Abstract
Description
Die Erfindung betrifft ein Wälzlager in Form eines Rillenkugellagers oder eines Vierpunktlagers, bei dem die Wälzkörper sich an Laufbahnen abwälzen, die an je in einem Laufringbett liegenden Laufringen ausgebildet sind, welche in Lagernuten beidseits der Lagerteilung angeordnet sind.The The invention relates to a rolling bearing in the form of a deep groove ball bearing or a four-point bearing, at the rolling elements themselves to roll on careers, formed on each lying in a race bed races are, which are arranged in Lagernuten on both sides of the bearing pitch are.
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 in manifold embodiments known from the prior art, wherein the invention in particular concerns such bearings, which have a very narrow construction. Known in this sense are in particular so-called thin-ring bearings, where, however, the load rating by a small number of balls less is as in such bearings, which the balls in prefabricated cages contain. 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.Around To fix such a bearing, for example, a lid be used, but the gained space advantage again would consume. in principle there is also the possibility of Shrinking, but what an additional bias on the Generates bearing and thus leads to a higher torque.
Der Erfindung liegt daher 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.Of the Invention is therefore the object of a fastening method for the Find bearings that make it possible to maintain the slim design and yet a stable axial lock for the To offer bearings.
Diese Aufgabe wird nach der Erfindung dadurch gelöst, dass die eine Nutwand der Lagernut von einem zunächst zum Nutzboden fluchtenden, axial sich erstreckenden Ringbund gebildet ist, der nach dem Einsetzen der Laufringe sowie der Wälzkörper durch Umformung zur Anlage an die Laufringe kommt.These The object is achieved according to the invention in that the one groove wall of the Lagernut of a first aligned to the useful floor, axially extending annular collar formed is, after inserting the races and the rolling elements by Forming comes to rest on the races.
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.Of the The advantage achieved by the invention consists essentially in that by the deformation of the bearing at its intended position axially is fixed, with the reshaped collar not or at best hardly to an increase the construction leads.
Vorteilhaft im Rahmen der Erfindung ist es dabei, wenn der Ringbund von einem diesengegenüber radial auswärts eingebrachten Einstich in der umschließenden Konstruktion des Lagers gebildet ist.Advantageous in the context of the invention, it is when the annular collar of a this against radially outward introduced puncture in the enclosing construction of the bearing is formed.
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 ungeformte Ringbund die Laufbahn nur maximal bis zu dem die Wälzkörper aufnehmenden Käfig überragt.Around a larger load rating reach the camp, is provided in the invention that the rolling elements in pre-assembled cage be introduced. In order to continue to ensure a low height, is proposed in the invention that the unshaped Ring collar the track only a maximum of up to the rolling elements receiving Cage surmounted.
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 the material property of the enclosing bearing construction is adapted to achieve optimum results here during forming.
Die Laufringe bestehen bei dieser Ausbildung vorteilhafterweise aus geeignetem geschliffenem oder gezogenem Drahtprofil, welches für die Anwendung gerollt ist.The Running rings are advantageously made in this training suitable ground or drawn wire profile, which is suitable for the application rolled.
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 Running rings 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.Further is proposed in the invention that the wire ends of the races an oblique have a continuous impact, thereby to favorably affect the running culture of the warehouse.
Um beim Umvorgang, 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.Around when Umvorgang, which means a crimping roller or a press can be done not to damage the races, is within the scope of the invention suggested that the races in the transformation of the annular collar held in place by means of a hold-down.
Schließlich hat es sich im Rahmen der Erfindung als vorteilhaft erwiesen, wenn die Seitenfläche der Laufringe eine ballige oder dazu vergleichbare Kontur aufweist. Dies stellt sicher, dass das Material der umschließenden Konstruktion beim Umformen bzw. beim Umbördeln nicht über Gebühr beansprucht wird und im übrigen einen guten Formschluß gewährleistet.Finally has It has proved to be advantageous in the context of the invention, when the Side surface of the Running rings has a spherical or comparable contour. This ensures that the material of the enclosing construction during forming or when flanging no over fee is claimed and the rest ensures a good fit.
Im folgenden wird die Erfindung an einem in der Zeichnung dargestellten Ausführungsbeispiel näher erläutert es zeigen:in the Next, the invention will be illustrated on a drawing embodiment it explains in more detail demonstrate:
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 in the drawing illustrated rolling bearings in Shape of a deep groove ball bearing or a four-point bearing characterized by a very narrow construction, with a stable axial lock for the Warehouse in these designs is problematic.
