Din 5480 Spline Dimensions Pdf -

DIN 5480 standard defines involute splines based on reference diameters ( d sub cap B ) that are independent of the module ( ). It is strictly limited to splines with a 30 raised to the composed with power pressure angle Doppler Gear Key Dimensioning Parameters When reading a DIN 5480 specification (e.g., DIN 5480 W 120 x 3 x 38 x 8f ), the dimensions are broken down as follows: : Indicates the type of spline. stands for "Welle" (Shaft/External) and stands for "Nabe" (Hub/Internal). Reference Diameter ( d sub cap B : The first number (e.g., : The second number (e.g., ), which determines the tooth size. Number of Teeth ( : The third number (e.g., Tolerance Class : The final alphanumeric code (e.g., Reference PDFs and Technical Resources

For a given module, the reference diameter determines the number of teeth. Example for : din 5480 spline dimensions pdf

| Module (m) | Number of teeth (z) | Pitch diameter (d) | Tooth thickness (s) | | --- | --- | --- | --- | | 1 | 10 | 10 mm | 1.57 mm | | 1.5 | 12 | 18 mm | 2.36 mm | | 2 | 16 | 32 mm | 3.14 mm | DIN 5480 standard defines involute splines based on

is the tolerance class (5–12); f is the deviation (lower case for shafts, upper case for hubs). Fundamental Dimension Formulas Calculations for DIN 5480 involve profile shifts ( Reference Diameter ( d sub cap B : The first number (e
