Description
Gebiet der ErfindungField of the invention
Die Erfindung betrifft ein Spannlager, welches im Wesentlichen aus einem verlängerten Innenring, der auf einer Welle gehalten ist, sowie aus einem Außenring und aus auf zugehörigen Laufbahnen abrollenden Wälzkörpern besteht.The The invention relates to a radial bearing, which consists essentially of a extended Inner ring, which is held on a shaft, as well as an outer ring and out on related Runways rolling rolling elements consists.
Hintergrund der ErfindungBackground of the invention
Ein derartiges Spannlager ist aus dem Fachbuch M. Albert/H. Köttritsch „Wälzlager – Theorie und Praxis”, Springer-Verlag Wien, New York, 1987 vorbekannt. Das auf Seite 24 dargestellt Spannlager ist dabei als Rillenkugellager ausgebildet, das einen verlängerten Innenring besitzt, der mit einem Exzenterring oder mit zwei Gewindestiften auf einer Welle befestigt ist. Die Mantelfläche des Außenringes ist in der Regel kugelig geschliffen, so dass sich der Außenring in einem entsprechend ausgebildeten Gehäuse einstellen kann, wenn die Lagerstellen nicht fluchten. Derartige Spannlager werden vorzugsweise für einfache Lagerungen verwendet und eigenen sich hauptsächlich zur Lagerung kurzer Wellen für Einbaustellen, an denen nur geringe Wärmedehnungen zu erwarten sind. Sie sind deshalb vor allem in Landmaschinen, Förderanlagen, Baumaschinen oder in anderen Apparaten zu finden und werden dort fast ausschließlich als Festlager benutzt.One Such insert bearing is from the textbook M. Albert / H. Köttritsch "Rolling bearings - Theory and practice ", Springer-Verlag Vienna, New York, 1987 previously known. The on page 24 illustrated radial bearing is designed as a deep groove ball bearing, the one extended Inner ring has, with an eccentric ring or two setscrews attached to a shaft. The outer surface of the outer ring is usually Ground spherical, so that the outer ring in a corresponding trained housing can adjust if the bearings are not aligned. such Spherical bearings are preferred for simple bearings are used and are mainly for Storage of short waves for Installation sites where only low thermal expansions are to be expected. They are therefore mainly in agricultural machinery, conveyor systems, construction machinery or found in other apparatus and are there almost exclusively as Fixed storage used.
Als nachteilig bei solchen Spannlagern hat es sich jedoch erwiesen, dass die Lagerringe in aufwändiger Weise spangebend aus Stahl gefertigt werden und dass zu deren Fixierung an einer Welle ein zusätzlicher Exzenterring oder eine zusätzliche Gewindebohrung zu fertigen ist. Dadurch entsteht für solche Spannlager ein hoher Fertigungsaufwand, der letztlich für relativ hohe Herstellungskosten ursächlich ist.When disadvantageous in such tension bearings, it has proved, however, that the bearing rings in consuming They are machined from steel and used for their fixation on a wave an additional Eccentric ring or an additional Threaded hole to manufacture. This creates for such Spherical bearing a high production cost, which ultimately for relative high production costs cause is.
Durch
die
Auch für dieses Spannlager ist jedoch der Fertigungsaufwand nicht wesentlich geringer als bei dem zuvor beschriebenen Spannlager, da zumindest der äußere Lagerring nach wie vor in aufwändiger Weise spangebend aus Stahl gefertigt werden muss und somit die Herstellungskosten des Lagers erhöht. Da außerdem die Mantelfläche des Außenringes nicht kugelig ausgebildet ist und sich somit der Außenring auch nicht selbsttätig in einem entsprechenden Gehäuse einstellen kann, ist ein solches Spannlager ungeeignet für in Einbaulage nicht fluchtende Lagerstellen.Also for this Spherical bearing, however, the production cost is not significantly lower as in the previously described radial bearing, since at least the outer bearing ring still in a complex manner machined from steel and thus the production costs of the warehouse increased. There Furthermore the lateral surface the outer ring is not is spherical and thus the outer ring not automatically in one corresponding housing can adjust, such a radial bearing is unsuitable for in installation position non-aligned bearings.
Aufgabe der ErfindungObject of the invention
Ausgehend von den dargelegten Nachteilen der Lösungen des bekannten Standes der Technik liegt der Erfindung deshalb die Aufgabe zu Grunde, ein Spannlager zu konzipieren, das sich mit einem geringen Fertigungsaufwand und damit kostengünstig herstellen lässt und für nicht fluchtende Lagerstellen geeignet ist.outgoing from the stated disadvantages of the solutions of the prior art the technique is therefore the object of the invention, a radial bearing to design that with a low production cost and thus cost-effective can be produced and for non-aligned bearings is suitable.
Zusammenfassung der ErfindungSummary of the invention
Erfindungsgemäß wird diese Aufgabe bei einem Spannlager nach dem Oberbegriff des Anspruchs 1 dadurch gelöst, dass der Außenring eine kugelige Außenmantelfläche aufweist und dadurch in einem Gehäuse einstellbar ist und dass die Laufbahnen der Lagernadeln durch jeweils zwei spanlos hergestellte und einem Härteprozess unterworfene Laufscheiben zweier einander entgegen gerichteter Axialschrägnadellager gebildet werden, weiche über zwei zwischen den beiden Flanschen des Innenrings angeordnete und aus einem Nichteisenmetall bestehende Adapterringe im Innenring gehalten sind.According to the invention this Task at a radial bearing according to the preamble of the claim 1 solved by that the outer ring has a spherical outer surface and thereby in a housing is adjustable and that the raceways of the bearing needles by respectively two non-cutting produced and subjected to a hardening process pulleys two oppositely directed axial angular needle bearings are formed, soft over two arranged between the two flanges of the inner ring and made of a non-ferrous metal adapter rings in the inner ring are held.
Durch diese erfindungsgemäße Ausgestaltung des Spannlagers ist sichergestellt, dass es auch für nicht fluchtende Lagerstellen geeignet ist, wobei die spanlose Fertigung sämtlicher Einzelbestandteile der gesamten Lageranordnung gleichzeitig deren Herstellung in unterschiedlichen Dimensionen ohne Schwierigkeiten machbar ist. Auf diese Weise wird der Gesamtprozess der Lagerherstellung wesentlich vereinfacht und die Herstellungskosten erheblich verringert.By this embodiment of the invention The tension bearing ensures that it does not work aligned bearing points is suitable, the non-cutting production all Individual components of the entire bearing assembly simultaneously their production in different dimensions without difficulty is feasible. In this way, the overall process of bearing production is greatly simplified and significantly reduces the manufacturing costs.
Bevorzugte Ausgestaltungen und vorteilhafte Weiterbildungen des erfindungsgemäßen Spannlagers werden in den Unteransprüchen 2 bis 6 beschrieben.preferred Embodiments and advantageous developments of the clamping bearing according to the invention are in the subclaims 2 to 6 described.
So geht aus Anspruch 2 hervor, dass eine durch das Zentrum der Lagernadeln gelegte, unter einem Winkel von 90° zu deren Rotationsachse verlaufende, in Richtung Lagerachse weisende Mittelsenkrechte diese unter einem Winkel im Bereich von 15 bis 45° schneidet. Nach einem weiteren Merkmal gemäß Anspruch 3 soll der Innenring als ein Spanlosteil gefertigt sein. Gemäß Anspruch 4 sollen auch der Außenring und die Adapterringe als Spanlosteile gefertigt sein. Nach Anspruch 5 können der Außenring und die Adapterringe auch aus Aluminium bzw. aus einer Aluminiumlegierung gefertigt sein. Schließlich ist nach Anspruch 6 noch vorgesehen, dass das Spannlager in einem Gehäuse aus Grauguss, Stahl oder aus Kunststoff aufgenommen ist.Thus, it is apparent from claim 2, that a laid through the center of the bearing needles, running at an angle of 90 ° to the axis of rotation, pointing in the direction of the bearing axis bisector cuts them at an angle in the range of 15 to 45 °. According to a further feature according to claim 3, the inner ring should be made as a Spanlosteil. In accordance with claim 4, the outer ring and the adapter rings ge as Spanlosteile should be manufactures. According to claim 5, the outer ring and the adapter rings can also be made of aluminum or of an aluminum alloy. Finally, according to claim 6 is still provided that the radial bearing is housed in a housing made of gray cast iron, steel or plastic.
