Uses the ISO system (e.g., 9g for shafts, 9H for hubs) to control backlash and interference. 2. Core Geometric Formulas
DIN 5480 covers a range of modules (e.g., 0.5 — 10+), with standardized tooth counts and corresponding diameters to suit different torque levels and shaft sizes. Selection depends on required torque capacity, material strength, and manufacturing method.
Part 1: Principles (Cloudfront) : Contains the fundamental principles, basic rack profiles, and calculation steps.
This part details the design features of tools used in manufacturing, such as hobs, pinion-type cutters, and broaches. The data ensures that these tools can accurately produce splines that conform to the standard.
Nominal dimensions and space widths for module sizes from 0.5 to 10.
db = dref * cos(α) Alpha (pressure angle) is typically 30° for DIN 5480 (rarely 37.5° or 45°). PDF trap: Some PDFs erroneously show 20° pressure angle – this is part of DIN 5480.
