, meaning the flanks transmit torque and center the shaft and hub. Module Range: Typically covers modules from with 6 to 82 teeth. Fit System: Uses a combination of a Tolerance Class (e.g., 5 to 12) and a Deviation Series (letters). External Splines (Shaft): Lower case letters (e.g., for slip fits, for line-on-line). Internal Splines (Hub): Upper case letters (e.g., for slip fits, for standard line-on-line). ANSI Webstore Understanding the PDF Structure
Because involute teeth are curved, machinists cannot easily use standard calipers to measure tooth thickness. DIN 5480-15 specifies the "Measurement over Pins" (for shafts) or "Measurement between Pins" (for hubs). Two precision pins/balls of a specific diameter ( DMcap D sub cap M ) are placed in opposing tooth spaces. Din 5480 Pdf
To recreate a spline profile from a DIN 5480 PDF data sheet, you need to understand the relationship between the diameters. Here are the fundamental equations for a standard spline: For External Splines (Shaft) Pitch Diameter ( ): Major Diameter ( ): Minor Diameter ( ): For Internal Splines (Hub) Major Diameter ( ): Minor Diameter ( ):
Splined connections are widely used in various industries, including: This public link is valid for 7 days
Here is how to decode that string based on the standard documentation:

Designated with lowercase letters (e.g., 9g , 8f , 7h ). Letters like f and g provide clearance, ensuring ease of assembly.
The complete DIN 5480 standard is not a single document; it is divided into several parts, each covering a specific aspect of spline design and manufacturing. When looking for a DIN 5480 PDF, you will typically find it split into the following sections:
