Description

RollenlagerRoller bearings

Die Erfindung hat eine weitere Ausbildung des im Hauptpatent beschriebenen Rollenlagers, bei welchem die die Rollen im gegenseitigen Abstand haltenden Trennstücke derart ausgebildet sind, daß nach den Berührungsflächen zu keilförmige Schmiermittelräume vorhanden sind, zum Gegenstand. Die Zuführung des Schmiermittels zu den Berührungsflächen läßt sich erfindungsgemäß noch dadurch weiter vervollkommnen, daß man die Abstandstücke mit Nuten versieht. Zweckmäßig können diese Nuten so angebracht werden, daß sie nicht bis zu den eigentlichen Anlageflächen der Stege reichen und diese somit keine Unterbrechung erfahren. Bringt man ferner die Nuten auf beiden Seiten der Längsmittelebene der Stege versetzt zueinander an, so wird erreicht, daß jede Rolle während einer Umdrehung mit ein und demselben Punkt ihres Umfanges bei dem einen Abstandstück an den durch die Nuten gebildeten Zähnen, dagegen an dem benachbarten Abstandstück an der mit Fett gefüllten Zahnlücke vorbeigeht, somit jeder Punkt des Rollenumfanges während eines Umlaufes einmal mit dem Schmierstoff in Berührung gebracht wird.The invention has a further development of the roller bearing described in the main patent, in which the roles in the mutual Spacer separators are designed such that after the contact surfaces Too wedge-shaped lubricant spaces are available, to the subject. the According to the invention, the lubricant can be supplied to the contact surfaces further perfect by providing the spacers with grooves. Appropriate these grooves can be attached so that they do not extend to the actual contact surfaces of the webs and these thus experience no interruption. If you also bring the grooves on both sides of the The longitudinal center plane of the webs offset from one another, so that each role during one revolution with one and the same point of its circumference at the one Spacer on the teeth formed by the grooves, but on the adjacent one Spacer passes the grease-filled tooth gap, thus every point of the Roll circumference brought into contact with the lubricant once during one revolution will.

Auf der Zeichnung ist die Erfindung in einem Ausführungsbeispiel zur Darstellung gebracht. Es zeigtThe invention is shown in an exemplary embodiment in the drawing. It shows

Abb. ι ein mit solchen kammartigen Einfräsungen versehenes Trennstück in seiner Lage zwischen zwei Rollen, während Abb. 2 und 3 das Trennstück in Grundriß und Seitenansicht veranschaulicht.Fig. Ι a separating piece provided with such comb-like millings in its Position between two roles, while Fig. 2 and 3 the separator in plan and side view illustrated.

Das Abstandstück« ist auf seinen den Rollen b zugekehrten Flächen mit kammartigen Einfräsungen c und d versehen, welche nicht ganz bis zum schwächsten Teil.e der Abstandstücke, ,an der sich die Rollen und die Ab- 4c standstücke berühren, reichen. Die rechts von der Längsmittelebene der Stege liegenden Einfräsungen d sind um eine Zahnbreite gegenüber den links von der Mittelebene liegenden Einfräsungen c versetzt, wodurch nicht 4i nur, wie bereits erwähnt, eine erhöhte Gewähr für die Berührung eines jeden Punktes der Rolle mit dem Schmierstoff geboten wird, sondern auch dem Abstandstück ein günstigeres Widerstandsmoment erhalten bleibt. Der 5c Schmierstoff vermag infolge der kammartigen Einfräsungen der Stege in wesentlich ergiebigerem Maße zu den Anlageflächen von Rolle und Steg zu dringen, wobei ferner die Zahnlücken den zu schmierenden Flächen unmittel- 5£ bar vorgelagerte' Schmiermittelvorratsräume bilden, aus welchen den Rollen sofort beim Anlauf das Schmiermittel zugeführt wird.The spacer is provided on its surfaces facing the rollers b with comb-like millings c and d , which do not extend all the way to the weakest part. e of the spacers, where the rollers and the 4c spacers touch, are sufficient. The milled slots located to the right of the longitudinal center plane of the webs are d offset c is a tooth width in relation to the lying to the left of the center plane milled, thereby not 4i only, as already mentioned, offered an increased guarantee of the touch of any point of the roll with the lubricant , but also the spacer a more favorable section modulus is retained. As a result of the comb-like millings of the webs, the 5c lubricant is able to penetrate to the contact surfaces of the roller and web to a much more efficient extent, with the gaps in the teeth also forming lubricant storage spaces immediately in front of the surfaces to be lubricated, from which the rollers immediately upon start-up Lubricant is supplied.
