Description
Gebiet der ErfindungField of the invention
Die Erfindung betrifft ein zweireihiges Schrägkugellager, mit einem Außenring, einem zweiteiligen Innenring und dazwischen in zwei Reihen angeordneten Kugeln.The invention relates to a double-row angular contact ball bearing, with an outer ring, a two-part inner ring and balls arranged therebetween in two rows.
Hintergrund der ErfindungBackground of the invention
Zweireihige Schrägkugellager sind für die Aufnahme kombinierter radialer und axialer Belastungen vorgesehen. Sie weisen zumeist einen massiven Außenring und einen massiven Innenring auf, die spanend als Drehteile hergestellt werden. Die Produktion derartiger herkömmlicher Schrägkugellager ist daher vergleichsweise aufwendig.Double row angular contact ball bearings are designed to accommodate combined radial and axial loads. They usually have a massive outer ring and a solid inner ring, which are produced by machining as turned parts. The production of such conventional angular contact ball bearings is therefore relatively expensive.
Aufgabe der ErfindungObject of the invention
Der Erfindung liegt die Aufgabe zugrunde, ein zweireihiges Schrägkugellager anzugeben, das einfacher hergestellt werden kann.The invention has for its object to provide a double-row angular contact ball bearings, which can be made easier.
Beschreibung der ErfindungDescription of the invention
Zur Lösung dieser Aufgabe ist bei einem zweireihigen Schrägkugellager der eingangs genannten Art erfindungsgemäß vorgesehen, dass der Außenring und der Innenring als Stanzziehteile hergestellt sind.To solve this problem, it is provided according to the invention in a double-row angular contact ball bearing of the type mentioned that the outer ring and the inner ring are made as stamped drawing parts.
Die Erfindung beruht auf der Erkenntnis, dass eine einfachere und kostengünstigere Herstellung eines Schrägkugellagers möglich ist, indem die üblicherweise spanend hergestellten Außen- und Innenringe durch Stanzen und Tiefziehen hergestellt werden. Auf diese Weise ergeben sich sowohl Vorteile hinsichtlich der Produktionszeit als auch hinsichtlich der Produktionskosten. Andererseits kann das erfindungsgemäße Schrägkugellager so dimensioniert werden, dass es dieselben Lasten wie ein herkömmliches zweireihiges Schrägkugellager aufnehmen kann.The invention is based on the finding that a simpler and more cost-effective production of angular contact ball bearings is possible by the usually machined outer and inner rings are produced by stamping and deep drawing. In this way, there are both advantages in terms of production time and in terms of production costs. On the other hand, the angular contact ball bearing according to the invention can be dimensioned so that it can accommodate the same loads as a conventional double-row angular contact ball bearings.
Gemäß einer ersten Ausgestaltung des erfindungsgemäßen Schrägkugellagers kann der Außenring aus einem Rohrabschnitt oder aus einer tiefgezogenen Zylinderhülse hergestellt sein. Dementsprechend kann ein Rohling durch Ablängen eines passenden Rohres hergestellt werden, dieser als Rohrabschnitt ausgebildete Rohling wird anschließend verformt, so dass auf der Innenseite die Laufbahnen für die Kugeln erzeugt werden.According to a first embodiment of the angular contact ball bearing according to the invention, the outer ring may be made of a pipe section or of a deep-drawn cylinder sleeve. Accordingly, a blank can be produced by cutting a suitable pipe to length, this blank formed as a pipe section is then deformed, so that on the inside of the raceways for the balls are generated.
Vorzugsweise weist der Außenring durch Rollieren hergestellte Laufbahnen auf. Beim Rollieren wird ein sich drehender Rohrabschnitt oder eine tiefgezogene Zylinderhülse mit großer Kraft gegen ein Rollierwerkzeug gedrückt, wodurch die gewünschte Kontur des Außenrings entsteht. Es liegt auch im Rahmen der Erfindung, dass beide Teile des geteilten Innenrings des Schrägkugellagers jeweils einen Falzabschnitt aufweisen. Dieser Falzabschnitt wird durch Umformen erzeugt und ermöglicht an der Außenseite des Innenrings das Ausbilden von Laufbahnen für die Kugeln.Preferably, the outer ring on raceways produced by rolling. When rolling a rotating pipe section or a deep-drawn cylinder sleeve is pressed with great force against a roller burnishing tool, whereby the desired contour of the outer ring is formed. It is also within the scope of the invention that both parts of the split inner ring of the angular contact ball bearing each have a folded portion. This folding section is produced by forming and allows on the outer side of the inner ring forming raceways for the balls.
Um eine lange Lebensdauer sicherzustellen, können zwischen dem Innenring und dem Außenring Dichtungen angeordnet sein. Alternativ oder zusätzlich können die Dichtungen mit einer Fettfüllung versehen sein. Zur Erhöhung der Dichtheit können die beiden Teile des geteilten Innenrings optional durch einen Haltering miteinander verbunden sein. Der Haltering greift in entsprechende Nuten ein, die beiderseits der Trennebene des geteilten Innenrings gebildet sind und dichtet diesen Bereich ab.In order to ensure a long service life, seals may be arranged between the inner ring and the outer ring. Alternatively or additionally, the seals may be provided with a grease filling. To increase the tightness, the two parts of the split inner ring can optionally be connected to each other by a retaining ring. The retaining ring engages in corresponding grooves which are formed on both sides of the parting plane of the split inner ring and seals this area.
Daneben betrifft die Erfindung ein Verfahren zur Herstellung eines zweireihigen Schrägkugellagers mit einem Außenring, einem zweiteiligen Innenring und dazwischen in zwei Reihen angeordneten Kugeln. Bei dem erfindungsgemäßen Verfahren ist vorgesehen, dass der Außenring und der Innenring durch Stanzen und Tiefziehen hergestellt werden.In addition, the invention relates to a method for producing a double-row angular contact ball bearing with an outer ring, a two-part inner ring and balls arranged therebetween in two rows. In the method according to the invention it is provided that the outer ring and the inner ring are produced by stamping and deep drawing.
In den Unteransprüchen sind weitere Ausgestaltungen der Erfindung beschrieben.In the subclaims further embodiments of the invention are described.
