Description

  

  Verfahren zur Herstellung von Kugelführungen für Kugellager und nach dem  Verfahren hergestellte Kugelführung.    Vorliegende Erfindung betrifft ein Ver  fahren zur Herstellung von     Kugelführungen     für Kugellager     und    eine nach dem Verfahren  hergestellte Kugelführung.  



  Gemäss dem Verfahren werden Formplatten       verwendet,    in     denen    Aussparungen für den  Führungskörper und genau passende Lager  für die vom Führungskörper vorstellenden  Kugelteile ausgearbeitet sind, in welche Lager  die Kugeln eingelegt werden, worauf der  Fihrungskörper aus Metall in einem Stück  um die Kugeln gegossen wird.  



  Fig. 1 zeigt beispielsweise einen Quer  schnitt durch Teile der Giessform für die  Kugelführung ei les Drucklagers (Schräglager).  Sie besteht aus zwei ringförmigen Formplatten  1, 2. In diesen Platten sind nebst den     Aus-          s    s parungen für den Führungskörper Lager 3  ausgearbeitet und     blank    poliert für diejenigen  Teile der Kugeln, die bei der fertig gegossenen  Führung von dieser vorstellen. Die Platten  sind so zueinander angeordnet, dass je zwei  korrespondierende Lager für eine Kugel  einander genau gegenüberliegen.

   Vor den  Giessen der Führung werden die Kugeln in    die Lager eingesetzt und sodann der     Fübrungs-          körper    durch Eingiessen flüssigen Metalles durch  den Eingusskanal 4 gegossen. Als Material  für den Führungskörper wird vorteilhafter  weise Lagermetall verwendet, das selbst  schmierend wirkt.

   Da die Stahlkugeln in der  Giessform eine niedrigere Temperatur haben  als diejenige des Metalles, das in die Form       gegossen    wird, findet ein     verhältnismässig     rasches Abschrecken des flüssigen Metalles  um den Kugelumfang statt, dadurch entsteht  genügend Toleranz;

   dass sich die Kugeln in  den Lagern der     Führung    leicht drehen     könne .     Da die     blank    polierten Kugelflächen     als    Form  teile für die Lagerflächen für die Kugeln der  Kugelführung     dienen,    werden beim     Giessen     blank polierte     Lagerflächen    für die Kugeln  erzielt.     L-in    einen möglichst kompakten und  homogenen     GUB    zu erzielen, ist es vorteilhaft,  das     flüssige        Metall    unter Druck in die Giess  form einzuführen.

       Fig.    ? zeigt beispielsweise       einen    Querschnitt durch Teile der     Giessform     für die     Kugelführung    eines Drucklager, bei  welcher der     Führungsring        aussen    und innen  mit einer Verstärkungsrippe 5 versehen ist.      Ohne weiteres ist ersichtlich, dass, je nach  der Wahl der Bearbeitung der Giessform,       Führungen    für die Kugeln erzeugt werden  können, die die     einzelnen    Kugeln mehr oder  weniger umfassen.  



  Fig. 3 zeigt beispielsweise einen     Quer-          schntt    durch einen Teil eines Kugellagers,  dessen Führung für die Kugeln durch die  (iefform gemäss Fig.1 hergestellt worden ist.  Hiebei sind G und 7 die Lagerringe, 8 der  Kugelführungskörper und 9 die Kugeln. Fig. 4  ist dieselbe Kugelführung in Draufsicht mit  den in ihr gelagerten Kugeln.  



  Fig. 5 zeigt beispielsweise einen Quer  schnitt durch Teile eines Achsial-Druckkugel  lagers; hiebei bedeuten 10 und 11 die Lager  ringe, 12 den Kugelführungskörper und 13  die Kugeln. Der Kugelführungskörper mit  den Kugeln dieses Lagers ist in Draufsicht  in Fig. 6 dargestellt.  



  Die Kugelführung gemäss der Erfindung  eignet sich nicht nur für die Lagerung rotie  render Körper, sondern auch für solche mit  geradliniger Bewegung. Die Fig. 7 und 8  zeigen beispielsweise eine solche Kugelführung  in Ansicht, deren Konstruktion ohne weiteres  aus den Figuren ersichtlich ist.  



  Das vorliegende Verfahren zur Herstellung  von Kugelführungen für Kugellager hat gegen  über der Herstellungsmethode von Kugel  führungen die aus Blech ein- oder zweiteilig  hergestellt sind, die Vorteile, dass selbst  schmierende Lagermetalle verwendet werden  können. Die Kugeln werden auf einer ver  hältnismässig grossen Fläche genau passend    und unverrückbar geführt, daher geringer  spezifischer Druck auf die Lager der Führung,  wodurch hinwiederum geringe Abnützung der  Führungslager resultiert. Weiter ist eine  genaue Distanzierung der Kugeln möglich  und die Verwendung einer grösseren Kugelzahl  bei gleichem Luftkreisdurchmesser. Da der       Führungskörper    gegossen ist, kommen Abfälle  nicht in Betracht und ist daher die Herstel  lung, bei Erzeugung gröberer     Mengen,    billiger.

    Eine     Abnützung    der     Griessform    tritt nicht in  dem Male ein, wie diejenige der     Stanzwerk-          zeuge    bei der     Herstellung    der Blechringe für  die Kugelkäfige. Montagekosten, die beim  Zusammensetzen aus einzelnen Stücken be  stehender     Kugelführungsringe    entstehen,  kommen hier in Wegfall.



  Process for the production of ball guides for ball bearings and ball guide produced by the process. The present invention relates to a process for producing ball guides for ball bearings and a ball guide produced by the method.



  According to the method, mold plates are used in which recesses for the guide body and exactly matching bearings are worked out for the ball parts protruding from the guide body, in which bearings the balls are inserted, whereupon the metal guide body is cast in one piece around the balls.



  Fig. 1 shows, for example, a cross section through parts of the mold for the ball guide ei les thrust bearing (angular contact). It consists of two ring-shaped shaped plates 1, 2. In addition to the recesses for the guide body, bearings 3 are worked out and polished bright for those parts of the balls that are present in the finished cast guide in these plates. The plates are arranged in such a way that two corresponding bearings for a ball are exactly opposite one another.

   Before the guide is cast, the balls are inserted into the bearings and then the guide body is cast by pouring liquid metal through the pouring channel 4. The material used for the guide body is advantageously bearing metal that has a self-lubricating effect.

   Since the steel balls in the casting mold have a lower temperature than that of the metal that is poured into the mold, the liquid metal is quenched relatively quickly around the circumference of the ball, which creates sufficient tolerance;

   that the balls can turn easily in the bearings of the guide. Since the brightly polished spherical surfaces serve as shaped parts for the bearing surfaces for the balls of the ball guide, brightly polished bearing surfaces for the balls are achieved during casting. To achieve a GUB that is as compact and homogeneous as possible, it is advantageous to introduce the liquid metal into the casting mold under pressure.

       Fig.? shows, for example, a cross section through parts of the casting mold for the ball guide of a thrust bearing, in which the guide ring is provided with a reinforcing rib 5 on the outside and inside. It can readily be seen that, depending on the choice of machining of the casting mold, guides can be produced for the balls which more or less encompass the individual balls.



  FIG. 3 shows, for example, a transverse section through part of a ball bearing, the guidance of which for the balls has been produced by the oval shape according to FIG. 1. Here, G and 7 are the bearing rings, 8 are the ball guide bodies and 9 are the balls. 4 is the same ball guide in plan view with the balls mounted in it.



  Fig. 5 shows, for example, a cross section through parts of an axial thrust ball bearing; here mean 10 and 11 the bearing rings, 12 the ball guide body and 13 the balls. The ball guide body with the balls of this bearing is shown in plan view in FIG.



  The ball guide according to the invention is suitable not only for the storage of rotating bodies, but also for those with linear movement. 7 and 8 show, for example, a view of such a ball guide, the construction of which is readily apparent from the figures.



  The present method for producing ball guides for ball bearings has the advantages that self-lubricating bearing metals can be used compared to the production method of ball guides which are made of sheet metal in one or two parts. The balls are guided precisely and immovably over a relatively large area, so there is little specific pressure on the guide bearings, which in turn results in little wear on the guide bearings. It is also possible to precisely distance the balls and to use a larger number of balls with the same air circle diameter. Since the guide body is cast, waste is out of the question and is therefore cheaper to produce when producing larger quantities.

    The semolina does not wear out in the same way as that of the punching tools during the manufacture of the sheet metal rings for the ball cages. Assembly costs that arise when assembling individual pieces of existing ball guide rings are eliminated here.
