  Bogenförmiger Zahn für   Stirn- und Kegelräder.   



   Bogenförmige Zähne sind an sich bekannt und bieten gegenüber geraden Zähnen den Vorteil, dass sie wie die Pfeilräder mit vergrössertem, stossfreiem Eingriff und ohne einseitigen Axialdruck arbeiten, dabei aber einen noch   ruhigeren Gang u d leichter erreichbare vollkommene Zahn   anlage als die Pfeilräder besitzen. 



   Die Erfindung besteht in einer besonderen Ausführungsform eines derartigen bogenförmigen Zahnes. 



   Jede Satzräderverzahnung ist durch die Form des Zahnstangenzahnes des Satzes vollkommen bestimmt, denn nach der Verzahnungstheorie kann man zu einem bekannten Zahn- 
 EMI1.1 
   sämtlicher Räder des Matzes ergeben,   da diese sämtlichen Rädern des Satzes   genuin   sind. 



   Während nun die Flankenfläche eines geraden Evolventen-Zahnstangenzahnes eine Ebene darstellt, wird sie bei dem bekannten kreisbogenförmig gekrümmten Zahn zu einem Zylindermantelausschnitt. Denkt man sich einen solchen Zahn durch   Zusammenlegung   unendlich vieler Zähne minimaler Breite entstanden, so besitzt jeder Teil nach wie vor dieselbe korrekte 
 EMI1.2 
 verschoben. 



   Die Zähne einer Zahnstange bzw. eines   Plankegpirades   (Kegelrad. dessen Kegelwinkel 
 EMI1.3 
 der   Zahnstangennanke   ist also die neue Zahnform des ganzen Satzes   gekennzeichnet   und voll- ständig bestimmt. 



   Fig. 1 zeigt, einen derartigen Zahn im Querschnitt bzw. in Ansicht und Fig. 2 in Draufsicht.

  Arch-shaped tooth for spur and bevel gears.



   Arch-shaped teeth are known per se and have the advantage over straight teeth that they work like the arrow wheels with enlarged, shock-free engagement and without one-sided axial pressure, but have an even smoother gear and more easily accessible perfect tooth system than the arrow wheels.



   The invention consists in a particular embodiment of such an arcuate tooth.



   Each set of gear teeth is completely determined by the shape of the rack tooth of the set, because according to the gear theory you can get to a known tooth
 EMI1.1
   of all the wheels of Matz, since all of the wheels of the set are genuine.



   While the flank surface of a straight involute rack tooth represents a plane, it becomes a cylinder jacket section in the case of the known circularly curved tooth. If one imagines such a tooth was created by merging an infinite number of teeth of minimal width, then each part still has the same correct one
 EMI1.2
 postponed.



   The teeth of a toothed rack or a Plankegpirad (bevel gear. Its cone angle
 EMI1.3
 the rack edge is thus the new tooth form of the whole set marked and completely determined.



   Fig. 1 shows such a tooth in cross section or in view and Fig. 2 in plan view.
