Kinematic diagrams - Graphical symbols
The symbols system is intended for simplifying the preparation of diagrams of products in all branches of industry and is to be used in technical documentation as well as in technical and educational literature. It will facilitate the execution and understanding of such diagrams by specialists of different countries. This part contains friction and gear mechanisms and cam mechanisms.
Schémas cinématiques — Symboles graphiques
La présente Norme internationale spécifie les symboles graphiques pour les éléments de schémas cinématiques, englobant les produits de toutes les branches de l'industrie. Il faut employer les symboles spécifiés à l'exécution des schémas de la documentation technique, ainsi que dans la littérature technique et pédagogique. La présente Norme internationale est publiée en trois parties, comme suit: Partie 1 Mouvement des solides de mécanismes 2 Liaisons de deux solides 3 Solides et leurs composants 4 Mécanismes articulés et leurs composants Partie 2 5 Mécanismes à friction et à denture 6 Mécanismes à cames Partie 3 7 Mécanismes à croix de Malte et à rochet 8 Accouplements, embrayages et freins

Overview
ISO 3952-2:1981 - Kinematic diagrams - Graphical symbols - Part 2 defines a standardized system of graphical symbols for kinematic diagrams, focusing on friction and gear mechanisms and cam mechanisms. Published in 1981 by ISO/TC 10 (Technical drawings), this part is one of three in the ISO 3952 series and is intended to simplify the preparation, exchange and interpretation of kinematic schematics across industries and countries.
Key topics
- Scope and purpose: Establishes a uniform symbol system for elements of kinematic diagrams used in technical documentation, engineering drawings and educational literature.
- Symbol content: Covers graphical representations for friction mechanisms, gear trains and gear elements, and cam mechanisms (Part 2). (Part 1 and Part 3 of ISO 3952 address link motion, kinematic pairs, links, Geneva/ratchet mechanisms, couplings and brakes.)
- International application: Symbols designed to aid comprehension by specialists from different countries and to be used consistently in multilingual documentation.
- Standardization context: Developed by ISO/TC 10 and published as an international standard to harmonize engineering drawing practices.
Practical applications
ISO 3952-2 is practical for professionals and organizations that produce, interpret or teach mechanical motion diagrams:
- Mechanical engineers and machine designers documenting drive trains, gearboxes and cam-driven assemblies.
- Draftsmen and technical illustrators creating standardized kinematic schematics for manuals and specifications.
- Technical writers and maintenance engineers preparing repair, assembly and troubleshooting documentation.
- Educators and training providers using consistent graphical symbols in textbooks and course materials.
- CAD/CAM and technical documentation teams developing symbol libraries and templates to ensure cross-border consistency.
Benefits include:
- Faster, clearer communication of kinematic function and element relationships.
- Reduced ambiguity in international projects and component documentation.
- Easier creation of reusable symbol libraries for CAD and publishing.
Related standards
- ISO 3952-1 - Motion of links, kinematic pairs and link components (Part 1).
- ISO 3952-3 - Geneva and ratchet mechanisms; couplings and brakes (Part 3).
- Standards produced by ISO/TC 10 (Technical drawings) govern related graphical conventions.
Using ISO 3952-2:1981 helps organizations standardize kinematic diagrams, improve clarity in engineering drawings, and support consistent documentation of mechanical drives, gear mechanisms, and cam systems worldwide.
