Kopfkreis

Explanation:
circunferencias de cabeza = Kopfkreis (Ernst)
engrannaje = Verzahnung, Zahneingriff
circulo primitivo = Wälzkreis (Ernst),

circunferencias de cabeza de los engranajes opuestos, radio de la circumference primitiva de la rueda “i” vs. radio de la ***circumference de cabeza de la rueda “i”.

Also:

Auffällig ist dabei, daß der Buchstabe "i" für das Übersetzungverhältnis r1/r2 verwendet wird, was auch dem Wälzkreis 1 / Wälzkreis 2 entspricht.

Referenz: Dubbel, Taschenbuch für den Maschinenbau.

Now the English version:

Tip diameter (outside diameter)of opposed tooth engagements, Rolling circle (circle of contact) "i" vs. gear tip diameter "i".

It is remarkable that the letter "i" is used for the transmission ratio r1/r2, which corresponds also to the ratio of rolling circles 1 to rolling circle 2.

Note: Distinguish between rolling circle and tip circle! Rolling circle is the medium circle. Tip circle is the outer circle.
