Description

Es gibt im Maschinenbau gewisse Fälle, bei denen eine zu geringe Lagerreibung unerwünscht ist. So beobachtet man z. B. bei mit Wälzlagern ausgerüsteten Offsetzylindern, obwohl Rollenlager sehr hoher Genauigkeit verwendet werden, die fast spielfrei, mitunter sogar vollkommen spielfrei laufen, meist ein unsauberes Druckbild. Der Druck ist unscharf, die Farben fließen an den Rändern ineinander bzw. decken .am Rand nicht. Das, Zustandekommen des fehlerhaften Druckes wird auf die zu geringe Reibung der verwendeten Wälzlager zurückgeführt. Bei Ausrüstung der Offsetzylinder mit Gleitlagern, die ja mit größerer Reibung :behaftet sind, tritt dieser Fehler nämlich nicht auf.In mechanical engineering there are certain cases in which the bearing friction is too low is undesirable. So one observes z. B. with offset cylinders equipped with roller bearings, although very high accuracy roller bearings are used that are almost free of play, sometimes even run completely free of play, usually an unclean print image. Of the The print is fuzzy, the colors flow into one another or cover the edges Edge not. The occurrence of the faulty print is due to the insufficient The friction of the rolling bearings used is returned. When equipping the offset cylinder This error occurs with plain bearings, which are subject to greater friction namely not on.

Da man andererseits auf die Vorteile, die die Verwendung von Wälzlagern mit sich bringt, :nicht verzichten will, muß versucht werden, diesen Nachteil zu beseitigen, um so mehr, .als nicht :nur in dem angeführten Beispiel der Offsetzylinder, sondern in vielen anderen die gleichen oder ähnliche Anstände vorliegen.On the other hand, on the advantages of using rolling bearings brings with it: does not want to do without, one must try to avoid this disadvantage eliminate, all the more so than not: only in the example given the offset cylinder, but in many others the same or similar conditions exist.

Gegenstand der Erfindung .ist ein Wälzlager mit erhöhtem Rollwiderstand, wobei erfindungsgemäß der Käfig mit dem Rollkörpersatz gegenüber dem Rollbahnring bis zu einem gewissen Grad abgebremst wird. Erreicht wird dies. .durch folgende Maßnahmen A) Durch Abbremsen des Käfigs, indem .man denselben durch eine außerhalb des Lagers angebrachte Bremsvorrichtung, z. B. Bremsscheiben, am Lauf hindert und dadurch die Reibung in den Käfigtaschen erhöht.The subject of the invention is a rolling bearing with increased rolling resistance, wherein according to the invention the cage with the roller body set opposite the roller track ring is braked to a certain extent. This is achieved. .by the following Measures A) By braking the cage by .man the same through an outside the bearing mounted braking device, e.g. B. brake discs, prevents and this increases the friction in the cage pockets.

B) Durch Erhöhung des Rollwiderstandes der Rollkörper gegenüber den Rollbahnen, indem in einer oder beiden Rollbahnen eine oder mehrere Nuten angeordnet werden, in die elastisch nachgiebige Elemente, z. B. Bunaringe, eingelegt werden, welche um einen geringen Betrag über die Rollbahn vorstehen, so daß eine daupernde elastische Verformung der nachgiebigen Elemente beim Umlauf des Lagers und damit eine Erhöhung des Rollwiderstandes stattfindet.B) By increasing the rolling resistance of the rolling elements compared to the Runways by placing one or more grooves in one or both runways are, in the resilient elements such. B. buna rings, are inserted, which protrude by a small amount over the runway, so that a daupenden elastic deformation of the flexible elements during rotation of the bearing and thus an increase in rolling resistance takes place.

C) Schließlich ist es möglich, beide Maßnahmen A und B gleichzeitig anzuwenden.C) Finally, it is possible to take both measures A and B at the same time apply.

Abb. I der Zeichnung .stellt ein Ausführungsbeispiel wie unter A angegeben dar. Mit I ist das Wälzlager bezeichnet, 2 ist der Käfig. Die Käfigtaschen 3 sind in axialer Richtung länger als die Rollen 4, gegebenenfalls kann der Käfig 2 breiter als .das Wälzlager I ausgeführt werden. Die Stirnseiten 5 des Käfigs 2 gleiten an den stillstehenden Bremsringen 6 und 6a. Der Bremsring 6a ist verschiebbar angeordnet und wird durch Federn 7 gegen den Käfig 2 gedrückt, der ebenfalls axial verschiebbar ist und an .den Ring 6 zur Anlage kommt. Dadurch wird der Käfig 2 von den :beiden stillstehenden Ringen 6 und 6a je nach der Anpreßkraft der Federn 7 mehr oder weniger stark abgebremst.Fig. I of the drawing shows an embodiment as indicated under A. I denotes the roller bearing, 2 is the cage. The cage pockets 3 are longer than the rollers 4 in the axial direction; the cage 2 can optionally be wider as .the rolling bearing I are executed. The end faces 5 of the cage 2 slide on the stationary brake rings 6 and 6a. The brake ring 6a is arranged to be displaceable and is pressed by springs 7 against the cage 2, which is also axially displaceable is and at .den ring 6 comes to the plant. This makes cage 2 of the two stationary rings 6 and 6a depending on the pressing force of the springs 7 more or less strongly decelerated.

Abb. 2 zeigt ein Rollenlager, bei dem gemäß B in einem Rollbahnring eine Nut angebracht ist, :in die ein elastisch nachgiebiger Ring eingelegt ist. II ist der Außenring; 12 ist die im Außenring angebrachte Nut, 13 der elastisch nachgiebige Ring. Wie aus Abb. 3 ersichtlich, steht der Ring 13 über die Laufbahn vor. Die Rollen I4 drücken ihn :beim Abrollen im Außenring II zusammen. Durch die dabei aufgewendete Verformungsarbeit wird der Rollwiderstand des Lagers erhöht.Fig. 2 shows a roller bearing in which according to B in a raceway ring a groove is attached: in which an elastically resilient ring is inserted. II is the outer ring; 12 is the groove made in the outer ring, 13 is the elastic one yielding ring. As can be seen from Fig. 3, the ring 13 is above the raceway before. The rollers I4 compress it: when rolling in the outer ring II. Through the deformation work expended in the process increases the rolling resistance of the bearing.

Die Abbildungen sind nur als Beispiele anzusehen. Es sind auch andere Ausführungen möglich. So kann der Käfig am Umfang oder in der Bohrung abgebremst werden, wie auch die elastisch nachgiebigen Ringe sowohl mm Außenring als auch am Innenring angeordnet werden können.The figures are only to be viewed as examples. There are others too Executions possible. So the cage can be braked on the circumference or in the bore like the resilient rings, both mm outer ring and am Inner ring can be arranged.
