Abstract

The one-piece double comb cage (4) for two-row ball bearings (2, 3) consists of a ring (6) between the rows of balls (2, 3). Both sides of the ring (6) have bridge-pieces (7) on them extending between the balls. The ring part (6) consists of connecting sections (6') forming a saw-tooth shape seen radially. The tips (6") of the teeth have the bridge pieces (7) formed on them. The connecting sections (6') have slanting or tradiallypointing holder-lugs fitting into grooves in the divided ball race. USE/ADVANTAGE - The ball bearing case is elastic in a circumferential direction.

Description

Die Erfindung bezieht sich auf einen einteiligen Doppelkammkäfig für zweireihige Kugellager nach dem Oberbegriff des Anspruchs 1.The invention relates to a one-piece Double comb cage for double row ball bearings according to the Preamble of claim 1.

Käfige der angegebenen Art werden in der DE-OS 26 56 823, DE-OS 36 43 533 und FR-PS 21 38 283 ge­ zeigt. Die hierin angegebenen Käfige besitzen alle den Nachteil, daß sie im Bereich des mittleren Ringteils nicht elastisch sind, selbst wenn der Käfig aus Kunststoff besteht. Eine Elastizität ist dann sehr wichtig, wenn das Lager sowohl Axial- als auch Radialkräfte übertragen soll. Dadurch verkippen die Laufringe geringfügig gegeneinander und die Kugeln laufen nicht auf dem gleichen Laufbahndurch­ messer ab, sondern steigen beispielsweise im weniger belasteten Bereich auf einen anderen Laufbahndurch­ messer. Dadurch kann ein "Vor- oder Nachlaufen" bestimmter Kugeln erfolgen. Die Kugeln laufen dann unterschiedlich an den Stegen des Käfigs an. Dies führt zu erhöhter Reibung und kann auch Stegbrüche nach sich ziehen. Außerdem ist das Profil spritz­ gießtechnisch sehr ungünstig, weil die Käfigab­ schnitte stark abweichende Querschnitte besitzen, was zu fehlerhaften Käfigen führen kann.Cages of the specified type are in DE-OS 26 56 823, DE-OS 36 43 533 and FR-PS 21 38 283 ge shows. The cages given here all have the disadvantage that they are in the middle Ring part are not elastic, even if the Cage made of plastic. There is an elasticity very important if the bearing is both axial and should also transmit radial forces. This will tilt it the races slightly against each other and the Bullets do not run on the same track knife, but increase less area to another raceway knife. This can lead to a "pre or post run" certain balls. The balls then run different on the webs of the cage. This leads to increased friction and can also break webs entail. The profile is also spritz casting technology very unfavorable, because the cage cuts have very different cross-sections, which can lead to faulty cages.

Es ist daher Aufgabe der Erfindung, den Käfig nach dem Oberbegriff des Anspruchs 1 so weiter zu ver­ bessern, daß die genannten Nachteile nicht auftreten und sich ein einfach und fehlerfrei herstellbarer Kammkäfig ergibt, der in Umfangsrichtung elastisch ist. It is therefore an object of the invention to the cage the preamble of claim 1 so on ver improve that the disadvantages mentioned do not occur and a simple and error-free to manufacture Comb cage results, which is elastic in the circumferential direction.  

Die Lösung dieser Aufgabe ist im kennzeichnenden Teil des Anspruchs 1 angegeben. Die Ansprüche 2 und 3 enthalten spezielle Ausgestaltungen.The solution to this problem is in the characteristic Part of claim 1 specified. Claims 2 and 3 contain special configurations.

Dadurch, daß die Verbindungsabschnitte des Ringteils in der radialen Draufsicht eine sägezahnähnliche Form bilden, ergibt sich kein vollvolumig umlaufen­ der Ringabschnitt mehr, sondern eine ziehharmonika­ ähnliche Ausführung. Diese ist sehr elastisch und ermöglicht das problemlose Vor- oder Nachlaufen von Kugeln, ohne daß dabei die Stege abbrechen, die an den jeweiligen Spitzen der Zähne angeformt sind.The fact that the connecting portions of the ring part in the radial top view a sawtooth-like Form, there is no full circulation the ring section more, but an accordion similar design. This is very elastic and enables the problem-free advance or follow-up of Bullets without breaking off the webs, the the respective tips of the teeth are molded.

Diese Käfigausführung hat noch den Vorteil, daß sie spritzgießtechnisch durch axial entfernbare Formtei­ le leicht herstellbar ist. Außerdem werden Material­ anhäufungen vermieden. Weiterhin ergeben sich noch zusätzlich Fetträume in den sägezahnähnlichen Frei­ räumen.This cage design has the advantage that it Injection molding through axially removable molded part le is easy to manufacture. Also, material accumulations avoided. Still arise additional fat spaces in the sawtooth-like free vacate.

Damit sich zumindest einseitig eine Axialfixierung zwischen der einen Kugelreihen und dem Käfig ergibt, besitzt eine Kugelreihe Stege mit die Kugeln hinter­ greifende Abschnitte. Dadurch wird eine axiale Verbindung hergestellt. Wenn man im Bereich der anderen Kugelreihe die hintergreifenden Abschnitte wegläßt, wird die Montage wesentlich erleichtert. Da bei einem zweigeteilten Laufring in diesem Fall aber keine Baueinheit entsteht, ist es nach einer weite­ ren Ausgestaltung zweckmäßig die Verbindungsab­ schnitte mit etwa radial gerichteten, am Umfang verteilten Haltenasen zu versehen, die in Nuten der geteilten Laufringe eingreifen. Wenn letztere schräg gerichtet sind, ist eine leichte Montage möglich. So that there is axial fixation at least on one side between one row of balls and the cage, has a row of balls with the balls behind gripping sections. This creates an axial Connected. If you are in the field of other row of balls the rear engaging sections omits, the assembly is much easier. There with a two-part race in this case no structural unit arises, it is after a distance Ren design expedient the connection cuts with approximately radial, on the circumference distributed retaining lugs to be provided in the grooves of the engage split races. If the latter obliquely easy assembly is possible.  

Nach der Montage ergibt sich dann über diese Halte­ vorsprünge eine Einheit.After assembly, this holds protrudes one unit.

Die Erfindung wird anhand von drei Figuren näher erläutert.The invention is illustrated by three figures explained.

Fig. 1 zeigt einen Teilquerschnitt durch ein zwei­ reihiges Schrägkugellager mit dem erfin­ dungsgemäßen Doppelkammkäfig, Fig. 1 shows a partial cross section through a two-row angular ball bearing including the cage OF INVENTION to the invention double comb,

Fig. 2 zeigt den Doppelkammkäfig nach Fig. 1 in radialer Draufsicht im Schnitt, Fig. 2 shows the double comb cage of FIG. 1 in a radial sectional plan view,

Fig. 3 zeigt den Käfig nach Fig. 1 im Schnitt I-I. Fig. 3 shows the cage of Fig. 1 in section II.

Gemäß Fig. 1 umfaßt das zweireihige Schrägkugel­ lager einen einteiligen Außenring 1, zwei Kugel­ reihen 2 und 3, den Doppelkammkäfig 4 und einen zweiteiligen Innenring 5. Wie insbesondere aus Fig. 2 hervorgeht, besteht der zwischen den Kugelreihen 2 und 3 befindliche Käfigringteil 6 aus Verbindungsab­ schnitten 6′, die in der radialen Draufsicht eine sägezahnähnliche Form besitzen. Dadurch ergibt sich in diesem Bereich eine ziehharmonika ähnliche Form, die in Umfangsrichtung sehr elastisch ist. Damit wird die Bewegungsmöglichkeit der Kugeln die in Umfangsrichtung von an den Spitzen 6′′ der Zähne angeformten Stegen 7 geführt werden, wesentlich erhöht.Referring to FIG. 1 comprises the double row angular contact ball bearing comprising a one-piece outer ring 1, two rows of balls 2 and 3, the double comb cage 4 and a two-piece inner ring 5. As can be seen in particular from FIG. 2, the cage ring part 6 located between the rows of balls 2 and 3 consists of cut sections 6 ′ which have a sawtooth-like shape in the radial top view. This results in a concertina-like shape in this area, which is very elastic in the circumferential direction. Thus, the possibility of movement of the balls which are guided in the circumferential direction of the webs 7 formed on the tips 6 '' of the teeth is significantly increased.

Damit sich im nicht montierten Zustand eine Bau­ einheit zwischen dem Außenring 1, den Kugeln und dem Käfig 4 ergibt, besitzen die Stege 7 der einen Kugelreihe 2 die Kugeln hintergreifende Abschnitte 7′. Die Einheit wird bei dem hier zweiteiligen Innenring 5 dadurch vervollständigt, daß der Käfig 4 im Bereich der Verbindungsabschnitte 6′ Vorsprünge 8 besitzt. Wenn letztere in Nuten 5′ des geteilten Laufrings 5 eingreifen, wird dieser zusammen und im Lager gehalten.So that there is a construction unit between the outer ring 1 , the balls and the cage 4 in the unmounted state, the webs 7 of a row of balls 2 have the balls engaging sections 7 '. The unit is completed in the two-part inner ring 5 here in that the cage 4 in the area of the connecting sections 6 'has projections 8 . If the latter engage in grooves 5 'of the split race 5 , this is held together and in the camp.

Wie aus Fig. 3 ersichtlich ist, bilden sowohl die hintergreifenden Abschnitte 7′′ als auch die Dop­ pel-Haltenasen 8 nur lokale Vorsprünge. Dadurch ergibt sich ein leichter Käfig mit zur Montage ausreichend elastischen Vorsprüngen. Die Freiräume 9 zwischen den Verbindungsabschnitten 6′ für zusätz­ liches Schmiermittel sind am besten aus Fig. 2 ersichtlich.As can be seen from Fig. 3, both the engaging portions 7 '' and the double pel-holding lugs 8 only local projections. This results in a light cage with protrusions that are sufficiently elastic for assembly. The free spaces 9 between the connecting sections 6 'for additional Lich lubricant are best seen in Fig. 2.
