TS 3350

TS 3350 is a terminology standard that organizes the terms and symbols used for gears in a single technical framework. Gears are widely used in machine systems for power transmission, speed reduction, direction change, and precise motion control. The focus of this standard is to make the language of gear geometry and related notation consistent and unambiguous.

Why shared gear terminology matters

In precision machine components such as gears, differences in naming can lead to misreading drawings, catalogs, and engineering communication. A common terminology and symbol set helps ensure that concepts such as module, tooth count, pitch, pressure angle, and related terms are understood in the same technical sense. This supports consistency in design, manufacturing, inspection, and maintenance.

The general role of symbols and notation

In a broader technical context, symbols shorten long definitions and improve readability in formulas, calculations, and drawings. For gears, standardized symbols provide a uniform way to express geometric quantities, ratios, and other characteristic parameters. This standard covers gear terms and symbols; the summary here reflects the general technical subject rather than the full set of detailed rules or application provisions in the standard text.

• Supports a shared technical language for gears.
• Helps interpretation of drawings, calculations, and documentation.
• Promotes consistent naming of gear geometry and performance concepts.
• Provides a reference framework aimed at reducing terminology confusion in mechanical engineering practice.
