Description

Scheibenförmiger Gußkörper Die Erfindung bezieht sich auf scheibenförmige gegossene Maschinenelemente, wie Zahn- oder Laufräder, Bremsteller, Kupplungsscheiben o. dgl., bei denen das Drehmoment durch einen Kranz von Verbindungsschrauben auf einen zweiten Körper übertragen wird. Die Verbindungsschrauben werden nun bisher in Augen, gelagert, die, wie in Abb. z gezeigt, sich unmittelbar an den Laufkranz und den Mittelsteg anschließen.. Im dargestellten Beispiel ist ein Laufrad t in Verbindung mit einem Zahnrada dargestellt, jedoch ist die Bauart grundsätzlich bei allen beispielsweise aufgeführten Maschinenelementen dieselbe. Das Laufrad besitzt Augen 3, in denen die Gewindebolzen q. mit den Druckringen 5 liegen. Durch Anziehen der Muttern 6 dieser Schrauben werden Zahnrad und Laufrad aneinander befestigt.Disc-Shaped Cast Body The invention relates to disc-shaped Cast machine elements such as toothed wheels or running wheels, brake plates, clutch disks o. The like. In which the torque is increased by a ring of connecting screws a second body is transferred. The connecting screws are now so far in eyes, which, as shown in Fig. z, are directly attached to the tread and connect the center bar. In the example shown, an impeller is t in Connection with a toothed wheel shown, but the design is basically at all machine elements listed for example the same. The impeller has Eyes 3 in which the threaded bolts q. with the pressure rings 5 lie. By tightening the nuts 6 of these screws are attached to the gear wheel and impeller.

Die Abbildung zeigt deutlich die große Ouerschnittsfläche an den Augen. Durch die Querschnittsanhäufung werden bei gegossenen Rädern Lenkerbildung und Gußspannungen hervorgerufen.The figure clearly shows the large cross-sectional area on the eyes. The accumulation of cross-sections results in link formation and casting stresses in cast wheels evoked.

Nach der Erfindung lassen sich diese Mängel vermeiden, wenn man die Augen anders gestaltet. Wie in Abb. a und 3 dargestellt, werden die Augen als verhältnismäßig schwache Platten 6, etwa von der Stärke des Mittelstegs 7, ausgebildet und in einiger Entfernung von der Scheibe angeordnet. Die Verbindung mit dieser wird durch Stege und Rippen g hergestellt.According to the invention, these shortcomings can be avoided if the Eyes designed differently. As shown in fig. A and 3, the eyes are considered proportionate weak plates 6, approximately the thickness of the central web 7, formed and in some Distance from the disc arranged. The connection with this is made by webs and ribs g made.

Wie Abb. a zeigt, ist bei dieser Bauart jegliche Querschnittsanhäufung vermieden worden, das Material ist gleichmäßig verteilt. Die Lagerung der Verbindungsschrauben ist dabei ebenso sicher und zuverlässig wie bei früheren Bauarten, die Bearbeitung bleibt ebenso einfach. Man erhält aber den wesentlichen Vorteil, daß Lenkerbildungen und Gußspannungen auf ein Mindestmaß herabgesetzt werden können, die Teile also auch wirklich die ihuen zugrunde gelegten B;eilastwngen aushalten und Ausschuß vermieden wird.As Fig. A shows, with this type of construction there is any accumulation of cross-sections been avoided, the material is evenly distributed. The storage of the connecting screws the machining is just as safe and reliable as with earlier designs remains just as simple. But you get the essential advantage that link formations and casting stresses can be reduced to a minimum, so the parts really withstand the basic loads on which they are based and avoid rejects will.

Claims (1)

PATENTANSPRUCFI: Scheibenförmiger Gußkörper, wie Zahn-oder Laufrad, Bremsteller o. dgl., bei welchem das Drehmoment durch einen Kranz von Verbindungsschrauben auf einen zweiten Körper übertragen wird, dadurch gekennzeichnet, daß die Augen für die Verbindungsschrauben nicht direkt auf dem Mittelsteg oder dem Kranz aufsitzen, sondern plattenförmig ausgebildet und nur durch Rippen und Querstege mit der Scheibe verbunden sind.PATENT CLAIM: Disc-shaped cast body, such as toothed or impeller, Brake plate or the like, in which the torque is controlled by a ring of connecting screws is transferred to a second body, characterized in that the eyes do not sit directly on the center bar or rim for the connecting screws, but rather plate-shaped and only through ribs and crossbars with the disc are connected.
