To help tailor this information or provide the exact values you need, could you share a bit more context? Let me know:

indicates an Internal Spline (Hub/Bore). W indicates an External Spline (Shaft). 120 Reference Diameter ( The nominal dimension around which the spline is designed ( 3 The pitch module, which dictates tooth size ( 38 Number of Teeth ( The total count of splines around the circumference ( 9H or 8f Tolerance Class

DIN 5480 is the German standard for involute splines based on reference diameters. Unlike other standards that use the pitch diameter as a starting point, DIN 5480 centers the design on the outside diameter of the shaft, making it easier to match with standard bearings and seals.

Typically designated with capital letters (e.g., 9H , 7H ). The 9H class is the most common industry standard for general machinery. din 5480 spline dimensions pdf

The standard is divided into several parts, with serving as the foundation for principles and basic rack profiles. Pressure Angle: Strictly 30°. Module (m): Range from 0.5 to 10 mm. Number of Teeth (z): Range from 6 to 82 teeth.

) to allow for easy integration with standard rolling bearing sizes. Pressure Angle: Standardized at 30∘30 raised to the composed with power Module Range: Typically covers Tooth Count: Standard ranges from

Designated by uppercase letters (e.g., G , H ). Position H results in a minimum space equal to the nominal size.

DIN 5480 is the German standard for , widely used in mechanical engineering for high torque transmission and precise alignment. Unlike other standards that rely on the major or minor diameter, DIN 5480 uses a reference diameter ( dBd sub cap B 120 Reference Diameter ( The nominal dimension around

: "W" (Welle) denotes an external shaft; "N" (Nabe) denotes an internal hub.

The precision of the spline is defined by its tolerance class, which directly impacts the backlash in the joint.

Comprehensive Guide to DIN 5480 Spline Dimensions DIN 5480 is the international standard for involute splines based on module sizes. It governs straight cylindrical involute splines with a 30° pressure angle and a reference diameter. This system uses flank centering, meaning the flanks of the spline teeth transmit the torque and locate the mating parts.

: The Reference Diameter (not the major or minor diameter). 3 : The Module , which indicates the tooth size. 38 : The Number of Teeth .
