Bei dem in Fig. 1 bis 3 dargestellten Rollenlager wird nur eine halbe Lagerschale e mit Lagerdeckel b angewendet. Zwischen dem Zapfen α und der Lagerschale e laufen zwei aus Gliedern ο gebildete, die Rollen c tragende Ketten und treten unterhalb der Welle in die beiden Führungen η η, zwischen welchen die Rollen einen kleinen Spielraum haben. Auf dem Zapfen sind zwei den Ringnuthen c1 der Rollen entsprechende Spurkränze angeordnet, wodurch die Rollen Zwanglauf erhalten. Der Durchmesser der Rollen c ist gleich dem Halbmesser des Zapfens a, so dafs bei einer Umdrehung .zwei Rollen aus dem Lager aus- und zwei dafür wieder einlaufen, und da die Kette aus 30 Rollen besteht, macht die Rollenkette erst bei 15 maliger Umdrehung der Welle einen Umlauf. Die Abnutzung der Rollen fällt deshalb sehr gering aus, und da von allen Seiten frische Luft eintreten kann, kommt ein Warmlaufen des Zapfens nicht vor. Man kann durch Vermehrung der Rollen den Rollengang noch verlangsamen oder, wo dies nicht nöthig, weniger Rollen anbringen. Die Deckel y schützen den Rollengang gegen Einfallen von Staub u. dergl., während das Lager nach unten vollständig offen ist. Die Rollenführungen η η sind mittelst der Leisten rr und Bolzen h h mit einander verbunden und am Lager befestigt, wobei die Verbindung S S noch eine Verstärkung herstellt. Um die Rollengänge bei heftigem Stofs vor Beschädigung zu schützen, ist unter der Welle die Querschiene m angebracht und mit dem Lager verbunden. Um einen ruhigen Gang zu erzielen, kann man zwischen die Lagerschale e und den Lagerdeckel b eine Gummi-, Filz- oder dergleichen Unterlage einfügen.In the roller bearing shown in Fig. 1 to 3, only half a bearing shell e with bearing cover b is used. Between the pin α and the bearing shell e , two chains formed from links ο and carrying the rollers c run and enter the two guides η η below the shaft, between which the rollers have a small amount of play. Two flanges corresponding to the ring grooves c 1 of the rollers are arranged on the journal, whereby the rollers are forced to run. The diameter of the rollers c is the same as the radius of the pin a, so that with one revolution two rollers leave the bearing and two come in again, and since the chain consists of 30 rollers, the roller chain only makes 15 rotations of the Wave one round. The wear on the rollers is therefore very low, and since fresh air can enter from all sides, the pin does not warm up. By increasing the number of rollers, the roller conveyor can be slowed down or, where this is not necessary, fewer rollers can be fitted. The covers y protect the roller conveyor against the ingress of dust and the like, while the bearing is completely open at the bottom. The roller guides η η are connected to one another by means of the strips rr and bolts hh and fastened to the bearing, the connection SS also providing a reinforcement. In order to protect the roller conveyors from damage in the event of heavy material, the cross rail m is attached under the shaft and connected to the bearing. In order to achieve a smooth walk, a rubber, felt or similar pad can be inserted between the bearing shell e and the bearing cover b.

Eine Abänderung ist in Fig. 4 gezeichnet. Eine auf die Welle α gesteckte Hülse i, welche nach Bedarf vergröfsert oder verkleinert werden kann, nimmt zwischen sich und dem Lagerdeckel e die Rollen c auf, welche mit den Gliedern ο zu einer endlosen Kette verbunden sind, die nach unten frei hängt. Die unteren Rollenführungen kommen hier also in Wegfall, und es bleiben nur die oberen Führungen n. A modification is drawn in FIG. A sleeve i placed on the shaft α , which can be enlarged or reduced as required, takes the rollers c between itself and the bearing cover e , which are connected to the links ο to form an endless chain that hangs freely downwards. The lower roller guides are omitted here, and only the upper guides n remain.

Patent-Anspruch:Patent claim: Ein Rollenlager, bei welchem zum Zwecke der Vermeidung des Schmierens unter Wegfall einer Lagerschalenhälfte in Führungen η η zwangläufig gehende endlose Rollenketten c c verwendet werden, welche zwischen der bestehenden Lagerschalenhälfte und der Welle hindurchlaufen und der Luft freien Durchtritt gestatten.A roller bearing in which, in order to avoid lubrication, with the omission of a bearing shell half in guides η η, endless roller chains cc are used which run between the existing bearing shell half and the shaft and allow the air to pass freely.
