The gear rack calculator calculates calculates the key dimensions for a gear rack. Based on the module (or diametral pitch) you can easily get the gear tooth dimensions, including addendum, dedendum, whole depth, tooth pitch, root fillet radius, and more.
Gear dimensions are determined in accordance with their specifications, such as Module (m), Number of teeth (z), Pressureangle (α), and Profile shift coefficient (x). 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.
Calculation Example. What is the pitch size (p) of the Gear with module m = 3 ? p = πm = 9.4248. CP (Circular Pitch) Circular Pitch (CP) denotes the reference pitch (p). For instance, you can produce gears at an exact integral value, such as CP5/CP10/CP15/CP20. Transformation from CP to Module m = CP / π (2.2) Calculation Example.
Gear Pitch Calculator: Find Pitch Diameter, Gear Blank Outer Diameter (OD), and Root Diameter. 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.
Spur Gear design formula for geometry, pitch, tooth clearance and critical functional data. Circular Pitches and Equivalent Diametral Pitches Table
This gear calculator software also handles gear calculations of various types of gears such as spur gears, worm gears, gear racks, bevel gears, internal gears, screw gears, etc.
Module Calculation︱Gear Rack. Module is the unit of size to indicate how big or small a gear pinion is. It is the ratio of the reference diameter of the gear pinion divided by the number of teeth. Thus the formula of module calculation is as following: Module ( M ) = Reference Diameter ( R d ) / Number of Tooth ( N t )
