Technical drawings - Conventional representation of gears (ISO 2203:1973)

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.

Technische Zeichnungen - Darstellung von Zahnrädern (ISO 2203:1973)

Diese Norm legt die herkömmliche Darstellung der gezahnten Teile von Zahnrädern einschließlich Schnecken- und Kettenrädern fest. Sie gilt für Teilzeichnungen und Zusammenstellungszeichnungen. Ein Zahnrad wird grundsätzlich (ausgenommen in Schnittdarstellungen) als ein ganzes Teil ohne einzelne Zähne dargestellt, aber die Bezugsfläche wird als schmale Strichpunktlinie hinzugefügt.

Dessins techniques - Représentation conventionnelle des engrenages (ISO 2203:1973)

La présente Norme Internationale établit une représentation conventionnelle des dentures des engrenages, ainsi que des vis sans fin et des roues à chaîne. Elle s'applique aux dessins de détail et dessins d'ensemble. Selon les principes de base, une roue d'engrenage est représentée (sauf en coupe axiale) comme une pièce pleine non dentée, avec pour seule adjonction, le tracé de la surface primitive, en trait mixte fin.  
NOTE -- Pour des raisons d'uniformité, dans la présente Norme internationale, les figures sont en projection du premier dièdre (Méthode E). Il est entendu que les principes établis s'appliquent également à la projection du troisième dièdre (Méthode A).

FOREWORD Is0 (the International Organization for Standardization) is a worldwide federation of national standards institutes (IS0 Member Bodies). The work of developing International Standards is carried out through IS0 Technical Committees. Every Member Body interested in a subject for which a Technical Committee has been set up has the right to be represented on that Committee. International organizations, governmental and nongovernmental, in liaison with ISO, also take part in the work. Draft International Standards adopted by the Technical Committees are circulated to the Member Bodies for approval before their acceptance as International Standards by the IS0 Council. International Standard IS0 2203 was drawn up by Technical Committee lSO/TC IO, Technical drawings, and circulated to the Member Bodies in January 1971. It has been approved by the Member Bodies of the following countries : Australia Austria Belgium Canada Chile Czechoslovakia Denmark Egypt, Arab Rep. of France Germany Greece Hungary India Ireland Israel Italy Japan Korea, Dem.P.Rep. of Korea, Rep. of Netherlands New Zealand Norway No Member Body expressed disapproval of the document.

INTERNATIONAL STANDARD IS022034973 (E) Technical drawings - Conventional representation of gears 1 SCOPE AND FIELD OF APPLICATION This International Standard establishes the conventional representation- of the toothed portion of gears including worm gearing and chain wheels. It is applicable to detail drawings and assembly drawings. 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. NOTE - For uniformity all figures in this international Standard are in first angle projection (Method EL It should be understood that the third angle projection (Method A) could equally well have been used without prejudice to the principles established. 2 DETAIL DRAWINGS (INDIVIDUAL GEARS) 2.1 Contours and edges Represent the contours and the edges of each gear (see Figures 1,2 and 3), as if they were, - in an unsectioned view, a solid gear bounded by the tip surface; - in an axial section, a spur gear having two diametrically opposed teeth, represented unsectioned, even i
