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.
