Description
Lagervorrichtung mit Drahtkugellagern Die Erfindung bezieht sich auf eine Lagervorrich tung mit Drahtkugellagern, vornehmlich für sehr hohe Axialdrücke.
Um sehr hohe Axialdrücke aufnehmen zu können, wurden bisher bei solchen Lagervorrichtungen meh rere zwei- oder mehrreihige Drahtkugellager neben einander eingesetzt. Durch diese Nebeneinander anordnung trat zwangläufig in der horizontalen Aus dehnung des Lagers ein grosser Platzbedarf auf. Da durch wurde die Anwendung mehrreihiger Kugel lager erschwert und in manchen Fällen sogar unmög lich gemacht.
Die Erfindung hat sich die Aufgabe gestellt, unter Aufrechterhaltung aller vorteilhaften Eigenschaften eines Drahtkugellagers auch die Möglichkeit zu schaffen, auch Lagervorrichtungen, bei denen eine Drehung unter schweren und schwersten Axialdrücken vor sich gehen rnuss, wie z. B. an Tiefbohrgestängen, mit Drahtkugellagern versehen zu können, ohne dass dazu in horizontaler Ausdehnung ein grösserer Platz bedarf nötig ist.
Zu diesem Zweck werden gemäss der Erfindung mehrere ein- oder mehrreihige Drahtkugellager un abhängig voneinander übereinander angeordnet, wo bei die Belastung in einer Richtung von einem Innen ring über die Drahtkugellager auf einen Aussenring übertragen werden, wobei zur Übertragung der Be lastung an beiden Ringen stufenartig abgesetzte Schul tern vorgesehen sind. Das Tragen aller unabhängig übereinanderliegenden Drahtkugelreihen wird dadurch erzielt, dass sich die Laufdrähte bei Überlastung so lange einwalzen, bis sämtliche Kugelreihen zum Tra gen kommen und somit die zulässige Belastbarkeit erreicht ist.
Ein Vorteil einer Ausführungsform mit mehr reihigen Drahtkugellagern ist in der Art der Schmie rung zu sehen, die vorzugsweise als Durchlaufschmie- rung ausgebildet werden kann, insofern, als bei einer Ölschmierung für hohe Geschwindigkeiten das Öl durch die zur Horizontalen treppenartig etwas ab gesetzten Kugelreihen hindurchläuft und auf den darunter befindlichen Tragring gelangt, der in ent gegengesetztem Gefälle nach dem Aussenring zu ab fällt. Darauf gelangt das Öl zu den Kugeln des nächsten, darunter liegenden Lagers. Dabei wird ausserdem die von dem sich drehenden Tragring auf das Öl ausgeübte Zentrifugalkraft ausgenutzt, um den gleichmässigen Fluss des Öls zu fördern.
Infolge des dabei in den Kugelreihen jedes Lagers vorhan denen Gefälles und den Abschrägungen der oberen Fläche der Tragringe fliesst das Schmieröl durch alle Kugelreihen nacheinander hindurch und gewähr leistet eine gleichmässige Schmierung aller Kugel reihen.
Zwei Ausführungsbeispiele des Erfindungsgegen standes sind in der Zeichnung wiedergegeben.
Es zeigen: Fig. 1 einen lotrechten Schnitt durch eine Hälfte eines dreistufigen Beispiels mit einreihigen Draht kugellagern zur Lagerung eines Bohrgestänges, Fig. 2 einen gleichen Schnitt wie Fig. 1 durch eine Hälfte eines Beispiels mit dreistufigen, dreireihigen Drahtkugellagern für besonders hohe Axiallasten.
In Fig. 1 sind mit 1 die Kugeln bezeichnet, die auf vier Laufdrähten 2 entlangrollen. 3 sind die Tragringe, in denen die Laufdrähte eingebettet sind. In Fig. 1 sind vier einreihige Drahtkugellager 4, 5, 6, 7 übereinander angeordnet, wobei die Lager 4 und 5 als Wechsellager ausgebildet sind. Das Lager 4 übernimmt die auf der Zeichnung nach oben wirken den Kräfte, während die Lager 5, 6 und 7 die nach unten wirkenden Belastungen gleichmässig verteilt auf nehmen.
Infolge dieser Verteilung der Kräfte wird ein Vorteil erzielt, und zwar können die Lager leich- ter ausgeführt sein. Von dem das Bohrgestänge aufnehmenden Innenring 8 wird die Last über die Schultern 9 und 10 sowie über die Schulter 20 an dem am Innenring 8 befindlichen Bund 8' auf die Drahtkugellager 5, 6 und 7 in Richtung der Auf lage 14 übertragen. Bei dieser Ausführung können ausser den reinen Axiallasten in beiden Richtungen auch Radialkräfte und Momentbelastungen auf genommen werden. Die Lager übertragen die Last über die Schultern 12 und den Unterring 13 auf den zur Aufnahme der Belastung dienenden Aussenring 15.
In Fig. 2 bildet jede Stufe ein dreireihiges Draht kugellager 23, 24, 25. Die Belastung wird von dem mit Schultern 9' und 10' ausgerüsteten Innenring 8" auf die jeweiligen Tragringe 16, 17, 18 übertragen. Die Gegenaufnahme bildet der Aussenring 15", der ebenfalls mit Schultern 12' versehen ist, und über die Aufnahmeringe 19, 20, 21 die Belastung auf nimmt.
Durch Nachsetzen der Schultern 9 und 10 bzw. 9' und 10' ist eine Voreinstellung der gleichmässigen Verteilung der Last bei der Montage möglich. Vor her kann durch belastetes Drehen mit weniger Ku geln in jeder Laufbahn eine Verteilung der Last erzielt werden. Die Feineinstellung erfolgt selbst tätig durch das Einwalzen der Kugeln in ihre Lauf drähte.
Zum Transport und zum Einbau ist ein Flansch ring 22 vorgesehen, der an den Innenring 8" an geschraubt wird und das Lager gegen Abheben sichert und dadurch das Herausfallen der Kugeln verhindert. Bei beiden Beispielen sind die Schultern der Ringe stufenartig abgesetzt.
Bearing device with wire ball bearings The invention relates to a Lagervorrich device with wire ball bearings, primarily for very high axial pressures.
In order to be able to absorb very high axial pressures, several two- or multi-row wire ball bearings have been used next to each other in such storage devices. This side-by-side arrangement inevitably required a large amount of space in the horizontal expansion of the warehouse. Since the use of multi-row ball bearings was made more difficult and in some cases even made impossible.
The invention has set itself the task of maintaining all the advantageous properties of a wire ball bearing and creating the possibility of also bearing devices in which a rotation under heavy and extremely heavy axial pressures go ahead, such. B. on deep drilling rods to be able to provide wire ball bearings without the need for a larger space in the horizontal extension.
For this purpose, according to the invention, several single or multi-row wire ball bearings are arranged one above the other, where the load is transferred in one direction from an inner ring via the wire ball bearings to an outer ring, with the transfer of the load being stepped on both rings Shoulders are provided. The carrying of all rows of wire balls lying independently on top of one another is achieved by the fact that the running wires roll in when overloaded until all rows of balls come to bear and thus the permissible load capacity is reached.
An advantage of an embodiment with multi-row wire ball bearings can be seen in the type of lubrication, which can preferably be designed as continuous lubrication, insofar as with oil lubrication for high speeds the oil runs through the rows of balls, which are somewhat offset from the horizontal, and reaches the support ring below, which falls in the opposite slope towards the outer ring. The oil then reaches the balls of the next bearing below. The centrifugal force exerted on the oil by the rotating support ring is also used to promote the even flow of the oil.
As a result of the incline in the rows of balls of each bearing and the bevels on the upper surface of the support rings, the lubricating oil flows through all rows of balls one after the other and ensures uniform lubrication of all rows of balls.
Two embodiments of the subject invention are shown in the drawing.
1 shows a vertical section through one half of a three-stage example with single-row wire ball bearings for mounting a drill rod, FIG. 2 shows the same section as FIG. 1 through one half of an example with three-stage, three-row wire ball bearings for particularly high axial loads.
In FIG. 1, 1 denotes the balls which roll along four running wires 2. 3 are the support rings in which the running wires are embedded. In Fig. 1, four single-row wire ball bearings 4, 5, 6, 7 are arranged one above the other, the bearings 4 and 5 being designed as interchangeable bearings. The bearing 4 takes over the forces acting upward on the drawing, while the bearings 5, 6 and 7 take the downward loads evenly distributed.
As a result of this distribution of forces, an advantage is achieved, namely that the bearings can be made lighter. From the inner ring 8 accommodating the drill pipe, the load is transmitted over the shoulders 9 and 10 and over the shoulder 20 on the collar 8 'located on the inner ring 8 to the wire ball bearings 5, 6 and 7 in the direction of the position 14. With this design, in addition to the pure axial loads in both directions, radial forces and moment loads can also be absorbed. The bearings transmit the load via the shoulders 12 and the lower ring 13 to the outer ring 15 used to absorb the load.
In FIG. 2, each step forms a three-row wire ball bearing 23, 24, 25. The load is transferred from the inner ring 8 ″, which is equipped with shoulders 9 'and 10', to the respective support rings 16, 17, 18. The outer ring 15 forms the counter-mount ", which is also provided with shoulders 12 ', and takes the load on the receiving rings 19, 20, 21.
By repositioning the shoulders 9 and 10 or 9 'and 10', it is possible to pre-set the even distribution of the load during assembly. Prior to that, a load distribution can be achieved with fewer balls in each career by turning under load. The fine adjustment is done by rolling the balls into their barrel wires.
A flange ring 22 is provided for transport and installation, which is screwed onto the inner ring 8 ″ and secures the bearing against lifting and thereby prevents the balls from falling out. In both examples, the shoulders of the rings are stepped off.
