German term

topfgetriebe

German to English Tech/Engineering Mechanics / Mech Engineering
Das elastische Zahnrad kann eine topfform aufweisen, wobei es Teil eines Topfgetriebes sein kann.

My specific question is whether there is an English equivalent for the German "Topfgetriebe."
Proposed translations (English)
3 +2 cup-type gear

A "recessed gear" could mean any number of things, other than a gear in the shape of a "pot" or "cup," and a "pot-type/shaped gear" does make more sense. My question, specifically, is whether there is an English term for this, since the German term, when googled, is well represented with images, but I am unable to find an English term for the same images.
philgoddard Apr 13, 2018:
Well, recessed sounds good to me. Pot-type/shaped would work too, though pot on its own sounds a bit odd.
Kphred (asker) Apr 13, 2018:
I have googled this, and I also found that page. Hoping for something more definite.
philgoddard Apr 13, 2018:
Have you Googled this? This is the first hit, and one suggestion is "recessed gear", though it doesn't give references.

cup-type gear

This is a problem. The German term was clearly coined based on the shape of its housing (Topf): "Das Topfgetriebe ist eine Form des Stirnradgetriebes, welche durch die Integration des Getriebes in einem Topfgehäuse gekennzeichnet wird".

The issue is that in English gear nomenclature convention, gears are named for the shape of the teeth or how they move (including pitch, teeth angle, parallel or not to axis of rotation, etc.): spur, bevel, worm, spiral, etc.

The problem with 'pot/cup-shaped gear'' is that this would lead to a misunderstanding of the shape of the teeth. Ovalo (a German manufacturer) seems to use "cup-type gear". Maybe you can explore that....but it has very low hits...although there's one US advertising company that advertises "cup-type gear" similar to the images of Topfgetriebe. This is a start for your research.

Note: further research shows that Harmonic Drive LLC (in the website below) is a subsidiary of Harmonic Drive AG, a German manufacturer (also affiliated with Ovalo). So it seems that this company has coined its own term.

Perhaps a better term in English (adhering to English nomenclature standards) would've been "bevel gear with pot/cup-type housing"...

Errata: I meant "spur gear with pot/cup-type housing" not "bevel gear"
