Establishes how to draw the toothed portion of gears including worm gearing and chain wheels. Applicable to detail drawings (individual gears) and assembly drawings (gear pairs). As a fundamental principle a gear is represented (except in axial section) as a solid part without teeth, but with the addition of the pitch surface in a thin long dash-and-dot line. For uniformity all figures are in first angle projection.
