Calculate the key dimensions for your external spur gear. Input the gear's tooth count, pitch (or module), and pressure angle to calculate the pitch diameter, root diameter, and outer diameter. This also generates the tooth dimensions: addendum, dedendum, working depth, and whole depth.
Spur Gear design formula for geometry, pitch, tooth clearance and critical functional data. (Inch Units Applicable for Constants) Spur Gear Design Calculator. Where: φ = Pressure Angle a = Addendum a G = Addendum of Gear a P = Addendum of Pinion b = Dedendum c = Clearance C = Center Distance D = Pitch Diameter D G = Pitch Diameter of Gear
The diametral pitch calculator quickly converts between module, diametral pitch, and circular pitch. A gear's pitch and number of teeth determine the overall size of the gear (and the blank you need to make that gear).
I wrote this calculator after getting frustrated with the number of calculators on the web that focus on antiquated diametral pitch based gears rather than modern module gears. To use the calculator, enter the module and number of teeth and the rest of the table should automatically update.
Spur Gear Calculator and Generator - Download DXF, SVG or CSV Excel format files. Simular: Spur Gear and assembly Builder. Spur Gear Generator is unitless: you may choose inches, cm or millimeters when importing your DXF file as you will have the same value for D/P as it is set above or as imported (SI or imperial nits).
This calculator helps engineers and designers to accurately determine the pitch diameter of helical gears, facilitating optimal gear design and application.
Use the calculator below to figure out various gear specifications given two of the following; tooth count, diameter, and/or pitch. Calculate the approximate (?) distance between the two gear shafts. Pitch conversion table.

This calculator will determine the following design variables for a gear and pinion: Transverse DP, Circular Pitch, Module, Pressure Angle, Pitch Diameter
In this section we introduce the basic parts of Spur Gears (Cylindrical gears) and dimensional calculations. The size of gears is determined in accordance with the reference diameter (d) and determined by these other factors; the base circle, Pitch, Tooth Thickness, Tooth Depth, Addendum and Dedendum.
