Description
DEUTSCHESGERMAN
Die bekannten Kugeln für Ventilsitze bestehen aus einem metallischen Kern bzw. einer metallischen Hohlkugel und einer den Kern bzw. die Hohlkugel einhüllenden Schicht aus Gummi oder gummiartigem Werkstoff. Die Verformung von beispielsweise Eisenblechen zu einer Hohlkugel erfordert eine verhältnismäßig große technische Einrichtung, wie Schneide-, Stanz- und Prägwerkzeuge. Die Herstellung metallischer Hohlkugeln ist ferner verhältnismäßig umständlich, weil die aus den Blechen hergestellten Kugelhälften zusammengeschweißt und die Schweißnähte nachgearbeitet werden müssen. Die Schwierigkeiten wachsen mit der Größe des Durchmessers und der Wandstärke der Hohlkugel. Die Kugeln für Ventilsitze, die Gegenstand der Erfindung sind, haben diese Nachteile nicht.The known balls for valve seats consist of a metallic core or a metallic one Hollow sphere and a layer of rubber or rubber-like enveloping the core or the hollow sphere Material. The deformation of iron sheets, for example, to form a hollow sphere requires a relatively large amount large technical equipment, such as cutting, punching and embossing tools. The manufacture of metallic Hollow balls are also relatively cumbersome because the halves of the ball made from the metal sheets welded together and the weld seams have to be reworked. Difficulties grow with the size of the diameter and the wall thickness of the hollow sphere. The balls for valve seats, which are the subject of the invention do not have these disadvantages.
Die Kugel der Erfindung ist gekennzeichnet durch zwei zusammenhängende Kugelschalen, von welchen die innere aus Hartgummi, die äußere dagegen aus Weichgummi besteht.The ball of the invention is characterized by two connected spherical shells, one of which the inner one made of hard rubber, the outer one made of soft rubber.
Kugeln dieser Art lassen sich auf einfache Weise herstellen. Es hat sich ferner gezeigt, daß solche Kugeln eine hohe mechanische Festigkeit besitzen und praktisch allen Ansprüchen angepaßt werden können, da es keine Schwierigkeiten bereitet, die Wandstärke bei beliebigem Durchmesser der Kugel so zu variieren, daß sie allen mechanischen Beanspruchungen gewachsen ist.Balls of this type can be produced in a simple manner. It has also been shown that such Balls have a high mechanical strength and can be adapted to practically all requirements, since it is not difficult to vary the wall thickness for any diameter of the sphere, that it can withstand all mechanical stresses.
Der Vorteil der erfin dungsgemäß en Kugel liegt darin, daß sie bei verhältnismäßig kleinem Gewicht eine hohe mechanische Festigkeit aufweist.The advantage of the ball according to the invention is that it is relatively light in weight has a high mechanical strength.
Die Wandstärke kann völlig gleichmäßig gehalten und dadurch eine stets zentrale Schwerpunktlage erzielt werden.The wall thickness can be kept completely uniform and thus a central position of the center of gravity can always be achieved will.
Eine beispielsweise Ausführungsform einer solchen Kugel ist in der Zeichnung veranschaulicht. Es zeigt Fig. 1 eine Kugel in der Ansicht, Fig. 2 eine Kugel im Schnitt.An example embodiment of such a ball is illustrated in the drawing. It shows Fig. 1 is a view of a sphere, and Fig. 2 is a section of a sphere.
Zur Herstellung erfmdungsgemäßer Kugeln werden zunächst zwei Kugelhälften aus vor- oder nicht vorvulkanisierten Hart- bzw. Weichgummifellen gebildet; wenn es sich um kleine Kugeln handelt, können die Kugelhälften durch Verpressen von den Kugelhälften angepaßten Zuschnitten hergestellt werden, indem man zwei aus Hart- bzw. Weichgummi bestehende Zu- schnitte in eine der gewünschten Kugelgröße entsprechende Form gibt und die beiden Zuschnitte durch einen Stempel zu einer Halbkugel verpreßt. Bei größeren Kugeln müssen die Kugelhälften aus Seg-Kugel für VentilsitzeTo produce balls according to the invention, two halves of the ball are first formed from pre-vulcanized or non-pre-vulcanized hard or soft rubber sheets; if it is small balls, the ball halves may be prepared by compression of the ball halves adapted blanks by two composed of hard and soft rubber blanks are in a corresponding one of the desired ball size and shape, the two blanks by a plunger to pressed into a hemisphere. For larger balls, the halves of the ball must be made from Seg balls for valve seats

menten zusammengesetzt werden. Das Pressen erfolgt vorteilhafterweise unter Anwendung von Wärme, wobei bereits eine teilweise Verbindung des Hartgummis mit dem Weichgummi eintritt. Dann werden zwei Kugelhälften zu einer Kugel zusammengesetzt, nachdem vorher in eine Kugelhälfte ein Treibmittel, z. B. Ammoniumcarbonat, gegeben ist. Die Kugel wird in einer Form in der Wärme ausvulkanisiert. Durch das Treibmittel wird der für die Herstellung einer runden Kugel erforderliche Preßdruck erzielt; durch die Einwirkung der Wärme und des Druckes verbinden sich die beiden Kugelhälften zu einer völlig geschlossenen Kugel.ments are put together. The pressing is advantageously carried out with the application of heat, wherein a partial connection of the hard rubber with the soft rubber already occurs. Then there will be two Ball halves assembled into a ball after a propellant, z. B. Ammonium carbonate, is given. The ball is fully vulcanized in a mold in the heat. By the propellant is used to achieve the pressure required to produce a round ball; by the effects of heat and pressure combine the two halves of the ball into one completely closed ball.
