About This Item
TS ISO 1122-2 is the second part of the Vocabulary of gear terms series, focused on definitions related to worm gear geometry. As a terminology standard, it helps establish consistent use of core concepts such as worm, worm wheel, pitch, helix and related geometric terms, so that design documents, drawings, manufacturing notes and technical discussions use the same meaning. In practical terms, it supports a common technical language for worm gearing.
Why worm-gear geometry needs precise terminology
Worm gear sets are commonly used in power transmission where compact size and high reduction ratios are important. Their geometry is conceptually different from spur or helical gearing, because the worm and worm wheel interact through a screw-like motion and specialized contact geometry. In general technical context, clear definitions matter because terms such as pitch, lead, helix and tooth form are easy to confuse if they are not standardised. This part of the vocabulary addresses that conceptual boundary.
What this kind of standard helps organise
- Terminology consistency in drawings, specifications and catalogues.
- Clearer communication between designers, manufacturers and inspectors.
- A shared reference for training and technical documentation.
- Separation of worm-gear terms from broader gear vocabulary.
