing a large warehouse against dirt and against leakage of lubricant, with a first sealing element.
Es wird vorgeschlagen, dass die Dichtungseinheit wenigstens ein zweites Dichtelement aufweist, welches an dem ersten Dichtelement befestigt ist. Unter einem „Großlager“ soll insbesondere ein Lager verstanden werden, welches einen Innenring umfasst, der einen Innendurchmesser von wenigstens 300 mm aufweist. Mit einer erfindungsgemäßen Ausgestaltung kann eine effektive Abdichtung, eine kostengünstige Herstellbarkeit und eine einfache Montierbarkeit erreicht werden. Insbesondere kann erreicht werden, dass die Dichtungseinheit kostengünstiger ist als bei einer Ausbildung, bei der die Dichtungseinheit einstückig ausgebildet ist. Im Besonderen kann eine einfache Montage der Dichtungseinheit auf eine Welle erfolgen. It is proposed that the sealing unit has at least one second sealing element, which is fastened to the first sealing element. A "large warehouse" is to be understood in particular a bearing which comprises an inner ring having an inner diameter of at least 300 mm. With an embodiment according to the invention, an effective sealing, cost-effective manufacturability and ease of assembly can be achieved. In particular, it can be achieved that the sealing unit is less expensive than in an embodiment in which the sealing unit is formed in one piece. In particular, a simple assembly of the sealing unit can be done on a shaft.
Vorzugsweise sind die Dichtelemente formschlüssig und/oder kraftschlüssig aneinander befestigt, wodurch eine konstruktiv einfache Bauweise erreicht werden kann. Preferably, the sealing elements are positively and / or non-positively attached to each other, whereby a structurally simple construction can be achieved.
Ferner wird vorgeschlagen, dass wenigstens eines der Dichtelemente durch Drehen hergestellt ist. Dadurch können Deformationen im Abdichtungsbereich der Dichtungseinheit verursacht durch ein Aufgewickeltsein der Dichtungseinheit vor der Montage verhindert werden.It is also proposed that at least one of the sealing elements is made by turning. Thereby, deformations in the sealing portion of the seal unit caused by the wound-up of the seal unit before mounting can be prevented.
Weitere Vorteile ergeben sich aus der folgenden Zeichnungsbeschreibung. In den Zeichnungen ist ein Ausführungsbeispiel der Erfindung dargestellt. Die Zeichnungen, die Beschreibung und die Ansprüche enthalten zahlreiche Merkmale in Kombination. Der Fachmann wird die Merkmale zweckmäßigerweise auch einzeln betrachten und zu sinnvollen weiteren Kombinationen zusammenfassen.Further advantages emerge from the following description of the drawing. In the drawings, an embodiment of the invention is shown. The drawings, the description and the claims contain numerous features in combination. The person skilled in the art will expediently also consider the features individually and combine them into meaningful further combinations.
Die Dichtelemente
In dem vollständig montierten Zustand ist die Trennstelle
Die Maschine kann insbesondere eine Mühle zum Zementmahlen sein und insbesondere als Kugelmühle oder horizontale Mühle ausgebildet sein.The machine may in particular be a mill for cement grinding and in particular be designed as a ball mill or horizontal mill.
Bei einer Montage der Dichtungseinheit werden die Dichtelemente aneinander befestigt, wobei die Enden
Die Dichtungseinheit verhindert insbesondere das Eindringen von Schmutz in das Großlager. The sealing unit prevents in particular the ingress of dirt into the large warehouse.
Alternativ kann der Winkel 22 größer als 45° sein. Bezugszeichenliste
