Description

Bei Lagern für rotierende Maschinen ist man bestrebt, eine möglichst hohe Schmierfrist ohne Nachschmierung des Lagers zu erhalten. Dies stößt besonders bei Wälzlagern auf Schwierigkeit«, und ließ sich bisher nur dadurch lösen, daß man die Innen- und Außenringe des Lagers verbreitert. Eine solche Verbreiterung bedeutet aber einmal eine wesentliche Kostensteigerung und läßt eich andererseits aus räumlichen Gründen nicht überall durchführen. When it comes to bearings for rotating machines, efforts are made to achieve a to obtain long lubrication intervals without relubrication of the bearing. This is particularly difficult with roller bearings «, and so far could only be solved by widening the inner and outer rings of the bearing. Such a broadening but on the one hand means a significant increase in costs and, on the other hand, cannot be carried out everywhere for spatial reasons.

Die Neuerung löst das Problem auf.; „iifdche Weise dadurch, daß bei einem Wälzlager wenigstens juf einer Seite der Wälzkörper ein zusätzlicher Schmierstoffraum vorgesehen ist. Zweckmäßig wird zur Bildung des zusätslicher. Schnierstoffraume3 wenigstens eine der seitlichen Abdeck- oder Dichtscheiben als axial über das Lager hervorstehender, zu den Wälzkörpern hin offener hohler Ringwulst ausgebildet. In diesem Ringwulst läßt sich ein zusätzlicher Schmierstoffvorrat unterbringen, wodurch "1Le Sc^^* t ohne Nachschmierung wesentlich erhöht wird.The innovation solves the problem .; In this way, in the case of a roller bearing, an additional lubricant space is provided on at least one side of the roller bodies. It is useful to form the additional. Schnierstoffraume3 at least one of the lateral cover or sealing disks is designed as a hollow annular bead that protrudes axially beyond the bearing and is open towards the rolling elements. An additional supply of lubricant can be accommodated in this annular bead, which significantly increases "1 Le Sc ^^ * t without relubrication.

Die Zeichnung zeigt einige Ausf iihrungsbe-« xeie eines neuerungsgemäßen Wälzlagers.The drawing shows some implementation examples of an innovation according to the invention Rolling bearing.

In Pig. 1 bezeichnen 1 den Außenring, 2 den Innenring und 3 die Kugeln eines Kugellagers. Der Schmierstoffraum 4 zu beiden Seiten der Kugeln 3 ist in bekannter Weise seitlich durch Scheiben.5 abgedeckt, die am äußeren Ring 1 befestigt sind.In Pig. 1 denotes 1 the outer ring, 2 the inner ring and 3 the Balls of a ball bearing. The lubricant space 4 on both sides of the balls 3 is laterally covered by disks. which are attached to the outer ring 1.

Gemäß der Neuerung ist nun die linke Abdeckscheibe 6 so ausgebildet, daß sie einen Ringwulst mit einem Hohlraum 7 bildet. Dieser Hohlraum 7 ist nach den Kugeln hin offen und läßt sich mit einem Schmierstoffvorrat füllen.According to the innovation, the left cover 6 is now designed so that that it forms an annular bead with a cavity 7. This cavity 7 is open towards the balls and can be fill with a supply of lubricant.

Die Ausführungsbeispiele nach den Fig. 2 und 3 zeigen im Prinzip gleiche Lager, wobei ieuigiiuii die Audcckäohcibcu als Sichtscheiben ausgebildet sind. Zusätzlich sind hier im Schmierstoffraum 7 noch Stege 8 vorgesehen, die ein Kitumlaufen des im Raum 7 vorgesehenen Schmierstoffvorrates verhindern.The embodiments according to FIGS. 2 and 3 show in principle the same bearings, with the Audcckäohcibcu ieuigiiuii as viewing panes are trained. There are also in the lubricant room 7 webs 8 are also provided, which prevent the lubricant supply provided in space 7 from running around.
