Wälzlagerroller bearing
Bei Wälzlagernj die sehr hohen Beanspruchungen ausgesetzt sind, wird innerhalb des lagers ein beachtlicher Teil von Reibungswärme erzeugt", "der- ein verhältnismäßig großes .Temperaturgefälle" zwischen-deia Innen- und dem Außenring herbeiführt» !Deshalb; ist es erforderlich, Wälzlager dieser Art mit einem sogenannten Iiagerspiel/deh„ einer Distanz zwischen den Rollen und deren laufbahn.auszurüsten, damit trotz der größeren Ausdehnung; des Innenringes keine.-Ve r spannung der Rollen zwischen dem Innen- und dem.Außenring entsteht.In the case of rolling bearings that are exposed to very high loads, a considerable amount of frictional heat is generated inside the bearing, "which causes a relatively large" temperature gradient "between the inner and outer rings! with a so-called Iiagerspiel / d e h "of a distance between the rollers and their laufbahn.auszurüsten so that in spite of the larger expansion, the inner ring keine.-r Ve voltage of the rollers between the inner and dem.Außenring formed.

Die aufgetretenen Schwierigkeiten sollen nach der -vorliegenden Erfindung in erster linie dadurch beseitigt .werden, daß zwischen den -Wälz-körpern- und deren am Außen- oder Innenring befindlichen la Uf bahnen ringförmige elastische Mittel angeordnet sind, die jeweils mit Hilfe einer Mut in eine der sich gegenüberstehenden Flächen eingreifen und einen ständigen Reibungss.ehluß der-Wälzkörper mit ihren laufflächen herstellen sollen. Somit ist es dann nicht mehr möglich, daß .die laufrollen durch .die Käflgreibung abgebremst werden, und der unangenehme Verschleiß wird vermieden.The difficulties encountered should according to the present Invention primarily be eliminated by this. that between the rolling bodies and their on the outer or inner ring located la Uf lanes annular elastic means are arranged, each with the help of a courage in a the opposing surfaces intervene and a constant Reibungss.ehluß of the rolling elements with their running surfaces should produce. This means that it is no longer possible for the rollers to be braked by cage friction, and the unpleasant wear and tear is avoided.
Ausführungsbeispiele des Erfindungsgegenstandes sind in den beigefügten Zeichnungen anschaulich dargestellt.Embodiments of the subject matter of the invention are in attached drawings clearly shown.
In Fig. 1 ist ein Zylinderrollenlager bekannter Bauart abgebildet, das im wesentlichen aus dem Außenring 1, den zylindrischen Wälzkörpern 2, dem Käfig 3 und dem Innenring 4 besteht. Wie es gewissen Wälzlagertypen entspricht, sind die Wälzkörper 2 oder der Innenring 4 leicht ballig bearbeitet, so daß ausschließlich die mittlere Zone belastet wird. Daher sind in den Außenzonen des Innenringes 4 luten angeordnet," "die"mit.ringförmigen, elastischen Mitteln 6, z.B. G-ummiringen, ausgelegt sind. Diese werden in derüberlasteten Zone Tollstandig--zusammengedrückt, wodurch sieh die Wälzkörper 2 an die laufbahn-dss Innenringes 4 anj^en können. In der entlasteten;Zone dehnen^sie sich dagegen aus und bleiben^*! ständiger Berührung mit den Wälzkörpern1 shows a cylindrical roller bearing of a known type, which essentially consists of the outer ring 1, the cylindrical rolling elements 2, the cage 3 and the inner ring 4. As it corresponds to certain types of rolling bearings, the rolling elements 2 or the inner ring 4 are machined slightly crowned, so that only the middle zone is loaded. Therefore, in the outer zones of the inner ring 4 lutes are arranged, "" which are designed with ring-shaped, elastic means 6, for example G-ummiringen. ds s inner ring 4 anj ^ can en In the unloaded;.! zone stretching them ^ against it and remain ^ * constant contact with the rolling elements
Unter diesenUmständen werden die Wälzkörper 2, zusätzlich zur normalen^^ FixehkraftlDeanspruGnung auch noch durch die elastischen Ringe 6 gegen die laufbahn:des Außenringes 1 gedrückt, so daß sie In der entlasteten Zone nicht abgebremst werden,können. /Under these circumstances, the rolling elements 2 are additionally to normal ^^ fixed eyesight strain also through the elastic rings 6 against the raceway: of the outer ring 1 pressed so that they are not braked in the relieved zone be, can. /
ü?ig« 2 ist einev andere Bau-form, eines mit der !Teuerung ausgerüsteten Zylinderrollenlagers zu entnehmen. Bei diesem Torschlag sind die Nuten 5 und die elastischen Hinge 6 an den Wälzkörpern2 angebracht. Der Innenring 4 erhält demnach keine Nuten und keine elastischen Ringe.ü? ig «2 is a different type of construction, one with the high price To be taken from the cylindrical roller bearing. In this gate strike, the grooves 5 and the elastic hinge 6 are on the Rolling elements2 attached. The inner ring 4 is accordingly given no grooves and no elastic rings.
Aus !Fig.- 3 ist die Anordnung der elastischen Ringe 6 am Wälzkörper 2 in vergrößertem Maßstab ersichtlich.From! Fig. 3 the arrangement of the elastic rings 6 on the Rolling bodies 2 can be seen on an enlarged scale.
Die Pig. 4 bis 6.zeigen einen Ausführungsvorschlag der Erfindung am Beispiel eines Zylinderrollenlagers, welches sich wiederum im wesentlichen aus dem Außenring 1, den Wälzkörpern 2, dem Käfig. 3 und dem Innenring 4 zusammensetzt. Dieser Innenring 4 besitzt gleichfalls zwei Nuten 5, die außermit einem elastischen Mittel 6 noch mit einem vorzugsweise aus lederstahl gefertigten Spreizring 7 versehen sind. !Letzterer dehnt slci so weft-a<us, bis er auf seinem gesamten Umfang den Reib ungs Schluß mit.^^ den tälzkörpern 2 hergestellt hat« In der belasteten Zone wird der Spreizring 7 dabei in das elastische Mittel 6 .eingedrückt. '^The Pig. 4 to 6 show a proposed embodiment of the invention using the example of a cylindrical roller bearing, which is again essentially from the outer ring 1, the rolling elements 2, the cage. 3 and the inner ring 4 composed. This Inner ring 4 also has two grooves 5, which also an elastic means 6 or preferably with one made of leather steel expansion ring 7 are provided. ! The latter stretches slci so weft-a <us until he is on his entire Scope of the frictional conclusion with. ^^ the tälzkkörern 2 made has «In the stressed zone, the expansion ring 7 is pressed into the elastic means 6.
