Drücker für Zylindermaschine a is einem Teil gegossen mit Präzisionskugellager und verschraubtem Kreuzgelenk.Pusher for cylinder machine a is cast in one piece with precision ball bearing and screwed universal joint.
Die feuerung bezieht sich auf einen Drücker für Zylindermaschine, welcher aus einem Teil in Rotmessing gegossen ist. Dadurch ist es möglich, den Drücker wesentlich leichter als bisher zu gestalten, und er passt farblich zu Goldmessing,The firing refers to a pusher for a cylinder machine, which is cast in one piece in red brass. This makes it possible to make the pusher much lighter than before, and its color matches the gold brass,
Bisher wurden drücker aus drei Teilen ( Drückerhebel, Drückerplatte, Achse) hergestellt und miteinander verlötet. Until now, pushers were made from three parts (push lever, push plate, axle) and soldered together.
Die bisherigen Kreuzgelenke haben einen Durchmesser von 5-6mm und sind mit den Drückerhebel und der Übertragungsstange mit einem Stahlstift von 3- 3.5mm vernietet. Dies wirkt sich sehr negativ auf Gewicht und Präzision des Drückers aus.The previous universal joints have a diameter of 5-6mm and are riveted to the pusher lever and the transmission rod with a steel pin of 3-3.5mm. This has a very negative effect on the weight and precision of the pusher.
Der Neuerung liegt die Aufgabe zugrunde, diesen Nachteil auszuschalten.The aim of the innovation is to eliminate this disadvantage.
Die Aufgabe wird dadurch gelöst, daß das Kreuzgelenk einen Durchmesser von 4mm hat und nicht mit einem Stahlstift vernietet ist, sondern spielfrei auf einer 2rnm starken Achse { wahlweise Messing oder Neusilber) läuft und nicht vernietet sondern mit Schrauben gesichert ist.The task is solved by the fact that the universal joint has a diameter of 4mm and is not riveted with a steel pin but runs without play on a 2mm thick axle (optionally brass or nickel silver) and is not riveted but secured with screws.
Die Übertragungsstange besteht aus Rundmaterial von 2mm Durchmesser, nicht wie bisher mit 3mm Durchmesser. Dies hat den Vorteil, daß es wesentlich leichter ist und die Leichtgängigkeit positiv beeinflußt.The transmission rod is made of round material with a diameter of 2 mm, not 3 mm as before. This has the advantage that it is significantly lighter and has a positive effect on the smooth running.

Gemäß dem jetzigen Stand der Technik, bestehen die Kugelgelenke, welche die Übertragung der Bewegung von der Übertragungsstange zum Flügel bewirken, aus einem durchbohrtem Kugelgelenk welches in einer Kugelpfanne( Kupfer- oder Mepcinglager) läuft.According to the current state of the art, the ball joints, which transfer the movement from the transmission rod to the wing, consist of a drilled ball joint which runs in a ball socket (copper or Mepcing bearing).
Diese Version der Kugelgelenke hat sich nicht als zweckmässig erwiesen, da sich durch die ständige beanspruchung der Kugelgelenke die Anschlagränder der Kugelpfanne abnutzen und das Gelenk somit Spiel bekommt und Geraeusche verursacht.This version of the ball joints has not proven to be practical because the constant stress on the ball joints causes the stop edges of the ball socket to wear down and the joint therefore becomes loose and causes noise.
Das Problem wird dadurch gelöst, daß statt des Kugelgelenks ein Miniatur- Präzisionskugellager, welches in einer Messing oder Neusilberführung gehalten wird, verwendet wird. Ein Kugellager unterliegt nicht den bei Kugelgelenken, welche in einer Kugelpfanne laufen bekannten Verschleiüerscheinungen.The problem is solved by using a miniature precision ball bearing instead of a ball joint, which is held in a brass or nickel silver guide. A ball bearing is not subject to the wear and tear that is common with ball joints that run in a ball socket.
Eine wesentliche Verbesserung gegenüber dem jetzigen Stand der Technik ist die wesentliche feinere und leichtere Ausführung welche durch die im Gußverfahren hergestellte Form und Material sich positiv auf Gewicht und Leichtgängigkeit auswirkt.A significant improvement over the current state of the art is the significantly finer and lighter design, which has a positive effect on weight and smooth running thanks to the shape and material produced using the casting process.
