BeschreibungDescription
LageranordnungBearing arrangement
Die Erfindung betrifft eine Lageranordnung, insbesondere für eine Druckmaschine, bestehend aus mindestens einem Innenring, einem Außenring und einer Vielzahl von zwischen Innenring und Außenring angeordneten Wälzkörpern, mit der ein Wellenelement gegenüber einem Gehäuse drehbar gelagert wird, wobei der Außenring einen seitlichen Befestigungsflansch aufweist, mit dem er an dem Gehäuse festlegbar ist.The invention relates to a bearing arrangement, in particular for a printing machine, consisting of at least one inner ring, one outer ring and a plurality of rolling elements arranged between the inner ring and the outer ring, with which a shaft element is rotatably mounted relative to a housing, wherein the outer ring has a lateral fastening flange with which it can be fixed to the housing.
Lageranordnungen der gattungsgemäßen Art sind im Stand der Technik insbesondere bei Druckmaschinen bekannt. Das Lager ist mit einem seitlichen Flansch ausgestattet, mittels dem es in einem Gehäuse zunächst positioniert und dann - mit entsprechenden Schrauben - relativ zu diesem festgelegt wird.Bearing arrangements of the generic type are known in the state of the art, particularly in printing machines. The bearing is equipped with a lateral flange, by means of which it is first positioned in a housing and then - with appropriate screws - fixed relative to it.
Eine präzise Positionierung der Lagereinheit relativ zum Gehäuse wird dabei durch enge Passungen bewerkstelligt, was jedoch zum einen einen relativ hohen Fertigungsaufwand bedeutet und zum anderen nur eine bedingte Austauschbarkeit unterschiedlicher Flanschlagerungen untereinander aufgrund der immer vorhandenen Toleranzen bedingt.Precise positioning of the bearing unit relative to the housing is achieved by tight fits, which, however, means a relatively high manufacturing effort on the one hand and, on the other hand, only a limited interchangeability of different flange bearings with each other due to the tolerances that are always present.
Der Erfindung liegt daher die Aufgabe zugrunde, eine Flanschlagerung der eingangs genannten Art, insbesondere für Druckmaschinen, derart weiterzubilden, daß es möglich ist, ohne enge Passungen oder andere aufwendige Maßnahmen eine präzise Positionierung der Flanschlagereinheit in der Gehäusebohrung zu bewerkstelligen, ohne daß es auf eine extrem präzise Fertigung von Gehäusebohrung und Lageraußenring ankommen muß.The invention is therefore based on the object of developing a flange bearing of the type mentioned at the outset, in particular for printing machines, in such a way that it is possible to achieve precise positioning of the flange bearing unit in the housing bore without tight fits or other complex measures, without the need for extremely precise manufacturing of the housing bore and bearing outer ring.
Die Lösung dieser Aufgabe durch die Erfindung ist dadurch gekennzeichnet, daß zwischen Außenring und Gehäuse und/oder zwischen Innenring und dem zu lagernden Wellenelement mindestens drei über den Umfang verteilte Zentrierelemente in Form je eines Wälzkörpers angeordnet sind.The solution to this problem by the invention is characterized in that at least three centering elements in the form of a rolling element each are arranged between the outer ring and the housing and/or between the inner ring and the shaft element to be supported.
Bevorzugt sind die zentrierenden Wälzkörper gleichmäßig über den Umfang des Außenrings bzw. Innenrings verteilt. Weiterhin kann mit Vorteil vorgesehen werden, daß die Wälzkörper in einer Laufbahn oder in einer Nut geführt werden, die in den Außen- oder Innenumfang des Innen- oder Außenrings eingearbeitet sind.Preferably, the centering rolling elements are evenly distributed over the circumference of the outer ring or inner ring. Furthermore, it can advantageously be provided that the rolling elements are guided in a raceway or in a groove that is machined into the outer or inner circumference of the inner or outer ring.
Gemäß einer weiteren Fortbildung ist vorgesehen, daß zwischen dem Außenring und dem Gehäuse und/oder zwischen dem Innenring und dem zu lagernden Wellenelement eine Dichtung angeordnet ist.According to a further development, it is provided that a seal is arranged between the outer ring and the housing and/or between the inner ring and the shaft element to be supported.
Die zur Zentrierung der Lagereinheit eingesetzten Wälzkörper sind bevorzugt Kugeln. Die Lageranordnung selber kann in Achsrichtung mehrere Wälzkörperreihen nebeneinander aufweisen.The rolling elements used to center the bearing unit are preferably balls. The bearing arrangement itself can have several rows of rolling elements next to each other in the axial direction.
In der Zeichnung ist ein Ausfuhrungsbeispiel der erfindungsgemäßen Lageranordnung dargestellt. Die einzige Figur zeigt schematisch den Schnitt durch eine Flanschlagereinheit.The drawing shows an exemplary embodiment of the bearing arrangement according to the invention. The single figure shows a schematic section through a flange bearing unit.
Die Lageranordnung weist einen Innenring 1 sowie einen Außenring 2 auf, zwischen denen Wälzkörper 3 in bekannter Art und Weise dafür sorgen, daß Innenring und Außenring zueinander drehbar angeordnet sind. Mit der Lageranordnung soll ein Wellenelement 4 (Wellenzapfen) einer Druckmaschinenwalze 14 relativ zu einem Gehäuse 5 gelagert werden. Hierzu weist der Außenring 2 einen seitlichen Befestigungsflansch 6 auf, mit dem er über Schrauben am Gehäuse 5 festgelegt werden kann.The bearing arrangement has an inner ring 1 and an outer ring 2, between which rolling elements 3 ensure in a known manner that the inner ring and outer ring are arranged so that they can rotate relative to one another. The bearing arrangement is intended to support a shaft element 4 (shaft journal) of a printing press roller 14 relative to a housing 5. For this purpose, the outer ring 2 has a lateral fastening flange 6 with which it can be secured to the housing 5 using screws.
Der Außenumfang 12 des Außenrings 2 weist dabei in bezug auf die Aumahmebohrung 11 für das Lager im Gehäuse 5 Spiel auf, so daß es - vor dem Anziehen der Befestigungsschrauben, mit denen der Befestigungsflansch 6 am Gehäuse 5 festgelegt wird - möglich ist, die Lageranordnung in gewissem Umfang radial zu verschieben und so zu positionieren, daß sie den zu lagernden Wellenzapfen 4 genau zentrisch umfaßt. Zum zentrischen Einrichten der Lageranordnung sind Kugeln 7, 8, 9, 10 vorgesehen, die entweder zwischen Außenring 2 und Gehäuse 5 und/oder zwischen Innenring 1 und Wellenzapfen 4 angeordnet sind. Dabei sind vier Alternativ-Lösungen in der Figur dargestellt; in der Regel reicht es aus, daß nur eine Art von Kugeln 7, 8, 9 oder 10 vorgesehen wird.The outer circumference 12 of the outer ring 2 has play in relation to the receiving bore 11 for the bearing in the housing 5, so that - before tightening the fastening screws with which the fastening flange 6 is fixed to the housing 5 - it is possible to move the bearing arrangement radially to a certain extent and to position it so that it surrounds the shaft journal 4 to be supported exactly centrally. Balls 7, 8, 9, 10 are provided for centrically setting up the bearing arrangement, which are arranged either between the outer ring 2 and the housing 5 and/or between the inner ring 1 and the shaft journal 4. Four alternative solutions are shown in the figure; as a rule, it is sufficient to provide only one type of ball 7, 8, 9 or 10.
Zur genauen Führung der Kugeln können in den Innen- bzw. Außenring Laufbahnen 16 oder Nuten 17 eingearbeitet sein, so daß die Kugeln 7, 8, 9, 10 in definierter Weise abrollen können. Des weiteren kann vorgesehen werden, daß der sich zwischen der Aumahmebohrung 11 des Gehäuses 5 und der radialen Außenfläche 12 des Außenrings 2 ergebende Spalt durch eine Dichtung 15 abgedichtet wird.For precise guidance of the balls, raceways 16 or grooves 17 can be incorporated into the inner or outer ring so that the balls 7, 8, 9, 10 can roll in a defined manner. Furthermore, it can be provided that the gap resulting between the receiving bore 11 of the housing 5 and the radial outer surface 12 of the outer ring 2 is sealed by a seal 15.
Wie weiter zu erkennen ist, ist die Druckmaschinenwalze 14 an einem Flansch 13 des Innenrings 1 festgelegt.As can be further seen, the printing press roller 14 is fixed to a flange 13 of the inner ring 1.
Zum Zentrieren des Lagers ist es in der Regel ausreichend, daß drei gleichmäßig über den Umfang verteilte Kugeln 7, 8, 9 oder 10 vorgesehen werden, bevor die Befestigungsschrauben des Befestigungsflansches 6 angezogen werden und so die Lageranordnung relativ zum Gehäuse 5 festgelegt ist. Die Kugeln 7, 8, 9, 10 dienen dann nicht mehr zum Übertragen der Kräfte; der Kraftfluß erfolgt vielmehr von der Druckmaschinenwalze 14 über den Flansch 13 des Innenrings 1 (oder über die Verschraubung; siehe untere Figurenhälfte) und den Innenring 1, die Wälzkörper 3 und den Außenring 2 über den Befestigungsflansch 6 bis in das Gehäuse 5.To center the bearing, it is usually sufficient to provide three balls 7, 8, 9 or 10 evenly distributed around the circumference before tightening the fastening screws of the fastening flange 6 and thus fixing the bearing arrangement relative to the housing 5. The balls 7, 8, 9, 10 then no longer serve to transmit the forces; the force flow instead takes place from the printing press roller 14 via the flange 13 of the inner ring 1 (or via the screw connection; see lower half of the figure) and the inner ring 1, the rolling elements 3 and the outer ring 2 via the fastening flange 6 into the housing 5.
Mit der vorgeschlagenen Maßnahme ist es möglich, grob tolerierte Lagerringe einzusetzen, die dann erst in der Druckmaschine exakt zentriert werden. Der Herstellungsaufwand für derartige Lagereinheiten wird damit erheblich verringert.The proposed measure makes it possible to use roughly toleranced bearing rings that are then precisely centered in the printing machine. This significantly reduces the manufacturing effort for such bearing units.
