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.
KHK offers online software to compute gear sizes, strengths, forces, tooth forms, backlash conversions, etc. and produce gear drawings in dxf format. Users can input various parameters related to gear calculations and download the results or the drawings.
To use the calculator, enter the module and number of teeth and the rest of the table should automatically update. The image below the table gives an indication of what the gear might look like. If you put out-of-range values into any of the fields, it'll probably look wrong!
