Din 5480 Spline Dimensions Pdf Verified 'link' May 2026
The DIN 5480 standard defines the principles for splined connections with involute flanks based on reference diameters. Revised in 2006, the current standard consolidates sixteen previous parts into four core sections to simplify technical specifications. Core Principles of DIN 5480
Number of teeth (z): The number of teeth on the spline can vary from 6 to 20, depending on the application and design requirements.
Module (m): The module, also known as the diametral pitch, is the ratio of the pitch diameter to the number of teeth. DIN 5480 defines modules from 0.5 to 5 mm.
Pressure angle (α): The pressure angle, also known as the angle of obliquity, is the angle between the tooth profile and the line perpendicular to the spline axis. The standard pressure angle is 30° or 37.5°.
Spline length (L): The spline length is the axial length of the spline, which can vary depending on the application.
Deviation (Hubs - Upper Case): Letters F–G are slip fits; H is the standard line-on-line fit. Verified Resources and Standards din 5480 spline dimensions pdf verified
- Module Range: 0.5 to 10 mm
- Reference Diameter: Not a round number; it is based on the modulus x number of teeth.
- Profile Shift (x*m): Unlike American standards, DIN 5480 uses a specific profile shift to ensure the major diameter fits standard bearing bore tolerances.
- Common Verification Check: For a correct DIN 5480 spline, the major diameter is always smaller than the reference diameter (opposite of ANSI B92.1).
