Description
Bei der Herstellung von Rollen für Rollenlager, die Ewischen Spitzen geschliffen oder ähnlich behandelt werden sollen, müssen die Rollen, damit sie während der Bearbeitung zwischen Spitzen gehalten werden können, mit Zentrierbohrungen versehen werden. Es hat sich nun bei der Herstellung derartiger Rollen, die gehärtet oder warm behandelt werden müssen, gezeigt, daß an den Zentrierbohrungen Risse entstehen, die sich nach dem Umfang zu ausdehnen. Diese Risse führen bei den Rollen für Rollenlager, die großen Drücken ausgesetzt sind, zur Zerstörung der Rolle und können oft die Rolle in zwei oder mehrere Teile spalten.In the manufacture of rollers for roller bearings, the Ewischen points are ground or Should be treated similarly, the roles must be so that they can be used during editing can be held between tips, are provided with centering holes. It has now proven itself in the manufacture of such roles that are hardened or hot treated must be shown that cracks occur in the centering holes, which after the To expand scope. These cracks result in the rollers for roller bearings, the large ones Pressures are exposed to the destruction of the reel and can often split the reel in two or more split several parts.
Die Erfindung bezweckt, die Rolle so auszubilden, daß die Rißbildung verhütet oder zumindest so weit beschränkt wird, daß ihre Zerstörung und- somit die Zerstörung des ao Lagers nicht eintreten kann.The invention aims to form the role so that the cracking prevents or is limited at least so far that their destruction and thus the destruction of the ao camp cannot occur.
Dies wird erreicht, wenn erfindungsgemäß die Rolle aus einem Kern und einer oder mehreren mechanisch fest zusammengefügten Mantelschichten besteht. Auf diese Weise kann ein Riß, der von der Zentrierbohrung ausgeht, sich nur bis zur Berührungsfläche des Kernes mit der nächsten Mantelschicht ausbreiten und nicht bis zur Oberfläche der Rolle durchgehen, so daß eine vollkommene Spaltung der Rolle unmöglich ist. Kern und Mantelschicht bzw. -schichten können aus verschiedenen Werkstoffen bestehen. Zweckmäßig wird der Kern weicher als die Mantelschichten ausgebildet. Vorteilhaft wird der Kern aus nicht härtbarem Material hergestellt, das das Anbringen von Zentrierbohrungen gestattet, nachdem die Mantelschichten gehärtet worden sind.This is achieved when according to the invention the role of a core and one or consists of several mechanically tightly joined shell layers. In this way a crack starting from the centering hole can only extend to the contact surface of the core with the next cladding layer and not to the surface of the Scroll through the role so that a complete split of the role is impossible. Core and The outer layer or layers can consist of various materials. Appropriate the core is made softer than the cladding layers. The core is advantageously made of non-hardenable material, that allows centering holes to be made after the cladding layers have been cured.
Der zur Herstellung der Rolle dienende Stab kann auf irgendeine geeignete Weise mit einem Kern versehen werden, z. B. durch Ausbohren des mittleren Mantels und Hineinführen einer Stange aus Kernmaterial, worauf die Stange auf die für die Herstellung der Rolle erforderliche Länge gebracht wird. Man kann auch das Kernmaterial in die Bohrungen gießen. Ebenso können die Mantelschichten um den Kern herumgegossen werden. Nach dem Ziehprozeß ist der Kern mit den umgebenden Mantelschichten genügend fest verschweißt. Für Stoffe, die nicht zusammenschweißen, kann der Kern auch nur durch die Reibung zwischen Kern und den umgebenden Mantelschichten gehalten werden. In diesen Fällen läßt sich die Reibung durch Anwendung eines Kernstoffes vergrößern, der sich bei Warmbehandlung stärker ausdehnt als der umgebende Stoff.The rod used to make the roll can be included in any suitable manner be provided with a core, e.g. B. by drilling out the middle shell and inserting it a rod of core material, after which the rod is brought to the length required for the manufacture of the roll. You can also pour the core material into the holes. Likewise, the cladding layers be poured around the core. After the drawing process, the core with the surrounding cladding layers is sufficient firmly welded. For materials that do not weld together, the core can only are held by the friction between the core and the surrounding cladding layers. In these cases the friction can be increased by using a core material, which expands more strongly than the surrounding fabric during heat treatment.
In der Zeichnung ist der Gegenstand der Erfindung beispielsweise dargestellt.In the drawing, the subject matter of the invention is shown for example.
Fig. ι zeigt eine Rolle für Rollenlager im Querschnitt, bei der der mit den Zentrier-Fig. Ι shows a role for roller bearings in cross section, in which the with the centering
bohrungen 3 versehene Kern 1 mit einer Mantelschicht 2 umgeben ist.bores 3 provided core 1 with a cladding layer 2 is surrounded.
Fig. 2 zeigt einen axialen Schnitt durch eine Rolle, bei der der Kern 1 von zwei Mantelschichten 2, 4 umgeben ist.FIG. 2 shows an axial section through a roller in which the core 1 is surrounded by two cladding layers 2, 4.
Fig. 3 zeigt die Rolle nach Fig. 2 in Vor-, deransicht.FIG. 3 shows the roller according to FIG. 2 in a front view.
Fig. 4 veranschaulicht ebenfalls in Vorderansicht eine Rolle, die aus einem Kern und zwei Manielschichten besteht. Der hier dargestellte Riß 5 erstreckt sich von der Zentrierbohrung 3 bis zum Berührungspunkt 6 zwischen dem Kern 1 und der ihn umgebenden Mantelschicht 2.Fig. 4 illustrates, also in front view, a roll consisting of a core and two maniel layers. The crack 5 shown here extends from the centering hole 3 to the point of contact 6 between the core 1 and the one surrounding it Coat layer 2.
