Abstract
Description
Die Erfindung geht aus von einer Lagerträgereinheit nach dem Oberbegriff des Anspruchs 1. The invention is based on a bearing carrier unit according to the preamble of claim 1.
Es ist eine Lagerträgereinheit bekannt, welche ein Lager und ein Lagerträgerelement aufweist. Das Lagerträgerelement ist dünnwandig und aus Blech gebildet. Ferner ist an dem Lagerträgerelement ein Außenring des Lagers befestigt. It is known a bearing support unit, which has a bearing and a bearing support member. The bearing carrier element is thin-walled and formed from sheet metal. Further, an outer ring of the bearing is attached to the bearing support member.
Die Aufgabe der Erfindung besteht insbesondere darin, eine gattungsgemäße, effiziente Lagerträgereinheit 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, efficient bearing support unit. 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 Lagerträgereinheit mit zumindest einem Lager, wenigstens einem Lagerträgerelement, welches zumindest teilweise dünnwandig ist und das zumindest teilweise aus Kunststoff und/oder zumindest teilweise aus Blech gebildet ist, wobei an dem Lagerträgerelement wenigstens ein Außenring des Lagers befestigt ist. The invention relates to a bearing support unit with at least one bearing, at least one bearing support element which is at least partially thin-walled and which is at least partially made of plastic and / or at least partially made of sheet metal, wherein at least one outer ring of the bearing is attached to the bearing support member.
Es wird vorgeschlagen, dass die Lagerträgereinheit wenigstens eine Dichtungseinheit mit zumindest einer Befestigungsfläche aufweist, mittels der die Dichtungseinheit mittelbar und/oder unmittelbar an dem Lagerträgerelement befestigt ist und die eine Achse umgibt, um welche ein Innenring des Lagers relativ zu dem Außenring drehbar ist. Darunter, dass das Lagerträgerelement „zumindest teilweise dünnwandig“ ist, soll insbesondere verstanden werden, dass das Lagerträgerelement wenigstens einen Wandbereich aufweist, welcher eine Wandstärke von weniger als 1 cm, vorzugsweise weniger als 6 mm und besonders bevorzugt weniger als 4 mm aufweist. Unter einem "Kunststoff" soll insbesondere ein organisches Polymer und vorzugsweise ein Festkörper verstanden werden, dessen Grundbestandteil synthetisch oder halbsynthetisch aus monomeren organischen Molekülen hergestellt ist. Unter "Blech" soll insbesondere ein Metallelement verstanden werden, welches bei seiner Herstellung umgeformt und vorzugsweise gewalzt wurde. Mit einer erfindungsgemäßen Ausgestaltung kann eine Lagerträgereinheit mit einer hohen Effizienz bereitgestellt werden. Insbesondere kann eine kompakte, kostengünstige und leicht zu montierenden Anordnung erreicht werden, und zwar insbesondere in dem Fall, in welchem die Lagerträgereinheit in eine Vorrichtung eingebaut ist. Insbesondere wird in diesem Fall durch die Lagerträgereinheit eine kompakte, kostengünstige und stabile Anordnung und eine einfache Montage im Vergleich zu einer Anordnung erzielt, bei welcher das Lagerträgerelement kein Kunststoff oder Blech aufweist oder die Dichtungseinheit an einem Gehäuse befestigt ist.It is proposed that the bearing support unit has at least one sealing unit with at least one fastening surface, by means of which the sealing unit is indirectly and / or directly attached to the bearing support member and which surrounds an axis about which an inner ring of the bearing is rotatable relative to the outer ring. By the fact that the bearing support element is "at least partially thin-walled" should be understood in particular that the bearing support member has at least one wall portion having a wall thickness of less than 1 cm, preferably less than 6 mm and more preferably less than 4 mm. A "plastic" is to be understood in particular as meaning an organic polymer and preferably a solid whose basic constituent is produced synthetically or semi-synthetically from monomeric organic molecules. By "sheet metal" is meant in particular a metal element which has been formed during its production and preferably rolled. With an embodiment according to the invention, a bearing support unit can be provided with a high efficiency. In particular, a compact, inexpensive and easy to install arrangement can be achieved, in particular in the case in which the bearing support unit is installed in a device. In particular, in this case, a compact, inexpensive and stable arrangement and a simple assembly compared to an arrangement is achieved by the bearing support unit, wherein the bearing support member has no plastic or sheet metal or the seal unit is attached to a housing.
Vorzugsweise ist das gesamte Lagerträgerelement dünnwandig ausgebildet. Darunter, dass das „gesamte Lagerträgerelement dünnwandig ausgebildet ist“, soll insbesondere verstanden werden, dass ein gesamter Wandbereich des Lagerträgerelements – bis auf Wandbereiche mit Verstärkungsstrukturen – eine Wandstärke von weniger als 1 cm, vorzugsweise weniger als 6 mm und besonders bevorzugt weniger als 4 mm aufweist, wobei die Verstärkungsstrukturen insbesondere durch Rippen gebildet sein können. Dadurch kann eine kompakte, kostengünstige und stabile Bauweise erreicht werden.Preferably, the entire bearing support member is formed thin-walled. By the fact that the "entire bearing support element is thin-walled", should be understood in particular that a whole wall area of the bearing support element - except for wall areas with reinforcing structures - a wall thickness of less than 1 cm, preferably less than 6 mm and more preferably less than 4 mm , wherein the reinforcing structures may be formed in particular by ribs. As a result, a compact, inexpensive and stable construction can be achieved.
Ferner wird vorgeschlagen, dass die Dichtungseinheit mittels höchstens zwei einstückig ausgebildeten Verbindungselementen an dem Lagerträgerelement befestigt ist. Unter "einstückig“ soll insbesondere aus einer Spritzung und/oder aus einem Guss und/oder nur unter Zerstörung trennbar verstanden werden. Hierdurch kann eine konstruktiv einfache und kostengünstige Bauweise erreicht werden.Furthermore, it is proposed that the sealing unit is fastened to the bearing carrier element by means of at most two integrally formed connecting elements. The term "integral" should be understood to mean that it can be separated, in particular, from a spray and / or cast and / or only with destruction, thereby enabling a structurally simple and cost-effective design to be achieved.

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, embodiments of the invention are 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 Lagerträgereinheit weist ein Sensorelement
Die Lagerträgereinheit weist einen Befestigungsbereich
Das Sensorelement
Die Dichtungseinheit ist einstückig aus einem Elastomer gebildet. Es besteht kein unmittelbarer materieller Kontakt zwischen der Dichtungseinheit und dem Lager, so dass keine Reibung zwischen dem Lager und der Dichtungseinheit auftreten kann. Außerdem weist die Dichtungseinheit eine Dichtlippe
Bei einem Verfahren zur Herstellung der Lagerträgereinheit wird die Befestigungsfläche stoffschlüssig an dem Lagerträgerelement befestigt. Ferner wird der Außenring an dem Lagerträgerelement befestigt.In a method for producing the bearing carrier unit, the fastening surface is firmly bonded to the bearing carrier element. Further, the outer ring is fixed to the bearing support member.
In einem vollständig montierten und eingebauten Zustand ist die Lagerträgereinheit in eine Vorrichtung mit einem Elektromotor, wie zum Beispiel einer Kraftfahrzeugvorrichtung, eingebaut. Dabei dichtet die Dichtungseinheit einen Ölraum
Des weiteren weist das Lagerträgerelement an einem Bereich, welcher in Radialrichtung
