Abstract
Description
Die Erfindung betrifft eine Lageranordnung, bestehend aus einem Lager und einem Lagerträger, wobei der Lagerträger zur Festlegung an einem Maschinenteil ausgebildet ist und wobei das Lager mit dem Lagerträger verbunden ist.The The invention relates to a bearing arrangement consisting of a bearing and a bearing carrier, wherein the bearing carrier is designed to be fixed to a machine part and wherein the bearing with the bearing carrier connected is.

zu verbinden. Beispiele für
derartige Konzepte sind in der
Besondere Anforderungen an die Wirtschaftlichkeit der Lageranordnung, d. h. an eine ökonomische Herstellung der Anordnung und eine einfache Montierbarkeit, treten vor allem im Großserienbereich auf, wobei insbesondere der Pkw-Bau zu nennen ist. In Pkw-Getrieben müssen in großer Stückzahl Wälzlager auf Lagerträgern festgelegt und als Einheit verbaut werden.Special Requirements for the economy of the bearing arrangement, d. H. to an economic Production of the arrangement and easy mounting, occur especially in mass production on, in particular, the car construction is mentioned. In car transmissions have to in big quantity roller bearing on storage vehicles be set and installed as a unit.
Der Erfindung liegt daher die Aufgage zugrunde, eine Lageranordnung der eingangs genannten Art derart weiterzubilden, dass eine wirtschaftliche Herstellung der Lageranordnung und eine einfache und kostengünstige Montage des Lagers am Lagerträger möglich ist.Of the The invention is therefore based on the Aufgage, a bearing assembly of the type mentioned in such a way that an economic Production of the bearing assembly and a simple and inexpensive installation of the bearing on the bearing carrier possible is.
Die Lösung dieser Aufgabe durch die Erfindung ist dadurch gekennzeichnet, dass am Lagerträger mindestens zwei Kunststoff-Formteile bleibend angeordnet sind, die sich jeweils über einen vorgegebenen Abschnitt erstrecken, und dass das Lager an einer zylindrischen Fläche mit radial nach außen oder innen gerichteter Oberflächennormale mindestens eine nutförmige Vertiefung aufweist, die zumindest teilweise in axialer Richtung des Lagers gesehen einen Hinterschnitt darstellt, wobei die mindestens zwei Kunststoff-Formteile durch in-situ-Spritzgießen mit dem Lagerträger verbunden sind, wobei die mindestens zwei Kunststoff-Formteile in die mindestens eine nutförmige Vertiefung so eingreifen, dass das Lager und der Lagerträger relativ zueinander axial und radial festgelegt sind, und wobei die nutförmige Vertiefung eine Nut ist, die zur standardmäßigen Aufnahme einer Lagerdichtung vorgesehen ist.The solution this object by the invention is characterized in that on the bearing carrier at least two plastic moldings are arranged permanently, the each over extend a predetermined section, and that the camp at a cylindrical surface with radially outward or interior surface normals at least one groove-shaped Well, which at least partially in the axial direction Seen from the bearing represents an undercut, the at least two Plastic moldings by in situ injection molding with the bearing carrier are connected, wherein the at least two plastic molded parts in the at least one groove-shaped Recess so intervene that the bearing and the bearing carrier relative axially and radially fixed to each other, and wherein the groove-shaped recess a groove is the standard intake a bearing seal is provided.
Der Lagerträger wird dabei gegebenenfalls mit Ausnehmungen zur Fixierung des Kunststoff-Formteils in ein Spritzgießwerkzeug eingelegt und das Kunststoff-Formteil dann angespritzt.Of the bearing bracket is optionally with recesses for fixing the plastic molding in an injection mold inserted and then molded the plastic molding.
Eine besondere Wirtschaftlichkeit ergibt sich dadurch, dass als nutförmige Vertiefung, in die die Kunststoff-Formteile eingreifen, eine Nut in einem Lagerring verwendet wird, die dort standardmäßig vorhanden ist und die normalerweise zur Aufnahme einer Lagerdichtung dient.A particular economy results from the fact that as a groove-shaped depression, in which the plastic moldings engage, a groove in a bearing ring which is there by default and which is normally used serves to receive a bearing seal.
Gemäß einer ersten Weiterbildung ist vorgesehen, dass mehrere, vorzugsweise mindestens drei, Kunststoff-Formteile auf einer Kreisbahn auf dem Lagerträger angeordnet sind und sich jeweils über einen Umfangsabschnitt der Kreisbahn erstrecken. Die Kunststoff-Formteile können dabei äquidistant auf der Kreisbahn angeordnet sein.According to one first training is provided that several, preferably at least three, plastic moldings on a circular path on the bearing bracket are arranged and each over a peripheral portion extend the circular path. The plastic moldings can be equidistant be arranged on the circular path.
Die Kunststoff-Formteile können weiterhin alternativ oder additiv an einer Seite des Lagerträgers oder an der radial innenliegenden Seite einer Bohrung oder Aussparung im Lagerträger angeordnet sein.The Plastic moldings can furthermore alternatively or additionally on one side of the bearing carrier or on the radially inner side of a hole or recess in the bearing carrier be arranged.
Der Lagerträger hat mit Vorteil eine im wesentlichen ebene Kontur.Of the bearing bracket has a substantially flat contour with advantage.
Gemäß einer Weiterbildung ist vorgesehen, dass die mindestens eine nutförmige Vertiefung im Außenring des Lagers angeordnet ist.According to one Further development is provided that the at least one groove-shaped depression in the outer ring of the warehouse is arranged.
Eine weitere montagetechnisch günstige Ausgestaltung sieht vor, dass das Kunststoff-Formteil einen als Schnappnase ausgebildeten Abschnitt aufweist, der in die nutförmige Vertiefung eingreift.A further assembly-technically favorable configuration provides that the plastic molding designed as a snap nose Section has, which engages in the groove-shaped recess.
Die vorgeschlagene Lageranordnung zeichnet sich dadurch aus, dass sie sehr leicht und damit preiswert herzustellen und zu montieren ist.The proposed bearing arrangement is characterized in that they very easy and thus inexpensive to manufacture and assemble.
Insbesondere kann in einem verketteten Prozess vorgesehen werden, dass zunächst die Kunststoff-Formteile am Lagerträger angespritzt und anschließend – nach Aushärtung des Kunststoffmaterials – die Verbindung mit dem Lager vorgenommen wird.Especially can be provided in a concatenated process that first the Plastic molded parts on the bearing carrier molded and then - after curing of the Plastic material - the Connection with the warehouse is made.
