Abstract

The combined radial and thrust rolling bearing has an inner race of rectangular cross section. The rolling elements for the rradial loads are fitted between the outer and inner races. Thrust is accommodated by rolling elements on both end faces of the inner race. The inner race (1) has circumferential slots (13) on its cylindrical outside surface. The slots are open towards the outer race (2) and the thrust rollers (4) are in contact with the end faces of the inner race which can yield due to presence of the slots. The flexibility of the contact face on the inner race is equal to that of the thrust plates.

Description

Radial-Axial-Wälzlager Radial-axial rolling bearings

Die Erfindung betrifft ein Radial-Axial-Wälzlager, bestehend aus einem Laufring mit rechteckigem Querschnitt, zu dem koaxial und mit radialem Abstand eine Laufhülse angeordnet ist, zwischen denen Wälzkörper zur Radialkraftaufnahme abrollen, und bestehend aus zwei Kränzen in Käfigen aufgenommener Rollen zur Axialkraftaufnahme, die einerseits an den Stirnflächen des Laufringes und andererseits an Laufscheiben abrollen, die dicht gegen die Stirnflächen der Laufhülse angelegt sind.The invention relates to a radial-axial roller bearing, consisting of a Running ring with a rectangular cross-section, to which one is coaxial and radially spaced Running sleeve is arranged, between which rolling elements roll to absorb radial forces, and consisting of two cage-mounted rollers to absorb axial forces, on the one hand on the end faces of the raceway and on the other hand on running disks unroll, which are placed tightly against the end faces of the barrel.

Derartige bekannte Wälzlager dienen dazu, Wellen, Gewindespindeln oder dergleichen sowohl radial zu lagern, als auch gleichzeitig axial in beiden Richtungen sehr exakt zu positionieren und spielfrei in ihrer Einbaulage zu halten. Zu diesem Zweck müssen die Einzelteile derartiger Lager mit äußerst großer Genauigkeit hergestellt werden. Nur auf diese Weise läßt sich die erforderliche hohe Starrheit derartiger Lager erzielen. In vielen Fällen ist jedoch eine solche extreme Starrheit derartiger Lager nicht erforderlich, so daß sich in diesen Fällen die hohen Herstellungskosten der bekannten Lager nicht rechtfertigen lassen.Known roller bearings of this type are used to drive shafts and threaded spindles or the like to be supported both radially and axially in both at the same time To position directions very precisely and to keep them in their installation position without play. For this purpose, the individual parts of such bearings must be extremely accurate getting produced. Only in this way can the required high rigidity achieve such bearings. However, in many cases there is such extreme rigidity Such bearings are not required, so that in these cases the high manufacturing costs of the known camp can not be justified.

Der Erfindung liegt deshalb die Aufgabe zugrunde, ein solches Lager mit verringerter Starrheit in axialer Richtung auszuführen, um dadurch größere Herstellungstoleranzen überbrücken zu können.The invention is therefore based on the object of such camp Execute with reduced rigidity in the axial direction, thereby greater manufacturing tolerances to be able to bridge.

Die Erfindung löst diese Aufgabe dadurch, daß sich einerseits die Laufscheiben an ihren der Laufhülse abgewandten Stirnseiten nur über einen Teilbereich ihrer radialen Erstreckung an angrenzenden Bauteilen abstützen und daß andererseits der Laufring im Abstand von seinen Stirnflächen mit wenigstens einem zur Laufhülse hin offenen Radialschlitz versehen ist, durch den die Abschnitte des Laufringes, an deren Stirnflächen die Rollen zur Axialkraftaufnahme abrollen, wenigstens annähernd die gleiche Federkonstante erhalten wie die zugeordneten Laufscheiben. Auf diese Weise können die Laufscheiben einerseits und die ihnen gegenüberliegenden, durch den Radialschlitz begrenzte Teile des Laufringes bei axialer Verspannung des Lagers um einen gewissen Betrag federnd ausweichen und dadurch Herstelltoleranzen ausgleichen.The invention solves this problem in that on the one hand the Running disks on their end faces facing away from the running sleeve only over a partial area support their radial extent on adjacent components and that on the other hand the raceway at a distance from its end faces with at least one to the barrel sleeve is provided with an open radial slot through which the sections of the race, at the end faces of which the rollers for absorbing axial force roll, at least approximately get the same spring constant as the associated pulleys. To this Way, the pulleys on the one hand and those opposite them through the radial slot limited parts of the race with axial bracing of the bearing Dodge resiliently by a certain amount and thereby compensate for manufacturing tolerances.

Durch geeignete konstruktive Ausbildung, nämlich Wahl des axialen Abstandes der Radialschlitze von den Stirnflächen des Laufringes, radiale Tiefe der Radialschlitze und so weiter kar£i die angestrebte Federkonstante bestimmt werden.By suitable structural design, namely choice of the axial Distance of the radial slots from the end faces of the race, radial depth of the radial slots and so on, the desired spring constant can be determined.

Will man beispielsweise die Endbereiche des Laufringes, gegen welche die Rollen zur Axialkraftaufnahme anliegen, weicher gestalten, so kann man den Abstand zwischen den Stirnflächen des Laufringes und dem geschlossenen Ende eines Radialschlitzes zum Beispiel durch ringförmige Nuten an den Stirnflächen des Laufringes verringern.For example, if you want the end areas of the raceway against which the rollers for absorbing axial force are in contact, make them softer, so you can adjust the distance between the end faces of the raceway and the closed end of a radial slot for example, by means of annular grooves on the end faces of the raceway.

In den Zeichnungen sind Ausführungsbeispiele der Erfindung jeweils im Längsschnitt dargestellt.In the drawings, there are exemplary embodiments of the invention, respectively shown in longitudinal section.

Das in Figur 1 dargestellte Lager besteht aus dem Laufring 1, der Laufhülse 2 und den dazwischen abrollenden Rollen 3.The bearing shown in Figure 1 consists of the race 1, the Running sleeve 2 and the rollers 3 rolling in between.

Zur Axialkraftaufnahme sind die Rollen 4, die in Käfigen 5 geführt sind, vorgesehen. Diese rollen einerseits an den Stirnflächen des Laufringes 1 und andererseits an Laufscheiben 6 ab, die stirnseitig dicht gegen die Laufhülse 2 angelegt sind. Die Laufhülse 2 und die beiden gegen diese anliegenden Laufscheiben 6 sind in einer Bohrung des Gehäuses 7 untergebracht und durch den Gehäusedeckel 8 spielfrei gegeneinander verspannt. Der Laufring 1 sitzt auf der Welle 9 und liegt einerseits gegen den Wellenbund 10 an. Auf der anderen Seite wird er durch die Mutter 11 und die Distanzhülse 12 so beaufschlagt, daß er spielfrei und unter Vorspannung gegen den Wellenbund 10 anliegt.The rollers 4, which are in cages 5 guided are provided. These roll on the one hand on the end faces of the race 1 and on the other hand, on running disks 6, which are placed tightly against the running sleeve 2 on the end face are. The barrel sleeve 2 and the two running disks 6 resting against them are housed in a bore of the housing 7 and free of play through the housing cover 8 braced against each other. The race 1 sits on the shaft 9 and lies on the one hand against the shaft collar 10. On the other hand, he becomes 11 and through the mother the spacer sleeve 12 is applied so that it is backlash-free and biased against the shaft collar 10 is applied.

Um dieser Lagerung die gewünschte radiale Weichheit zu geben, sind die Laufscheiben 6 so ausgeführt, daß sie sich an ihrer dem eigentlichen Lager abgewandten Seite nur über einen Teilbereich ihrer radialen Erstreckung an den angrenzenden Bauteilen, nämlich dem Gehäuse 7 einerseits und dem Gehäusedeckel 8 andererseits abstützen. Auf diese Weise ist es möglich, daß die Laufscheiben unter axialer Belastung um einen bestimmten Betrag durchfedern. Um zu gewährleisten, daß an den Rollen 4 keine Kantenbelastungen auftreten, sind an dem Laufring 1 zwei Radialschlitze 13 vorgesehen, die den Endbereichen des Laufringes 1, an denen die Rollen 4 abwälzen, eine annähernd gleiche Federkonstante geben wie die der Laufscheiben 6.In order to give this storage the desired radial softness, are the running disks 6 designed so that they face away from the actual bearing Side only over part of its radial extent to the adjacent Components, namely the housing 7 on the one hand and the housing cover 8 on the other hand prop up. In this way it is possible that the running disks are under axial load deflect by a certain amount. To ensure that the rollers 4 no edge loads occur, there are two radial slots 13 on the race 1 provided that the end regions of the race 1, on which the rollers 4 roll, give a spring constant that is approximately the same as that of the running disks 6.

Die in Figur 2 dargestellte Lagerausführung unterscheidet sich von der nach Figur 1 im wesentlichen nur dadurch, daß der Laufring 14 nur einen mittigen Radialschlitz 15 aufweist. Die Radiallagerung erfolgt in diesem Falle durch zwei Rollenkränze 16, die beiderseits des Radialschlitzes 15 auf dem Laufring 14 abrollen.The bearing design shown in Figure 2 differs from that of Figure 1 essentially only in that the race 14 is only a central one Has radial slot 15. In this case, there are two radial bearings Roller rings 16, which roll on both sides of the radial slot 15 on the race 14.

Die Figur 3 zeigt einen gegenüber Figur 2 abgewandelten Laufring 17, bei dem eine geringere axiale Starrheit durch die ringförmigen Nuten 18 in den Stirnflchen des Laufringes erzielt wird.Figure 3 shows a modified compared to Figure 2 race 17, in which a lower axial rigidity due to the annular grooves 18 in the end faces of the race is achieved.

Das Lager nach Figur 4 entspricht schließlich in allen wesentlichen Einzelheiten dem nach Figur 1 wobei allerdings in radialer Richtung gesehen innen und außen vertauscht sind. Der Laufring 19 ist hier als Außenlaufring ausgeführt, der sich über die Rollen 20 auf der als Innenring ausgeführten Laufhülse 21 abstützt. An dem Laufring 19 sind zwei Radialschlitze 22 vorgesehen. An den Stirnseiten der Laufhülse 21 stützen sich die Laufscheiben 23 ab, an denen die Rollen 24 abwälzen, die in Käfigen 25 geführt sind. In Abwandlung der Figur 1 ist in diesem Beispiel auch für die Rollen 20 ein Käfig 26 vorgesehen.Finally, the bearing according to FIG. 4 corresponds in all essentials Details that according to Figure 1, but seen in the radial direction inside and are swapped outside. The race 19 is designed here as an outer race, which is supported via the rollers 20 on the barrel sleeve 21 designed as an inner ring. Two radial slots 22 are provided on the race 19. At the front of the Running sleeve 21 is supported by the running disks 23 on which the rollers 24 roll, which are carried in cages 25. In this example, a modification of FIG A cage 26 is also provided for the rollers 20.
