The following charts convert gear pitch dimensional data to the following: Diametral Pitch, Module, Circular Pitch. Module: is the unit of size that indicates how big or small a gear is. It is the ratio of the reference diameter of the gear divided by the number of teeth.

21 lip 2022 · The gear identification chart is designed to help you identify an unknown gear, even if only a few teeth remain intact. The chart has templates for: Diametral Pitch gears from DP8 to DP48. Module gears from Module 3.00 to 0.40. Pressure angles of 14.5º and 20º for both module and diametral pitch.
In the previous pages, we introduced the basics of gears, including 'Module', 'Pressure Angle', 'Number of Teeth' and 'Tooth Depth and Thickness'. In this section we introduce the basic parts of Spur Gears (Cylindrical gears) and dimensional calculations.
Calculate the key dimensions for your external spur gear, such as pitch diameter, root diameter, and outer diameter. Input the gear's tooth count, pitch (or module), and pressure angle, and get the tooth dimensions and manufacturing profile shift coefficient.
This section introduces the dimension calculations for spur gears, helical gears, gear rack, bevel gears, screw gears, and worm gear pairs. Calculations of external dimensions (eg. Tip diameter ) are necessary for processing the gear blanks.
Gears that use diametral pitch (DP) as a unit tooth size are called imperial gears or inch gears. The diametral pitch (DP) is obtained by dividing the number of teeth (z) by the pitch circle diameter (d, in inches).
