Abstract
Die Erfindung geht aus von einer Baueinheit mit einem Bauelement (10), welches wenigstens eine erste Laufbahn (12) zum Abrollen von Wälzkörpern (14) aufweist, wenigstens einem ersten Dichtungselement (16) und zumindest einem Dichtungsbefestigungselement (18), welches das erste Dichtungselement an dem Bauelement befestigt. Es wird vorgeschlagen, dass das Dichtungsbefestigungselement wenigstens eine Bordfläche (20) aufweist, welche dazu vorgesehen ist, dass an ihr bei Relativbewegungen zwischen den Wälzkörpern und der ersten Laufbahn die Wälzkörper anlaufen.The invention is based on a structural unit with a component (10) which has at least one first raceway (12) for rolling rolling elements (14), at least one first sealing element (16) and at least one sealing fastening element (18) which forms the first sealing element attached to the device. It is proposed that the sealing fastening element has at least one flange surface (20), which is provided so that the rolling elements start on it during relative movements between the rolling elements and the first raceway.
Description
Die Erfindung geht aus von einer Baueinheit nach dem Oberbegriff des Anspruchs 1. The invention is based on a structural unit according to the preamble of claim 1.
Es sind Kreuzgelenkbüchsen bzw. -lager für Gelenkwellen bekannt. Diese haben einen Wälzkörpersatz basierend auf ein- oder mehrreihigen Nadelrollen. An der geschlossenen Seite der Büchse werden diese meist durch eine Anlaufscheibe oder einen in den Büchsenboden integrierten metallischen Bord geführt. An der offenen Seite der Büchse grenzen die Wälzkörper an eine Dichtung, die Fettverlust sowie das Eindringen von Schmutz verhindern soll. Da die Dichtung in der Regel aus Gummi oder ähnlichen Materialien hergestellt sind, bieten diese den Wälzkörpern nur einen unzureichenden Gleitkontakt. Um dies zu verbessern, werden zur Trennung der Bauteile und zur Realisierung eines entsprechenden Gleitkontaktes zu den Wälzkörpern Metall- oder Kunststoffscheiben bzw. Federn eingesetzt. There are known Kreuzgelenkbüchsen or bearing for propeller shafts. These have a rolling element set based on single or multi-row needle rollers. On the closed side of the bush, these are usually guided by a thrust washer or a metallic board integrated into the bush bottom. On the open side of the bush, the rolling elements are adjacent to a seal intended to prevent the loss of grease and the ingress of dirt. Since the seal are usually made of rubber or similar materials, they offer the rolling elements only inadequate sliding contact. To improve this, metal or plastic disks or springs are used to separate the components and to realize a corresponding sliding contact with the rolling elements.
Die Aufgabe der Erfindung besteht insbesondere darin, eine gattungsgemäße Baueinheit mit einer hohen Effizienz bereitzustellen. 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 assembly with a high efficiency. 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 Baueinheit mit einem Bauelement, welches wenigstens eine erste Laufbahn zum Abrollen von Wälzkörpern aufweist, wenigstens einem ersten Dichtungselement und zumindest einem Dichtungsbefestigungselement, welches das erste Dichtungselement an dem Bauelement befestigt. The invention is based on a structural unit with a component which has at least one first raceway for rolling rolling elements, at least one first sealing element and at least one sealing fastening element which fixes the first sealing element to the structural element.
Es wird vorgeschlagen, dass das Dichtungsbefestigungselement wenigstens eine Bordfläche aufweist, welche dazu vorgesehen ist, dass an ihr bei Relativbewegungen zwischen den Wälzkörpern und der ersten Laufbahn die Wälzkörper anlaufen. Unter einem „Dichtungsbefestigungselement“ soll insbesondere ein Befestigungselement verstanden werden, welches zur Befestigung einer Dichtung geeignet ist. Unter „vorgesehen“ soll insbesondere speziell ausgestattet und/oder speziell ausgelegt verstanden werden. Dadurch kann eine hohe Effizienz erreicht werden. Insbesondere kann eine kostengünstige Bauweise, eine geringe Anzahl von Bauteilen und ein geringes Gewicht erreicht werden. It is proposed that the seal fastening element has at least one flange, which is provided so that the rolling elements start on it during relative movements between the rolling elements and the first raceway. A "sealing fastening element" is to be understood in particular a fastening element which is suitable for fastening a seal. By "intended" is intended to be understood in particular specially equipped and / or specially designed. As a result, high efficiency can be achieved. In particular, a cost-effective design, a small number of components and a low weight can be achieved.
Vorzugsweise ist die erste Laufbahn eine äußere Laufbahn eines Radiallagers. Preferably, the first raceway is an outer race of a radial bearing.
Ferner wird vorgeschlagen, dass das erste Dichtungselement einen Radialwellendichtring aufweist. It is also proposed that the first sealing element has a radial shaft sealing ring.
Mit Vorteil ist das Dichtungsbefestigungselement zumindest formschlüssig und/oder zumindest kraftschlüssig an dem Bauelement befestigt und/oder aus Metall. Advantageously, the seal fastening element is at least positively and / or at least non-positively attached to the component and / or metal.
Vorzugsweise weist die Baueinheit wenigstens ein zweites Dichtungselement auf, welches an dem ersten Dichtungselement anliegt. Preferably, the structural unit has at least one second sealing element, which bears against the first sealing element.
Ferner wird ein Wälzlager mit der Baueinheit vorgeschlagen. Vorzugsweise ist das Wälzlager ein ein- oder mehrreihiges Nadellager. Furthermore, a roller bearing is proposed with the unit. Preferably, the rolling bearing is a single or multi-row needle bearing.
Außerdem wird ein Kreuzgelenk mit dem Wälzlager vorgeschlagen. Insbesondere kann das Bauelement wenigstens teilweise in einem Lagerträger des Kreuzgelenks angeordnet sein und der Lagerträger an einer Gelenkgabel des Kreuzgelenks befestigt sein. In addition, a universal joint with the rolling bearing is proposed. In particular, the component may be at least partially disposed in a bearing bracket of the universal joint and the bearing bracket to be attached to a yoke of the universal joint.
Vorzugsweise weist ein Kreuzstück des Kreuzgelenks wenigstens einen Achsstummel mit einer zweiten Laufbahn auf, welche eine Innenlaufbahn des Wälzlagers ist. Preferably, a crosspiece of the universal joint has at least one stub axle with a second raceway, which is an inner raceway of the rolling bearing.
Weitere Vorteile ergeben sich aus der folgenden Zeichnungsbeschreibung. In der Zeichnung 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 drawing, 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.
