Abstract
Zylinderrollenlagerkäfig mit wenigstens einem ringartigen Seitenelement, von dessen wenigstens einer Stirnseite zum Bilden von Aufnahmen für zueinander mit parallelen Hauptachsen angeordneten Rollen Stegelemente abzweigen, wobei in wenigstens einem radial äußeren und/oder inneren Oberflächenbereich der Stegelemente, der an einer Führungsfläche für den Käfig zum Geführtwerden vorgesehen ist, wenigstens in einem Bereich hin zum Seitenelement derart gestaltet ist, dass bei Betrachtung des Stegelementquerschnitts die den Rollenmänteln zugewandten Seitenflächen des Stegelements scharfkantig in geradlinige, von den Seitenflächen hin zur Stegmitte mit an Höhe zunehmende Bereiche übergehen, und die geradlinigen Bereiche in Stegmitte in eine Verrundung übergehen.Cylindrical roller bearing cage having at least one annular side member, branch off at least one end face for forming receptacles arranged parallel to each other for main axes web members, wherein in at least one radially outer and / or inner surface region of the web elements provided on a guide surface for the cage to be guided is at least in an area towards the side member designed such that when viewing the web element cross section, the roller coats facing side surfaces of the bar edge sharp edge into rectilinear, from the side surfaces to the web center with increasing height areas, and the rectilinear areas in web center in one Go rounding.
Description
Die Erfindung betrifft einen Zylinderrollenlagerkäfig und eine Rollenlagerung, wie sie insbesondere zum drehbaren Lagern einer Kurbelwelle und einer Pleuelstange an der Kurbelwelle eingesetzt werden. The invention relates to a cylindrical roller bearing cage and a roller bearing, as used in particular for rotatably supporting a crankshaft and a connecting rod to the crankshaft.
Insbesondere bei der Verwendung an Kurbelwellen sollen Rollenlagerungen und auch deren Rollenlagerkäfige dahingehend Vorteile aufweisen, dass sie leichtgewichtig sind, eine hohe Belastungskapazität, eine hohe Festigkeit und eine hohe Leistungsfähigkeit bei hohen Umdrehungen aufweisen und darüber hinaus in der Lage sind, unter anspruchsvollen Schmierungsbedingungen verwendet werden zu können.Especially when used on crankshafts, roller bearings and also their roller bearing cages are said to have advantages in that they are lightweight, have high load capacity, high strength and high speed performance, and are capable of being used under demanding lubrication conditions can.

Eine Aufgabe der vorliegenden Erfindung ist es daher, eine Verbesserung bei einem Zylinderrollenlagerkäfig und einer Rollenlagerung, insbesondere bei Verwendung an einer Kurbelwelle zu schaffen. An object of the present invention is therefore to provide an improvement in a cylindrical roller bearing cage and a roller bearing, in particular when used on a crankshaft.
Die Aufgabe wird durch die Gegenstände der Ansprüche 1, 9 und 11 gelöst. Vorteilhafte Ausgestaltungen sind in den Unteransprüchen beschrieben. The object is solved by the subject-matter of claims 1, 9 and 11. Advantageous embodiments are described in the subclaims.
Anspruch 1 betrifft einen Zylinderrollenlagerkäfig mit wenigstens einem ringartigen Seitenelement, von dessen wenigstens einer Stirnseite zum Bilden von Aufnahmen für zueinander mit parallelen Hauptachsen angeordneten Rollen Stegelemente abzweigen, wobei in wenigstens einem radial äußeren und/oder inneren Oberflächenbereich der Stegelemente, der an einer Führungsfläche für den Käfig zum Geführtwerden vorgesehen ist, wenigstens in einem Bereich hin zum Seitenelement derart gestaltet ist, dass bei Betrachtung des Stegelementquerschnitts die den Rollenmänteln zugewandten Seitenflächen des Stegelements scharfkantig in geradlinige, von den Seitenflächen hin zur Stegmitte mit an Höhe zunehmende Bereiche übergehen, und die geradlinigen Bereiche in Stegmitte in eine Verrundung übergehen.Claim 1 relates to a cylindrical roller bearing cage with at least one annular side member, branch off at least one end face for forming receptacles for parallel to each other with parallel main axes web elements, wherein in at least one radially outer and / or inner surface region of the web elements, on a guide surface for the Cage is provided to be guided, at least in an area towards the side member is designed such that when viewing the web element cross section, the roller coats facing side surfaces of the web element sharp edged in rectilinear, from the side surfaces toward the web center with increasing height areas, and the rectilinear areas At the middle of the bridge, make a rounding.
Durch die besagte Ausbildung wird mit besonderem Vorteil ein Aufschwimmen des Käfigs erleichtert, so dass sich ähnlich wie bei einem Gleitlager gute Gleiteigenschaften des Käfigs gegenüber seiner Lagerumgebung ergeben.By said training a floating of the cage is facilitated with particular advantage, so that similar to a slide bearing good sliding properties of the cage compared to its storage environment arise.
Anspruch 11 betrifft eine Rollenlagerung mit einem Rollenlagerkäfig, wobei der Käfig in Längsrichtung in zwei gleichartige Käfighälften geteilt ausgebildet ist, und wobei die Rollenlagerung derart ausgestaltet ist, dass der Käfig frei von einer Rollenführung ist und die Käfighälfte an entsprechenden Führungsflächen für den Käfig gleichzeitig radial innen und außen geführt ist.Claim 11 relates to a roller bearing with a roller bearing cage, wherein the cage is formed longitudinally divided into two similar cage halves, and wherein the roller bearing is configured such that the cage is free of a roller guide and the cage half at corresponding guide surfaces for the cage simultaneously radially inside and led outside.
Durch diese sozusagen gemischte gleichzeitige Innen- und Außenführung des Käfigs wird mit besonderem Vorteil erreicht, dass beispielsweise bei Einsatz an einer Kurbelwelle bei Betrieb durch die charakteristische Bewegung besagter Lagerstelle ungünstige Krafteinwirkungen auf den Käfig verhindert werden.Through this so-called mixed simultaneous inner and outer guide of the cage is achieved with particular advantage that, for example, when used on a crankshaft during operation by the characteristic movement of said bearing unfavorable forces on the cage can be prevented.
Weitere Vorteile, Merkmale und Einzelheiten der Erfindung ergeben sich aus dem im Folgenden beschriebenen Ausführungsbeispiel der Erfindung anhand der Figuren. Dabei zeigen:Further advantages, features and details of the invention will become apparent from the embodiment of the invention described below with reference to FIGS. Showing:

In anderen Ausführungsformen kann der Käfig natürlich auch aus anderen Materialien, beispielsweise Kunststoff, Stahl, Titan oder auch Materialverbünden ausgebildet sein. Das vorausgehend Beschriebene kann in anderen Ausführungsformen natürlich auch bei entsprechenden Lagerungen bei Nockenwellen oder Ausgleichswellen verwendet werden.Of course, in other embodiments, the cage may also be formed of other materials, such as plastic, steel, titanium or composite materials. Of course, in other embodiments, what has been described above can also be used for corresponding bearings in camshafts or balancing shafts.
