Description
Die Erfindung bezieht sich auf die Lagerung der Wälzlager für Hochleistungsgelenkkreuze Zapfen der Gelenkkreuze von Gelenkwellen, die zur übertragung von Drehmomenten dienen.The invention relates to the storage of roller bearings for high-performance articulated crosses Pins of the universal joints of cardan shafts, which are used to transmit torque.
Bei den Gelenkwellen müssen die Zapfen der Gelenkkreuze das Drehmoment übertragen. Wegen der hohen Belastung der Zapfenlager werden diese als Nadelwälzlager ausgebildet, und zwar entweder als Nadelwälzlager mit Käfigführung oder als vollnadeliges Lager. Nadellager mit Nadelkäfig sind nicht so stark belastbar wie vollnadelige Lager. Die letztgenannten Lager haben jedoch den Nachteil, daß insbesondere bei großen Beugungswinkeln der Gelenkwelle und langen Nadeln die Nadeln zum Schränken neigen, wodurch eine Zerstörung des Lagers eintritt.In the case of cardan shafts, the journals of the universal joints must provide the torque transfer. Because of the high load on the journal bearings, they are used as needle roller bearings designed, either as a needle roller bearing with a cage guide or as a needle roller bearing Camp. Needle roller bearings with a needle cage are not as resilient as full needle bearings Camp. However, the last-mentioned camps have the disadvantage that in particular at large bending angles of the cardan shaft and long needles the needles for setting tend, whereby a destruction of the bearing occurs.
Es ist zwar bereits bekannt, daß die Tragfähigkeit von hochbelasteten Lagern verbessert werden kann, wenn man Langrollen durch mehrere hintereinander angeordnete Kurzrollen ersetzt. In der praktischen Ausführung wird aber ein Käfig zur Führung der Kurzrollen für unerläßlich gehalten. Weiterhin ist ein Wälzlager bekannt, bei welchem ebenfalls die Langrollen durch mehrere hintereinanderliegende Kurzrollen ersetzt sind. Statt eines Käfigs hat man dort jedoch in der Stirnfläche jeder Kurzrolle einen Führungszapfen für die benachbarten Kurzrollen vorgesehen oder eine Kurzrollenreihe auf einen Stift aufgefädelt. Ferner sind Wälzlager für Hochleistungsgelenkkreuze bekannt, bei denen die Kurzrollen in Umfangsreihen unmittelbar nebeneinanderliegen. Bei ihnen ist jedoch jede Umfangsreihe von Kurzrollen durch einen Seitenbord geführt.It is already known that the load-bearing capacity of heavily loaded bearings can be improved if long rollers are replaced by several short rollers arranged one behind the other. In practice, however, a cage for guiding the short rolls is considered essential. Furthermore, a roller bearing is known in which the long rollers are also replaced by several short rollers one behind the other. Instead of a cage, however, a guide pin has been provided in the end face of each short roll for the adjacent short rolls or a row of short rolls has been threaded onto a pin. Rolling bearings for high-performance articulated crosses are also known in which the short rollers lie directly next to one another in circumferential rows. With them, however, each circumferential row of short rolls is passed through a side board.
Der Erfindung liegt nun die Aufgabe zugrunde, ein Wälzlagoer für Hochleistungsgelenkkreuze zu schaffen, das bei den dort auftretenden hohen Biegekräften eine maximale Tragfähigkeit hat.The invention is now based on the object of a roller bearing for high-performance articulated crosses to create a maximum load-bearing capacity with the high bending forces that occur there Has.
Ein Wälzlager für Hochleistungsgelenkkreuze nach der Erfindung ist gekennzeichnet durch die Kombination folgender für sich bekannter Merkmale: a) Zwischen Zapfen und Lagerbüchse. sind mehr als zwei Umfangsreihen von Kurzrollen angeordnet; b) in jeder Umfangsreihe liegen die Kurzrollen unmittelbar nebeneinander; c) nur die an den Enden des Lagers liegenden Umfangsreihen sind mittels eines seitlichen Führungsbordes geführt; d) die Kurzrollen jAer zwischen den Endreihen liegenden Umfangsreihe stützen sich in Achsricbtung des Lagers ausschließlich mit ebenen Stirnflächen an den Kurzrollen der benachbarten Reihe ab. Durch diese Kombination für sich bekannter Merkmale wird die Tragfähigkeit und damit auch die Lebensdauer des Wälzlagers für Hochleistungsgelenkkreuze beträchtlich vergrößert. Es wurde überraschenderweise festgestellt, daß trotz des Fehlens von Seitenborden für die mittleren Umfangsreihen kein Schränken der Kurzrollen auftritt, die mittleren Reihen also ausreichend vorr den Endreihen geführt werden.A roller bearing for high-performance articulated crosses according to the invention is characterized by the combination of the following features which are known per se: a) Between the journal and the bearing bush. there are more than two circumferential rows of short rolls; b) in each circumferential row, the short rolls lie directly next to one another; c) only the circumferential rows at the ends of the bearing are guided by means of a lateral guide rim; d) the short rolls of any circumferential row lying between the end rows are supported in the axial direction of the bearing exclusively with flat end faces on the short rolls of the adjacent row. This combination of features that are known per se increases the load-bearing capacity and thus also the service life of the roller bearing for high-performance articulated crosses. It was surprisingly found that, despite the lack of side rims for the middle circumferential rows, the short rolls are not set, so the middle rows are sufficiently guided in front of the end rows.
Vorzugsweise ist das in Umfangsrichtung gemessene Spiel zwischen den unmittelbar nebeneinanderliegenden Rollen so bemessen, daß die letzte Rolle unterVorspannung in dieLagQrbüchse einfedert. Dadurch ist die Handhabung der Lagerbüchs-e mit den eingestellten Rollen wesentlich erleichtert. Ein besonderer Vorteil dieser Ausführung ist es außerdem, daß die Rollen bezüglich ihrer zusammenpassenden Toleranz schon von der Herstellerfirma des Lagers auso,ewählt werden und daß diese Auswahl nicht dem Monteur in der Lokomotivfabrik od. dgl. überlassen wird.The play measured in the circumferential direction is preferably between the Measure directly adjacent rolls in such a way that the last roll is preloaded springs into the bearing bush. This makes it easier to handle the bearing bushes with the set roles much easier. A particular advantage of this design it is also that the roles are already in terms of their matching tolerance be selected by the manufacturer of the bearing and that this selection is not is left to the fitter in the locomotive factory or the like.
Um bei einer Abnutzung das Lager austauschen zu können, ohne das ganze Gelenkkreuz auswechseln zu müssen, ist es bekannt, auf dem Zapfen des Gelenkkreuzes einen inneren Lagerring aufzupressen. Da bei den auftretenden Biegebeanspruchungen der Zapfen die äußeren Enden der in den Endreihen liegenden Kurzrollen am stärksten belastet werden, wird gemäß einem weiteren Merkmal die Lebensdauer des Wälzlagers dadurch.erhöht, daß die Bohrung des inneren Lagerrings an den Enden im Bereich derRollenlauffläche miteinerflachenkonischen Erweiterung versehen wird. Dadurch kann der Lagerring in dem am höchsten belasteten Bereich etwas nachgeben. Die Erfindung wird im folgenden an Hand einer schematischen Zeichnung an einem Ausführungsbeispiel näher erläutert.In order to be able to replace the bearing in the event of wear without the whole It is known to have to replace the universal joint on the journal of the universal joint to press on an inner bearing ring. As with the bending stresses that occur the pin the outer ends of the short rolls lying in the end rows strongest are loaded, the life of the rolling bearing is according to a further feature in that the bore of the inner bearing ring is increased at the ends in the area of the roller running surface is provided with a flat-conical extension. This allows the bearing ring in give in to the most stressed area. The invention is in the following with reference to a schematic drawing of an embodiment explained in more detail.
In der Zeichnung ist ein Axialschnitt durch ein nach der Erfindung ausgebildetes Lager eines Kreuzgelenks dargestellt.In the drawing is an axial section through a according to the invention formed bearing of a universal joint shown.
In der Lagerbüchse 1 liegt am Boden eine Druckscheibe 2. Am Innenumf ang der Lagerbüchse 1 sind vier Reihen von Kurzrollen 3 zwischen den Borden 4 geführt, die gleichzeitig die Druckscheibe 2 in ihrer Lage am Boden der Lagerbüchse 1 halten. Die Lagerbüchse 1 ist nach außen abgeschlossen durch einen Staubschutzring4 und die Schmierstoffdichtung 6, die auch eine Einheit bilden können. Auf den Zapfen 7 ist ein Lagerring 8 aufgepreßt, der an beiden Enden, wie bei 10 angedeutet, eine leichte konische Erweiterung besitzt.In the bearing bush 1, a pressure plate lies on the ground 2. At the inner periphery of the bearing bush HS 1, four rows of short rollers 3 out between the rims 4, at the same time keep the pressure plate 2 in position on the bottom of the bearing bush. 1 The bearing bush 1 is closed to the outside by a dust protection ring 4 and the lubricant seal 6, which can also form a unit. A bearing ring 8 is pressed onto the pin 7 and has a slight conical widening at both ends, as indicated at 10.
Soll der Zapfen 7 des Gelenkkreuzes 9 mit einem neuen Lager versehen werden, so wird die Lagerbüchse 1 mit den von ihr gehaltenen Teilen 2 bis 6 abgezogen und dann der Zapfen 7 mit einem neuen Lagerring 8 versehen, worauf dann eine neue Lagerbüchse 1 mit zugehörigen Teilen 2 bis 6 zusammen eingebaut wird.If the pin 7 of the universal joint 9 is to be provided with a new bearing, the bearing bush 1 with the parts 2 to 6 held by it is withdrawn and then the pin 7 is provided with a new bearing ring 8 , whereupon a new bearing bush 1 with associated parts 2 to 6 are installed together.
