Din 5482 Spline Dimensions Calculator «2027»

Note: Exact addendum/dedendum values and root/clearance depend on the DIN 5482 series and manufacturing tolerances; use the standard tables for final machining dimensions.

An automated dimensional calculator processes inputs to find the precise machining tolerances for both the external spline (shaft) and internal spline (hub/bore). Step-by-Step Calculation Logic:

A robust calculator for this standard must go beyond simple look-up tables. It typically processes several key inputs to generate a full manufacturing data sheet: Involute Splines according to DIN 5482 - HEXAGON Software din 5482 spline dimensions calculator

Before using a calculator, engineers must understand the standard. (Deutsches Institut für Normung) specifies "Straight-sided splines for light and medium duty." It is notably different from DIN 5480 (involute splines) because its tooth flanks are straight lines radiating from the center.

Specified to ensure proper fit (clearance or interference) between the shaft and hub. Digital Calculation and Tools It typically processes several key inputs to generate

Generates 2D (DXF) or 3D (STEP/IGES) files for CAD software.

A: To identify a mystery spline, you typically need the Number of Teeth ($z$), the Outer Diameter (Tip), and the Root Diameter. By plugging these into a calculator, you can reverse-engineer the Module and Pressure Angle. Digital Calculation and Tools Generates 2D (DXF) or

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

| Part Number | Teeth (z) | Module (m) | Outer Diameter (mm) | Root Diameter (mm) | Common Application | | :--- | :--- | :--- | :--- | :--- | :--- | | | 9 | ≈ 1.9 | 17.0 | 14.0 | Hydraulic pumps | | 20x17 | 12 | ≈ 1.6 | 20.0 | 17.0 | Fluid power equipment | | 25x22 | 12 | ≈ 2.1 | 25.0 | 22.0 | Drive couplings | | 35x31 | 18 | ≈ 1.9 | 35.0 | 31.0 | Gearboxes | | 80x74 | 19 | ≈ 4.2 | 80.0 (major) | 74.0 (minor) | Hydraulic motor connection |

The ratio of the pitch diameter to the number of teeth (e.g., 1.5, 2, 3).
