Description
Axialwälzlager Die Erfindung bezieht sich auf ein Axialwälzlagermit in einem Käfig gefiffirtenWälzkörpern.Axial roller bearing The invention relates to an axial roller bearing with rolling elements locked in a cage.
Häufig kommt es vor, daß bei der Montage von Axialwälzlagern so große Kräfte auf die Wälzkörper des Wälzlagers ausgeübt werden, daß eine bleibende Verformung, die sogenannte Brinellierung, hervorgerufen wird. Diese Gefahr besteht insbesondere dann, wenn das Geräteteil, in dem das Axialwälzlager eingebaut wurde, anschließend vernietet wird. Die Gefahr einer Brinellierung besteht natürlich auch dann, wenn während des Betriebes mit plötzlichen außergewöhnlichen Stoßbeanspruchungen gerechnet werden muß.It often happens that when assembling axial roller bearings such large Forces are exerted on the rolling elements of the rolling bearing that a permanent deformation, the so-called brinelling, is caused. This is a particular danger then, if the device part in which the axial roller bearing was installed, then is riveted. Of course, there is also a risk of brinelling if Sudden, extraordinary shock loads are expected during operation must become.
Aufgabe der Erfindung ist es, ein Axialwälzlager in der Weise auszubilden, daß die Gefahr einer Brinellierung beim Auftreten von Stoßbelastungen, sei es während der Montage oder während des Betriebes, nicht besteht.The object of the invention is to design a thrust roller bearing in such a way that that the risk of brinelling when impact loads occur, be it during the assembly or during operation, does not exist.
Diese Aufgabe wird bei einem Axialwälzlager der eingangs genannten Art dadurch gelöst, daß im Käfig zur Vermeidung einer plastischen Verformung der Wälzlager-Laufflächen infolge axialer Laststöße zusätzlich mehrere Gleitkörper angeordnet sind, deren Abmessung in axialer Richtung etwas geringer ist als der Durchmesser der'Wälzkörper, so daß sie mit ihrer im Vergleich zu den Wälzkörpern großen Fläche nur beim Auftreten axialer Laststöße und wegen der elastischen Verformbarkeit der Wälzlager-Laufflächen an den Wälzlager-Laufflächen anliegen, ehe deren elastische Verformung in eine plastische Verformung übergehen kann.In the case of an axial roller bearing, this task becomes the one mentioned at the beginning Kind of solved in that in the cage to avoid plastic deformation of the Rolling bearing running surfaces additionally arranged several sliding bodies as a result of axial load surges are whose dimension in the axial direction is slightly smaller than the diameter der'Wälzkörper, so that they have a large area compared to the rolling elements only when axial load shocks occur and because of the elastic deformability of the Rolling bearing running surfaces rest against the rolling bearing running surfaces before their elastic ones Deformation can change into a plastic deformation.
Anhand zweier in der Zeichnung dargestellter Ausführungsbeispiele sei die Erfindung erläutert. Während in Figur 1 der Käfig eines Wälzlagers mit rollenförmigen Wälzkörpern dargestellt ist, zeigt Figur 3 einen Käfig mit kugelförmigen Wälzkörpern. In den Figuren 2 und 4 ist jeweils ein Schnitt durch den Käfig des Wälzlagers gemäß Figur 1 bzw.On the basis of two exemplary embodiments shown in the drawing the invention is explained. While in Figure 1, the cage of a roller bearing with roller-shaped Rolling elements is shown, Figure 3 shows a cage with spherical rolling elements. FIGS. 2 and 4 each show a section through the cage of the roller bearing according to FIG Figure 1 resp.
gemäß Figur 3 dargestellt.shown in FIG.
Im Käfig 1 gemäß Figur 1 sind abwechselnd je drei rollenförmige Wälzkörper 2 und ein scheibenförmiger Gleitkörper 3 angeordnet. Die Rollen bzw. Nadeln 2 laufen bekanntlich auf den Laufflächen von nicht dargestellten Wälzlager-Ringen. Diese Laufflächen sind im allgemeinen einsatzgehärtet. Beim Auftreten großer Belastungsstößewerden die Lagerringe fest an die Rollen bzw. Nadeln 2 gepreßt und verformen sich dabei etwas. Die Dicke der Scheiben 3 ist nun so bemessen, daß sich die Lagerringe bei einem derartigen Belastungsstoß an die Scheibe 7 anlegen, bevor aus der elastischen Verformung der Lagerringe eine plastische, d.h. bleibende Verformung wird. Da die Fläche der Scheiben 3 erheblich größer ist als die Auflagefläche aer Rollen bzw. Nadeln 2, ist die Flächenpressung an diesen Auflageflächen erheblich geringer. Bei Entfernung der Stoßbelastung kann die elastische Verformung der Lagerringe wieder zurückfedern. Man erkennt, daß durch die erfindungsdungsgemäß vorgesehenen Gleitkörper 3 verhindert wird, daß eine bleibende Verformung, d.h. eine Brinellierung, stattfindet.In the cage 1 according to FIG. 1 there are alternating three roller-shaped rolling elements 2 and a disk-shaped sliding body 3 are arranged. The rollers or needles 2 run as is known on the running surfaces of rolling bearing rings, not shown. These Treads are generally case hardened. If large impact loads occur the bearing rings are pressed firmly against the rollers or needles 2 and deform in the process some. The thickness of the discs 3 is now such that the bearing rings at apply such a load shock to the disc 7 before leaving the elastic Deformation of the bearing rings becomes a plastic, i.e. permanent deformation. Since the The area of the discs 3 is considerably larger than the contact area of the rollers or Needles 2, the surface pressure on these bearing surfaces is considerably lower. at Removal of the shock load can restore the elastic deformation of the bearing rings spring back. It can be seen that according to the invention provided Sliding body 3 is prevented that a permanent deformation, i.e. a Brinellierung, takes place.
Im Käfig gemäß Figur 3 sind abwechselnd drei kugelförmige Wälzkörper 2 und ein toroidförmiger Gleitkörper 3 vorgesehen. Der Durchmesser der als Toroidabschnitte ausgebildetenGleitkörper 3 ist wiederum etwas geringer als der Durchmesser der Kugeln 2. Das wiederum hat zur Folge, daß die toroidförmigen Gleitkörper 3 sich während des normalen Betriebes lediglich gleitend innerhalb des Käfigs mit bewegen. Irgendwelche Kräfte werden von ihnen jedoch nicht aufgenommen. Erst wenn eine größere Stoßbelastung auf den Käfig ausgeübt wird, legen sich die Wälzlager-Ringe wegen ihrer elastischen Verformung an die Gleitkörper 3 an und stützen sich auf ihnen ab. Da die Auflagefläche dieser Gleitkörper erheblich gröBer ist als die Auflagefläche der Kugeln 3, ist die Flächenpressung an diesen Auflageflächen entsprechend gering. Eine bleibende Verformung, d.h. eine Brineilierung, wird dadurch verhindert.In the cage according to FIG. 3 there are alternating three spherical rolling elements 2 and a toroidal sliding body 3 is provided. The diameter of the toroidal sections formed sliding body 3 is again somewhat smaller than the diameter of the balls 2. This in turn has the consequence that the toroidal sliding body 3 is during during normal operation only move within the cage in a sliding manner. Any However, forces are not absorbed by them. Only when a greater shock load is exerted on the cage, the rolling bearing rings because of their elasticity Deformation to the sliding body 3 and are based on them. As the support surface this sliding body is considerably larger than the bearing surface of the balls 3 is the surface pressure on these bearing surfaces is correspondingly low. A lasting one This prevents deformation, i.e. brineing.
Die erfindungsgemäßen Äxialwälzlager sind insbesondere für solche Vorrichtungen vorgesehen, die mit relativ niedrigen Drehzahlen arbeiten. I)ie Gefahr eines Verklemmens oder Verkantens der Gleitkörper 3 besteht also nicht.The axial roller bearings according to the invention are particularly suitable for such Devices are provided that operate at relatively low speeds. I) the danger there is no jamming or tilting of the sliding body 3.
In den Ausführungsbeispielen der Wälzlager-Käfige sind abwechselnd je drei Wälzkörper und ein Gleitkörper dargestellt. Diese Anordnung ist jedoch nicht zwingend. Genauso gut könnten abwechselnd zwei oder vier Wälzkörper und ein Gleitkörper oder eine ähnliche Kombination vorgesehen werden. Entscheidend ist, daß die Auflagefläche der Gleitkörper im Vergleich zur Auflagefläche der Wälzkörper so groß ist, daß eine Brinellierung verhindert wird.In the exemplary embodiments the roller bearing cages are alternating three rolling elements and one sliding element each are shown. However, this arrangement is not imperative. Two or four rolling elements and a sliding element could just as well alternate or a similar combination is provided will. Decisive is that the bearing surface of the sliding bodies compared to the bearing surface of the rolling bodies is large enough to prevent brinelling.
