Abstract

Zahnradverzahnung aus Zahnköpfen und Zahnfüßen, die von Kurven zweiter oder höherer Ordnung gebildet werden, wobei die Kurven an ihren Enden tangential aufeinander zu weisen und wenigstens die Kurven, die die Zahnköpfe (3k) bilden, oder wenigstens die Kurven, die die Zahnfüße (3f) bilden, keine Zykloiden sind.

Figure 00000001
Gear teeth made of tooth heads and tooth bases, which are formed by curves of the second or higher order, the curves pointing tangentially at their ends and at least the curves forming the tooth heads (3k) or at least the curves forming the tooth bases (3f) form, are not cycloids.
