The advantage of herringbone gears is the elimination of thrust, but bevel gears would have thrust with or without herringbones, and besides, with modern materials and bearings, thrust is not a big deal.

If you really need this, maybe you could get creative with a 3D modeller, and knit together two pairs of spiral bevel gears?

| need them because i will be using them in my rc helicopters for extreme speeds.

Why ??

You need to show a valid reason why and a commitment to make some and use them.
Art has enough on his plate doing mainstream modules and not following flights of fancy.

This happened over at mach 3
"Can we have this Art please I really need it. Art writes it and 6 months down the line someone unrelated to the original post tries it and it's broken and has been broken all the while but where is the OP ?

You mean you youd like to have the ability to have herringbone teeth on a bevel?

Ill look into it....

What if we have Bevel Herringbone in bevel gears.
