Description
KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Gegenstand der Erfindung ist ein Rollenlager mit Hohlrollen, die zwischen seitlichen Ringen gelagert sind. Bei Rollenlagern, die hauptsächlich zur Übertragung großer Kräfte in Frage kommen, ist von der Art der Rollenführung im wesentlichen die Güte des Lagers abhängig. Die Führung der Rollen hat zwei Anforderungen zu genügen. Sie muß das Ecken der Rollen verhindern und gleichzeitigThe invention relates to a roller bearing with hollow rollers between the lateral Rings are stored. For roller bearings that are mainly used to transmit large forces come into question, the type of roller guide is essentially the quality of the bearing addicted. The leadership of the roles has to meet two requirements. It must prevent the rolls from cornering and at the same time
ίο ein geringes Verschieben der Rollen in Richtung der zu übertragenden Kraft gestatten, damit der Druck nur durch die Rollen aufgenommen wird und die Führung selbst stets unbelastet bleibt.ίο a slight shifting of the rollers in the direction of allow the force to be transmitted so that the pressure is only absorbed by the rollers and the leadership itself always remains unencumbered.
Gegenüber den bekannten zwischen seitlichen Ringen gelagerten Hohlrollen besteht nun das Wesen der Erfindung darin, daß in die Hohlrollen zylindrische und mit einer über die ganze Länge sich erstreckenden Nut versehene Zwischenstücke eingelegt sind, in welche Querbalken von rechteckigem Querschnitt eingreifen, die an den Führungsringen befestigt sind.Compared to the known hollow rollers mounted between the side rings Now the essence of the invention is that in the hollow rollers cylindrical and with one over the entire length extending groove provided intermediate pieces are inserted into which Engage crossbars of rectangular cross-section, which are attached to the guide rings are.
Von dem Rollenlager zeigt Fig. ι einen Längsschnitt, und Fig. 2 den halben Querschnitt und die halbe Seitenansicht.FIG. 1 shows a longitudinal section of the roller bearing, and FIG. 2 shows half the cross section and the half side view.
Das Lager besteht aus den beiden konzentrischen Ringen α und b, von denen der eine mit dem drehenden, der andere mit dem feststehenden Teil verbunden werden kann.The bearing consists of the two concentric rings α and b, one of which can be connected to the rotating part and the other to the stationary part.
Zwischen den Ringen α und b sind die Rollen c gelagert, die der ganzen Länge nach konzentrisch zylindrisch ausgebohrt sind.Between the rings α and b , the rollers c are mounted, which are bored concentrically and cylindrically along their entire length.
In den Rollen c befindet sich das zylindrische Zwischenstück d, welches auf seiner ganzen Länge eine rechteckige Nut besitzt.In the rollers c there is the cylindrical intermediate piece d, which has a rectangular groove along its entire length.
In diese greift der Querbalken e ein, ohne die Nut nach oben und unten völlig auszufüllen. The crossbar e engages in this without completely filling the groove up and down.
Derselbe besteht aus einem rechteckigen, mittleren Teil, der an seinen beiden Enden in zwei kreisförmige Zapfen ausläuft, durch die der Querbalken mit den beiden Führungsringen f fest verbunden werden kann.The same consists of a rectangular, central part, which terminates at both ends in two circular pins, through which the crossbar can be firmly connected to the two guide rings f.
Durch diese Anordnung wird erreicht, daß die Hohlrollen c einmal mit Hilfe des Zwischenstückes d und des Querbalkens β ihrer ganzen Länge nach geführt sind, so daß ein Ecken ausgeschlossen ist, und daß sich dieselben in Richtung der zu übertragenden Kraft, d. h. im vorliegenden Falle in radialer Richtung, in geringem Maße verschieben lassen, wodurch die Führung f selbst stets unbelastet bleibt.By this arrangement it is achieved that the hollow rollers c once with the help of the intermediate piece d and the crossbar β are guided along their entire length, so that corners are excluded, and that the same in the direction of the force to be transmitted, ie in the present case in radial direction, can be shifted to a small extent, whereby the guide f itself always remains unloaded.
