Description
Die Erfindung betrifft ein Wälzlager zur Abstützung von sich gegeneinander bewegenden Maschinenteile in Form eines als Rillenkugellager oder Vierpunktlager ausgebildeten Dünnringlagers.The invention relates to a rolling bearing for supporting mutually moving machine parts in the form of a deep groove ball bearing or four-point bearing formed Dünnringlagers.
Derartige Lager sind in vielfältigen Ausführungsformen aus dem Stand der Technik bekannt, wobei die Erfindung insbesondere solche Wälzlager betrifft, die eine sehr schmale Bauweise aufweisen. In diesem Sinne bekannt sind insbesondere sogenannte Dünnringlager, wobei dort jedoch die Tragzahl durch eine kleine Kugelanzahl geringer ist als bei solchen Lagern, die die Kugeln in vorkonfektionierten Käfigen enthalten. In diesem Fall wird die Höhe des Lagers durch den Kugelkäfig definiert.Such bearings are known in various embodiments from the prior art, the invention particularly relates to such bearings, which have a very narrow construction. In this sense, in particular so-called thin-ring bearings are known, but there the load capacity is smaller by a small number of balls than in such bearings that contain the balls in prefabricated cages. In this case, the height of the bearing is defined by the ball cage.
Um ein derartiges Lager zu fixieren, kann beispielsweise ein Deckel eingesetzt werden, der jedoch den gewonnenen Platzvorteil wieder aufzehren würde. Grundsätzlich besteht auch die Möglichkeit des Aufschrumpfens, was jedoch eine zusätzliche Vorspannung auf das Lager erzeugt und somit zu einem höheren Drehmoment führt.To fix such a bearing, for example, a lid can be used, but would consume the gained space advantage again. In principle, there is also the possibility of shrinking, but this creates an additional bias on the bearing and thus leads to a higher torque.

Die
Eine vergleichbare Halterung eines Lagers durch Umformung des Randes der Lageraufnahme ist auch aus der
Der Erfindung liegt, hiervon ausgehend, die Aufgabe zugrunde, ein Befestigungsverfahren für das Lager zu finden, das es ermöglicht, die schmale Bauweise zu erhalten und dennoch eine stabile Axialsicherung für das Lager zu bieten.On this basis, the object of the invention is to find a fastening method for the bearing which makes it possible to obtain the narrow construction and nevertheless to provide a stable axial securing for the bearing.
Diese Aufgabe wird nach der Erfindung durch ein Wälzlager der eingangs genannten Art gelöst, bei welchem die Wälzkörper sich an Laufbahnen abwälzen, die an je in einem Laufringbett liegenden Laufringen ausgebildet sind, welche in Lagernuten beidseits der Lagerteilung angeordnet sind, wobei die eine Nutwand der Lagernut von einem zunächst zum Nutboden fluchtenden, axial sich erstreckenden Ringbund gebildet ist, der Teil der umschließenden, eines der Maschinenteile bildenden Konstruktion ist und nach dem Einsetzen der Laufringe sowie der Wälzkörper durch Umformung zur Anlage an die Laufringe kommt, und wobei die Seitenfläche der Laufringe eine ballige Kontur aufweist.This object is achieved according to the invention by a rolling bearing of the type mentioned, in which the rolling elements roll on raceways, which are each formed in a raceway lying raceways, which are arranged in bearing grooves on both sides of the bearing pitch, wherein a groove wall of the bearing groove is formed by a first aligned to the groove bottom, axially extending annular collar which is part of the enclosing, one of the machine parts forming construction and comes after the onset of the races and the rolling elements by deformation to rest against the races, and wherein the side surface of the races a has spherical contour.
Der durch die Erfindung erreichte Vorteil besteht im wesentlichen darin, dass durch die Umformung das Lager an seiner vorgesehenen Position axial fixiert wird, wobei der umgeformte Ringbund nicht oder allenfalls kaum zu einer Erhöhung der Bauweise führt.The advantage achieved by the invention consists essentially in the fact that the bearing is axially fixed by the deformation of the bearing at its intended position, wherein the reshaped annular collar does not or at best hardly leads to an increase in the design.
Um eine größere Tragzahl des Lagers zu erreichen, ist im Rahmen der Erfindung vorgesehen, dass die Wälzkörper in vorkonfektioniertem Käfig eingebracht werden. Um hierbei weiterhin eine geringe Bauhöhe zu gewährleisten, wird im Rahmen der Erfindung vorgeschlagen, dass der umgeformte Ringbund die Laufbahn nur maximal bis zu dem die Wälzkörper aufnehmenden Käfig überragt.In order to achieve a greater load rating of the bearing, it is provided in the context of the invention that the rolling elements are introduced in prefabricated cage. In order to continue to ensure a low overall height, it is proposed in the invention that the reshaped annular collar the career extends beyond only to the maximum of the rolling elements receiving cage.
Desweiteren hat es sich als vorteilhaft erwiesen, wenn die Breite des Ringbundes der Materialeigenschaft der umschließenden Lagerkonstruktion angepaßt ist, um hier beim Umformen optimale Ergebnisse zu erreichen.Furthermore, it has proved to be advantageous if the width of the annular collar of the material property of the enclosing bearing structure is adapted to achieve optimum results here during forming.
Die Laufringe bestehen bei dieser Ausbildung vorteilhafterweise aus einem Drahtprofil, welches für die Anwendung gerollt ist.The races are in this training advantageously made of a wire profile, which is rolled for the application.
Desweiteren ist es im Hinblick auf die Einbringung der Wälzkörper von Vorteil, wenn die Laufringe geteilt ausgebildet sind.Furthermore, it is with regard to the introduction of the rolling elements advantageous if the races are formed divided.
Ferner wird im Rahmen der Erfindung vorgeschlagen, dass die Drahtenden der Laufringe einen schräg verlaufenden Stoß aufweisen, um dadurch die Laufkultur des Lagers günstig zu beeinflußen.Furthermore, it is proposed in the context of the invention that the wire ends of the races have a slanted thrust, thereby favorably influencing the running culture of the bearing.
Um beim Umformungsvorgang, was mittels einer Bördelrolle oder einer Presse erfolgen kann, die Laufringe nicht zu beschädigen, wird im Rahmen der Erfindung vorgeschlagen, dass die Laufringe bei der Umformung des Ringbundes mittels eines Niederhalters in Position gehalten sind.In order not to damage the races in the forming process, which can be done by means of a crimping roller or a press, it is proposed in the invention that the races are held in position during the deformation of the annular collar by means of a hold-down.
Im folgenden wird die Erfindung an einem in der Zeichnung dargestellten Ausführungsbeispiel näher erläutert es zeigen:In the following the invention will be explained in more detail on an exemplary embodiment shown in the drawing, in which:
Das in der Zeichnung dargestellte Wälzlager in Form eines Rillenkugellagers oder eines Vierpunktlagers zeichnet sich durch eine sehr schmale Bauweise aus, wobei eine stabile Axialsicherung für das Lager bei diesen Bauweisen problematisch ist.The rolling bearing shown in the drawing in the form of a deep groove ball bearing or a four-point bearing is characterized by a very narrow construction, with a stable axial securing the bearing in these designs is problematic.
