Involute tooth profile, which ensures smooth engagement and uniform load distribution. Pressure Angle: Fixed at 30°.
The second number (e.g., 22) represents the approximate minor diameter of the profile. din 5482 spline standard file type pdf77
If you need this standard for a restoration or repair job, do not rely on free, illegal copies. Purchase the authentic document—it is far cheaper than scrapping a mis-machined spline shaft. Involute tooth profile, which ensures smooth engagement and
Centering is always . The major and minor diameters have larger clearances. This ensures that torque transmission is not compromised by eccentricity in the non‑critical diameters. If you need this standard for a restoration

: Operates on a reference diameter system independent of the module. Tooling is universal, meaning a single 30° hob tool can cut any number of teeth within its specific module range, dramatically dropping manufacturing costs. Din 5482 Spline Standard - sciphilconf.berkeley.edu
