REPRESENTATION OF GEARS 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 chain line. Teeth - Specify the teeth profile either by reference to a standard or by a drawing to a suitable scale. If it is essential to show one or two teeth on the drawing itself draw them as thick continuous lines
Bevel gear Root Spiral gear
- If mating gears are represented, the direction of the teeth should he shown on one gear only.
