Description
Vorliegende Erfindung bezieht sich auf eine neue Ausbildung von zylindrischen Rollenlagern, insbesondere auf solche Lager, bei denen der eine Laufring aus einem Federlaufband besteht, dessen Außendurchmesser (nicht die Lauffläche) genau axial zum Laufzylinder konisch geschliffen ist, und in einer ungeteilten Hülse mit gleichem Gegenkonus aufgenommen wird, so daß eine Relativverschiebung zwischen Federband und Konushülse eine Regulierung des Lagerdurchmessers ermöglicht. Das besondere Merkmal der Neuheit dieses Lagers besteht darin, daß die Enden des konischen Federlaufbandes mittels zweier drehbarer Seitenscheiben abgefangen und gegeneinander verdreht werden können, um den Durchmesser des Laufbandes zu verändern und dadurch die Relativverschiebung zwischen LaufbandThe present invention relates to a new design of cylindrical Roller bearings, in particular on those bearings in which the one raceway consists of a spring belt exists whose outer diameter (not the running surface) is exactly axial to the Barrel cylinder is ground conically, and in an undivided sleeve with the same counter cone is recorded, so that a relative displacement between the spring band and the conical sleeve regulates the bearing diameter enables. The special feature of the novelty of this bearing is that the ends of the conical spring conveyor belt can be intercepted by means of two rotatable side discs and rotated against each other by the diameter of the treadmill and thereby the relative displacement between the treadmill

Hierbei sind diese Seitenscheiben in den Verlängerungen der Stellmuttern für die Verschiebung derKonushülse gelagert, so daß eine Veränderung der Lage der Arbeitsspindel zum Spindelkasten nicht eintreten kann. Außerdem wird das Fe-lerlaufband beim Festziehen der Stellir.uttern seitlich verspannt, um ein Wandern der einzelnen Windungen während des Laufens zu verhindern. Die Windungen des Laufbandes sind aber dicht aneinanderliegendso and the outer conical sleeve to allow regulation and securing of the Bearing diameter. These side washers are in the extensions of the adjusting nuts for moving the conical sleeve stored so that a change in the position of the work spindle to the headstock cannot occur. Besides, that will Fe-ler treadmill when tightening the adjusting nuts laterally braced to prevent the individual turns from migrating while running.

Das Laufband ist außerdem noch mit Vorspannungen gewickelt, d. h. für einen kleineren Durchmesser als der äußere Durchmesser über den Rollen gemessen, so daß das Band durch seine eigene Federkraft stets fest auf den Rollen aufliegt und das Einstellen in die äußere Konushülse begünstigt. .wound so that a lateral shift of individual courses does not take place can, or that, if a shift occurs, all gears are shifted at the same time have to. The treadmill is also wound with pretension, i.

In der Zeichnung ist ein solches Lager im Schnitt dargestellt, und zwar ist dasselbe hier in eine Arbeitsspindel einer Werkzeugmaschine eingebaut, bei welchem dasselbe vorzugsweise Verwendung finden soll.In the drawing, such a bearing is shown in section, and that is the same installed here in a work spindle of a machine tool, in which the same thing should preferably be used.
Auf der Arbeitsspindel 1 ist ein Innenlaufring 2 aufgesetzt, um den die Rollen 3 angeordnet sind. Die Rollen 3 werden durch ein mit Vorspannung gewickeltes Federband 4 auf den Innenring festgepreßt. Das Federband 4 ist außen konisch geschliffen und in einer Hülse 5 mit gleichem Gegenkonus gelagert. Die Hülse 5 ist im Lagerkörper 15 verschiebbar angeordnet und an ihren Enden mit zwei Muttern 6 und 7 zur seitlichen Verschiebung versehen. Um ein Verdrehen der Konushülse 5 dem Spindelstock 15 gegenüber zu verhindern, besitzt letzterer eine Nut 13. in welche ein in der Konushülse 5 festsitzender Stift 14 eingreift. Die Muttern 6 und 7 sind als Überwurfmuttern ausgebildet 6$ und nehmen in ihren Bohrungen die mit Schlüsselnuten versehenen Seiteuscheiben S und 9 auf. die sich den Muttern gegenüberAn inner race 2, around which the rollers 3 are arranged, is placed on the work spindle 1. The rollers 3 are pressed tightly onto the inner ring by a spring band 4 wound with pretension. The spring band 4 is ground conically on the outside and is mounted in a sleeve 5 with the same counter cone. The sleeve 5 is arranged displaceably in the bearing body 15 and is provided at its ends with two nuts 6 and 7 for lateral displacement. In order to prevent the conical sleeve 5 from rotating with respect to the headstock 15, the latter has a groove 13, into which a pin 14 that is fixed in the conical sleeve 5 engages. The nuts 6 and 7 are as union nuts 6 $ formed and be in their bores which are provided with keyways Seiteuscheiben S and 9. facing the nuts

leicht verdrehen lassen. Diese Seitenscheiben 8 und g besitzen seitliche Ansätze, auf die sich die Enden des Federbandes 4 auflegen, und dienen gleichzeitig zur seitlichen Führung der Rollen. Gegen das Eindringen von Schmutz in das Lager sind die Seitenscheiben mit Dichtungen 11 und 12 versehen; ferner bildet die vordere Seitenscheibe S mit der Spindelmutter 10 einen engen konischen Schlitz, der beim Umlaufen der Spindel 1 eine Saugwirkung nach außen hervorbringt, so daß kein Kühlwasser oder Späne in das Lager gelangen können.let it twist slightly. These side panels 8 and g have lateral lugs on which the ends of the spring band 4 rest, and at the same time serve to guide the rollers laterally. The side windows are provided with seals 11 and 12 to prevent dirt from penetrating the bearing; Furthermore, the front side disk S forms with the spindle nut 10 a narrow conical slot which, when the spindle 1 rotates, produces a suction effect to the outside, so that no cooling water or chips can get into the bearing.
Das Federband 4· wird durch \Terdrehung der Seitenscheiben 8 und 9 in Richtung der Federenden enger gewickelt sowie durch Verdrehen der Stellmuttern 6 und 7 die Hülse 5· dem Federband gegenüber verschoben und gleichzeitig das Federband 4 mit den Seitenscheiben 8 und 9 zusammen seitlich verspannt, so daß ein Wandern des Laufbandes während des Laufens gänzlich ausgeschlossen ist. Der Durchmesser des Federbandes wird somit durch die Hülse gesichert und das ganze Lager am Lagerkörper 15 festgezogen, ohne daß durch die Verstellung der Muttern eine Axialverschiebung der Spindel 1 eintreten kann.The spring strip 4 x is \ T erdrehung of the side plates 8 and tightly wound in the direction of the spring member 9, and by turning the adjusting nuts 6 and 7, the sleeve 5 · the spring band opposite shifted and simultaneously braces the spring tape 4 along the side with the side plates 8 and 9 so that the treadmill cannot wander while running. The diameter of the spring band is thus secured by the sleeve and the entire bearing is tightened on the bearing body 15 without the spindle 1 being able to move axially as a result of the adjustment of the nuts.
