Din 5482 Spline Dimensions Calculator |work|

The calculator outputs both basic theoretical dimensions and actual dimensional limits (tolerances). Key outputs include:

Because DIN 5482 does not strictly scale every profile linearly based on the module alone, calculators rely on lookup tables derived from the standard. Below is a reference dataset for common DIN 5482 sizes to validate your calculator outputs: Standard Designation Number of Teeth ( Shaft Major Shaft Minor D2cap D sub 2 20 x 17 22 x 19 25 x 22 28 x 25 30 x 27 35 x 31 40 x 36 45 x 41 50 x 45 4.

The is an indispensable engineering tool used to determine the geometry, tolerances, and mating clearances of involute splines with a 30∘30 raised to the composed with power

Unlike modern standards that use module and number of teeth as the primary defining factors, DIN 5482 identifies splines using a combination of the approximate nominal diameter ( ) and the module ( The fundamental geometry relies on these core variables: Module ( The calculator outputs both basic theoretical dimensions and

Calculating the dimensions of an involute spline is significantly more complex than calculating a standard spur gear. Because the teeth are involute curves, you cannot simply measure a "pitch diameter" with calipers.

For quick reference, here are some common sizes calculated using a standard DIN 5482 profile: Size Designation Module (m) Major Dia (Shaft) Meas. Over Pins ( Macap M sub a 10 x 14 x 17 12 x 15 x 18 15 x 17 x 20 20 x 22 x 25 Measuring Over Pins (Span Measurement) d2=d1−(2×h)d sub 2

DIN 5482 distinguishes two series:

Advanced calculators generate target over-pin measurements (M🌍 pins) and wire sizes, essential for gear measurement and CNC grinding.
