WebMay 14, 2024 · Standard modules for straight and helical gears are defined by ISO 54:1996 and indicate the amount of pitch diameter (or pitch length, in the case of a straight rack) that each tooth occupies. The larger the module, the larger the gear teeth and the overall gear. m = module (mm) d = pitch diameter or pitch length (mm) n = number of teeth WebCalculate 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. The default Manufacturing Profile Shift Coefficient is 0.
