Eine Aufgabe der vorliegenden Erfindung ist es, einen verbesserten Wälzlagerkäfig zu schaffen, der insbesondere einfach und damit kostengünstig herstellbar ist.A Object of the present invention is an improved rolling bearing cage to create the particular simple and therefore inexpensive to produce is.
Die Aufgabe wird durch den Gegenstand des Anspruchs 1 gelöst. Vorteilhafte Ausgestaltungen sind in den Unteransprüchen beschrieben.The The object is solved by the subject matter of claim 1. Advantageous embodiments are in the subclaims described.
Gemäß Anspruch 1 beinhaltet ein Wälzlagerkäfig folgende Merkmale:
- – Der Käfig umfasst ein ringartiges Umfangselement von dem Stegelemente abzweigen, zwischen denen Wälzkörper des Wälzlagers anordenbar sind,
- – das Umfangselement umfasst zwei ringartige Halteelemente,
- – jedes der Stegelemente steht mit beiden Haltelementen in Kontakt, und
- – das Umfangselement weist zwei zu den Halteelementen korrespondierende ringartige Fixierelemente auf, mittels der die Stegelemente an den Halteelementen fixiert sind.
- - The cage comprises a ring-like peripheral element of the web elements branch off, between which rolling elements of the rolling bearing can be arranged,
- The peripheral element comprises two ring-like holding elements,
- - Each of the web elements is in contact with both holding elements, and
- - The peripheral element has two corresponding to the holding elements ring-like fixing elements, by means of which the web elements are fixed to the holding elements.
Ein Käfig des beanspruchten Aufbaus ist besonders einfach und kostengünstig herstellbar. Durch die Verwendung der ringartigen Halteelemente lassen sich die Stegelemente einfach in Kontakt bringen und daraufhin mit den ringartig ausgebildeten Fixierelementen an den Halteelementen fixieren, so dass ein stabiler Wälzlagerkäfig entsteht. Im Vergleich zu bekannten Herstellungsmethoden für Wälzlagerkäfige, bei denen beispielsweise ein Käfig aus einem hohlzylinderartigen Rohling herausgearbeitet wird, bietet der Wälzlagerkäfig gemäß der Erfindung den Vorteil, dass praktisch kein Materialabfall durch das Herausarbeiten insbesondere der Käfigtaschen entsteht. Insofern ergibt sich somit insbesondere ein Vorteil durch eine Materialeinsparung.One Cage of the claimed construction is particularly simple and easy inexpensive to produce. By using the ring-like Retaining elements can easily bring the web elements in contact and then with the ring-shaped fixing to the Fix holding elements, so that a stable rolling bearing cage arises. Compared to known manufacturing methods for Rolling bearing cages, where, for example, a Cage made out of a hollow cylinder-like blank is provided by the rolling bearing cage according to the Invention the advantage that virtually no waste material through the working out in particular of the cage pockets arises. In this respect, this results in particular an advantage through a material saving.
In einer vorteilhaften Ausführungsform der Erfindung ist jedes der Fixierelemente einstückig ausgebildet. Dies bietet insbesondere den Vorteil einer aufwandsarmen Montage des mehrstückigen Wälzlagerkäfigs. So ist es nicht erforderlich, in diesem Fall jede Verbindungsstelle zwischen den Stegelementen und den Halteelementen einzeln mittels Fixierelementen zu fixieren. Das Einlegen zweier Fixierelemente, die jeweils einstückig ausgebildet sind, kann in zwei separaten, oder in einem Arbeitsgang erfolgen.In An advantageous embodiment of the invention is each the fixing formed integrally. This offers in particular, the advantage of a low-effort assembly of multi-piece roller bearing cage. So it is not necessary in this case any connection point between the web elements and the holding elements individually by means of fixing elements to fix. The insertion of two fixing elements, each in one piece are formed, can be done in two separate, or in one operation.
In einer weiteren vorteilhaften Ausführungsform der Erfindung weisen die Stegelemente jeweils zwei Nuten auf, in die jeweils eines der Halteelemente eingreift. So lässt sich bereits vor Montage der Fixierelemente ein vergleichsweise stabiler Wälzlagerkäfig aufbauen, bei dem die Stegelemente bereits in ihrer endgültigen Position sicher an den Halteelementen befestigt sind. Im unbelasteten Zustand ist der Wälzlagerkäfig somit bereits einigermaßen stabil. Die Fixierelemente dienen letztlich noch dazu, den Wälzlagerkäfig auch für beanspruchte Situationen, also im montierten Wälzlager mit Wälzkörpern zu stabilisieren.In a further advantageous embodiment of the invention The web elements each have two grooves, in each of which one the holding elements engages. This is already possible Assembly of the fixing a comparatively stable roller bearing cage build in which the web elements already in their final Position are securely attached to the holding elements. In the unloaded Condition is the rolling bearing cage thus already reasonably stable. The fixing ultimately serve to the rolling bearing cage also for stressed situations, ie in the assembled rolling bearing to stabilize with rolling elements.
Vorteilhaft ist eine Ausgestaltung der Erfindung derart, dass die Nuten in radialer Richtung außen an den Stegelementen ausgebildet sind und die Halteelemente derart angeordnet sind, dass sie bezüglich der radialen Richtung von außen in die Nuten der Stegelemente eingreifen. In dieser Anordnung wird eine besonders einfache Methode der Fixierung der Stegelemente an den Halteelementen mittels der Fixierelemente erreicht. Aufgrund der relativen Anordnung der Stegelemente und der Halteelemente können erstere nur bezüglich der radialen Richtung nach innen von den Halteelementen gelöst werden. In dieser Richtung werden sie allerdings durch die innenseitig angeordneten Fixierelemente in ihrer Position gehalten. Folglich korrespondieren in radialer Richtung die Fixierelemente und die Halteelemente von innen nach außen miteinander, wobei die Stegelemente zwischen den Fixierelementen und den Halteelementen liegen.Advantageous is an embodiment of the invention such that the grooves in radial Outwardly formed on the web elements and the holding elements are arranged so that they respect the radial direction from the outside into the grooves of the web elements intervention. In this arrangement becomes a particularly simple method the fixation of the web elements to the holding elements by means of the fixing elements reached. Due to the relative arrangement of the web elements and the holding elements can the former only with respect the radial direction inwardly of the holding elements dissolved become. In this direction, however, they are by the inside arranged fixing elements held in position. consequently correspond in the radial direction, the fixing elements and the Holding elements from inside to outside with each other, wherein the Web elements between the fixing elements and the holding elements lie.
In einer vorteilhaften Ausgestaltung der Erfindung weisen die Fixierelemente jeweils eine teilweise umlaufende Nut auf, in die das jeweilige Halteelement eingreift, wobei die Fixierelemente im Bereich der Stegelemente taschenartige Ausformungen zur Aufnahme der Stegelemente aufweisen. In dieser besonders einfach ausgebildeten Ausführungsform der Erfindung sind die Fi xierelemente auch außerhalb der Stegelemente durch die umlaufende Nut mit den Halteelementen verbunden, was eine besonders stabile Anordnung zur Folge hat. Die Stegelemente kommen in taschenartigen Ausformungen der Fixierelemente zu liegen, so dass sie sicher an ihrer vordefinierten Position gehalten werden. In Umlaufrichtung des Wälzlagerkäfigs liegen die Nuten der Stegelemente und des jeweils korrespondierenden Fixierelements beidseitig in der Flucht, so dass eine hohe Stabilität gewährleistet ist.In an advantageous embodiment of the invention, the fixing elements in each case a partially circumferential groove into which the respective Holding element engages, wherein the fixing elements in the field of Web elements pocket-like formations for receiving the web elements exhibit. In this particularly simple embodiment of the Invention are the fi xierelemente also outside the web elements connected by the circumferential groove with the holding elements, which is a particularly stable arrangement result. The web elements come lie in pocket-like formations of the fixing, so that they are held securely in their predefined position. In the direction of rotation of the rolling bearing cage are the Grooves of the web elements and the respective corresponding fixing element both sides in flight, allowing a high stability is guaranteed.

Die beschriebenen Ausführungsbeispiele haben jeweils mögliche Ausgestaltungen der Erfindung gezeigt. Dabei lagen die Fixierelemente jeweils bezüglich der radialen Richtung außerhalb des durch die Mittelpunkte der Wälzkörper gebildeten Rollenkreises. In alternativen Ausführungsformen der Erfindung ist es ebenfalls möglich, den Aufbau der beanspruchten Wälzlagerkäfige in radialer Richtung umgekehrt zu gestalten. In diesem Fall waren die Halteelemente und die Fixierelemente in radialer umgekehrter Anordnung bezüglich der Stegelemente angeordnet. Somit lägen in diesen Fällen die Fixierelemente jeweils innerhalb des Rollenkreises, wie es bei am Innenring des Wälzlagers geführten Käfigen bekannt ist.The described embodiments have each possible Embodiments of the invention shown. There were the fixing elements each with respect to the radial direction outside of the formed by the centers of the rolling elements Role circle. In alternative embodiments of the invention It is also possible to build the claimed Rolling bearing cages reversed in the radial direction to design. In this case, the retaining elements and the fixing elements in radial reverse arrangement with respect to the web elements arranged. Thus, in these cases would be the fixing each within the roller circle, as it is at the inner ring of Rolling bearing guided cages known is.
