Worm gear material |
Does anyone know the chemical composition and mechanical properties of
Rd65 VL22 Copper alloy. Or where I could get it from. Also the
Standard from which this material comes from would be useful.
I have searched the internet and am unable to find its specification.
Thanks,
Martin

Copper and zinc make brass. You did a lot better than I did. I could find
no listing of anything useful on google with the information supplied.
Good work!

I thought 9 copper : 1 tin was brass. And that 1 copper : 9 tin was bronze.
I thought some math textbook from when I was a kid said this. Maybe 9
copper : 1 tin for BRONZE would be okay, judging by a few internet pages.
Is there some other thing which is 10% copper, 90% tin? I saw some mention
of pewter with this kind of ratio. To the OP's question, I didn't even know
that worms had gears.

Brass is a Cu--Zn alloy
And that 1 copper : 9 tin was bronze.
Bronze is a Cu--Sn alloy.

No. Copper-zinc alloy is brass, in "any" proportion. Don't use brass in
vacuum, as zinc has a vapor pressure.
Copper-tin alloy is bronze.

Mechanical ones do!

I guessed that the Rd65 part might refer to the percentage of Copper (or
something like that) and deleted it from the search. eg

1) The VL22 is a special gear bronze - a bronze gear alloy with apprently no
lead. Aka known as Aeterna (the mfg?)
2) Are you sure about the R "d" 65? If it is actually a "b", that would be
the hardness used in bronze gears. The D scale is a lot harder than the C
used for steel or the B used for bronze. The D would show up if the bronze
was somehow face-hardened.
3) I think, but I wouldn't bet the house, that it is from a French or German
mfg
4) If you had a CDA (Copper development Association) number for the alloy,
the alloy that was registered by the manufacturer to get a number, it would
help a lot.

You are possibly mistaken in thinking this designates a
copper/brass/bronze alloy.
Accordingly, you could go with an engineering approach:
what material would I like for a worm?
A phosphor bronze, likely
Brian Whatcott Altus OK

I dont think that "Rd65 VL22 Copper alloy" is an ASTM designation. This
could be a trade name or part number. Not sure.
I would try to find some worm gear manufacturers online and see which alloys
they use. I'm betting it's ChromeVanadium Steel.
If it's a copper alloy, it might be an Aluminum Bronze, which is frequently
used for gears.
