Is it not ASME Y14.7.1 & ASME Y14.7.2?

If you are in ISO part of the world you may be interested in:

ISO 701:1998 International gear notation -- Symbols for geometrical data

ISO 1122-1:1998 Vocabulary of gear terms -- Part 1: Definitions related to geometry

ISO 1122-2:1999 Vocabulary of gear terms -- Part 2: Definitions related to worm gear geometry

Kimo05,

You should chat with your manufacturers. A lot of manufacturers like to make custom worm gears as a set in which you call up the tooth clearance. Either the manufacturer makes both pieces, or you supply the off-the-shelf worm you intend to use.

They can also tell you what standard they like to follow.
