Geometrical design and strength check of common chain transmissions using roller chains. The application works with many 2D and 3D CAD systems and includes corresponding databases of roller chains. The calculations use data, procedures and algorithms from ANSI/ASME, ACA (American Chain Association) ISO, DIN, BS and JIS. Application is developed in MS Excel, is multi-language and supports Imperial and Metric units.

The calculation is developed for geometrical designs of belt and chain transmissions with more sprocket wheels (max. 15). It solve the necessary length of the belt (chain) using known positions and diameters of sprocket wheels. Application is developed in MS Excel, is multi-language, supports Imperial and Metric units and support many 2D CAD systems. (AutoCAD, AutoCAD LT, IntelliCAD, TurboCAD...).

The GD and T Trainer Professional Edition is a virtual classroom in the fundamentals of geometric dimensioning and tolerancing. This computer-based training program contains 28 interactive lessons, quizzes, and a final exam. It provides instant lesson feedback, technical animations that demonstrate concepts, and audio narration. Also, includes over 100 author's comments that give tolerancing insights from GD and T expert Alex Krulikowski.
