Ensure your calculation for the form diameter ( ) provides enough clearance for the mating part's tip.
Change the tolerance class from 7h to 9h; if your "Measurement Over Pins" doesn't change, your formula for tooth thickness deviation is broken. Conclusion
To build or use a calculator effectively, you must understand the core inputs required: The primary sizing factor. Module ( ): Determines the size of the teeth. Pressure Angle ( ): Standard DIN 5480 uses a 30° pressure angle . Number of Teeth ( ): Must be an integer.
DIN 5480 is unique because it uses specific profile shifts to maintain constant reference diameters. Your Excel sheet must calculate the profile shift coefficient (
