Scope
This part of ISO 1122 contains the part of the international vocabulary of gears which is devoted solely
to geometrical definitions of worm gears.
It gives, for each of the geometrical terms relative to gears, a standard definition
which will be valid internationally, the corresponding term being chosen as far as
possible in each language in such a way as to be a direct reflection of the meaning
of the definition.
NOTE Since the choice of the corresponding term can only be partially fulfilled in any
particular language, due to the necessity of respecting certain established conventions,
it is advisable, as far as translation into other languages is concerned, to refer
always to the meaning of the definition itself, rather than to a simple transposition
of the original term.
