Abstract
Description
Die Erfindung betrifft einen Käfig nach dem Oberbe griff des Anspruchs 1.The invention relates to a cage according to the Oberbe handle of claim 1.
Aus der DE 35 40 224 C2 ist ein Käfig für ein zweirei higes Kugellager bekannt, bei dem über am Käfig ange brachte Haltenasen eine Baueinheit erzielt wird. Nach teilig bei einem solchen Käfig ist, daß bei unter schiedlichen Abrollverhältnissen unter den jeweiligen Kugelreihen Zwangskräfte vom Käfig aufgenommen werden müssen, die ihn zusätzlich beanspruchen oder die Ab rollverhältnisse der anderen Kugelreihen beeinflussen.DE 35 40 224 C2 describes a cage for a double row higes known ball bearings, in which on the cage brought retaining lugs a unit is achieved. After part of such a cage is that under different rolling conditions under the respective Ball rows of constraining forces are absorbed by the cage who claim it additionally or the Ab influence the rolling ratios of the other rows of balls.
Um diesen Nachteil zu vermeiden, ist es aus der DE 40 37 270 A1 bekannt, bei einem zweireihigen Schrägwälz lager für jede Rollkörperreihe einen eigenen Käfig vorzusehen, der mit schräg geneigten Ringteilen verse hen ist, welche die reziprok gestalteten Ringteile des gegenüberstehenden Käfigs hintergreifen. Damit läßt sich eine Baueinheit erzielen. Auch ein Vor- oder Nachlaufen der Rollkörperreihen gegeneinander in Um fangsrichtung wird ermöglicht. Nachteilig dabei ist, daß zwei Käfigausführungen je Lager benötigt werden und bis zum Zusammenbau des Lagers zwei Rollkörper sätze vorhanden sind, die das Handling erschweren.To avoid this disadvantage, it is from DE 40 37 270 A1 known, with a double row helical roller bearings for each row of rolling elements to provide the verse with obliquely inclined ring parts hen, which is the reciprocally designed ring parts of the reach behind the opposite cage. So that leaves achieve a structural unit. Also a pre or Tracking the rows of rolling elements against each other in um catch direction is made possible. The disadvantage is that two cage designs are required per bearing and two rolling elements until the bearing is assembled sets are available that make handling more difficult.
Es ist deshalb Aufgabe der Erfindung, einen Käfig der eingangs genannten Art so weiterzubilden, daß er die genannten Nachteile nicht mehr aufweist und sowohl ein einfaches Handling ermöglicht, als auch ein zwangs kräftefreies Abrollen der Rollkörper erlaubt. It is therefore an object of the invention to provide a cage type mentioned so that he the no longer has the disadvantages mentioned and both a easy handling allows, as well as a forced force-free rolling of the rolling elements allowed.
Die Lösung dieser Aufgabe gelingt mit den im kenn zeichnenden Teil des Anspruchs 1 angegebenen Merkmalen.This task can be solved with the im Drawing part of claim 1 specified features.
Aus der DE 31 39 932 A1 oder der EP 0 241 879 B1 ist zwar ein Käfig mit einer Sollbruchstelle bekannt, zur Lösung der vorliegenden Aufgabe ist dieser aber nicht geeignet.From DE 31 39 932 A1 or EP 0 241 879 B1 a cage with a predetermined breaking point is known for However, this is not the solution to the present problem suitable.
Die Erfindung soll an einem Ausführungsbeispiel näher erläutert werden.The invention is to be closer to an embodiment are explained.
Fig. 1 zeigt ein zweireihiges Schrägkugellager mit einem erfindungsgemäßen Käfig im Teilquerschnitt. Der Einteilige Außenring ist mit 1 bezeichnet. Er hat zwei Laufbahnen für die Kugeln 2, die in zwei Reihen ange ordnet sind und von einem Käfig 3 auf Abstand gehalten werden. Um eine Baueinheit zu erreichen, ist in diesem Fall der Käfig 3 mit einer Haltenase 4 versehen, die in eine Nut 5′ des zweiteilig ausgebildeten Innenrings 5 eingreift. Der andere Innenring 6 hat eine leicht überhöhte Schulter 6′, so daß über den Käfig 3, dessen Taschen die Kugeln teilweise umgreifen, ein Zusammen halt der Lagerteile gegeben ist. Erfindungsgemäß ist der Käfig 3 zwischen den Wälzkörperreihen mit einer in Umfangsrichtung verlaufenden Sollbruchstelle 7 verse hen. Dadurch lassen sich bis zum Zusammenbau des Lagers die in die Käfigtaschen eingesetzten Kugeln 2 zu sammen mit dem Käfig als ein Teil handhaben, nach dem Zusammenbau des Lagers aber kann durch Trennen an der Sollbruchstelle sichergestellt werden, daß im Betrieb des Lagers auftretende unterschiedliche Abrollverhält nisse unter den Kugelreihen keine Zwangskräfte auf die jeweils andere Kugelreihe ausüben. Ein Vor- oder Nach laufen der Kugelreihen in Umfangsrichtung wird so mög lich. Es ist in manchen Anwendungsfällen ebenso denk bar, den Käfig zunächst nicht zu trennen. Wenn im Be trieb dann die Zwangskräfte eine vorbestimmte Höhe überschreiten, wird die Trennung an der Sollbruchstelle von selbst erfolgen und somit eine Schädigung des Lagers vermieden. Dabei kann die erfolgte Trennung an der Sollbruchstelle auch als Nachweis dienen, daß das Lager zu hohen Belastungen ausgesetzt war. Fig. 1 shows a double row angular contact ball bearing with a cage according to the invention in partial cross section. The one-piece outer ring is designated by 1 . It has two raceways for the balls 2 , which are arranged in two rows and are kept at a distance from a cage 3 . In order to achieve a structural unit, in this case the cage 3 is provided with a retaining lug 4 which engages in a groove 5 'of the two-part inner ring 5 . The other inner ring 6 has a slightly inflated shoulder 6 ', so that over the cage 3 , the pockets of which partially encompass the balls, there is a holding together of the bearing parts. According to the cage 3 hen between the rows of rolling elements with a circumferential predetermined breaking point 7 verses hen. Characterized the bearing can be to be together in the cage pockets used balls 2 with the cage handle as a part, but after the assembly of the bearing can be ensured by separating of the predetermined breaking point that nep occurring different Abrollverhält during operation of the bearing under to the assembly do not exert any constraining forces on the other row of balls. A before or after running the rows of balls in the circumferential direction is possible. In some applications it is also conceivable not to separate the cage initially. If in operation then the constraining forces exceed a predetermined level, the separation will take place automatically at the predetermined breaking point and thus damage to the bearing is avoided. The separation at the predetermined breaking point can also serve as proof that the bearing was exposed to high loads.
Natürlich ist die Erfindung auch bei mehrreihigen Rollen lagern sowohl radialer als auch axialer Bauart an wendbar.Of course, the invention is also in multi-row roles store both radial and axial design reversible.
