This file contains a technical diagram illustrating the components and specifications of a gear tooth. The diagram includes a detailed three-dimensional schematic labeling key features such as the addendum, dedendum, face width, pitch surface element, working depth, flank, pitch circle, tooth thickness, tooth space, circular pitch, total depth, clearance, and clearance circle. The root or dedendum circle and circular pitch are also identified as critical measurement parameters. The diagram employs arrows and labels to clearly identify each geometric element and dimensional aspect of the gear tooth structure.

The photograph below the schematic provides a practical reference showing five different gear assemblies of varying sizes positioned against a ruler marked in inches. The gears range from approximately 1 to 2 inches in width and display different tooth configurations and shaft orientations, illustrating the dimensional scale and physical appearance of actual gear components that correspond to the technical specifications depicted in the accompanying diagram above.
