Din - 5480 Pdf
DIN 5480
is the German industrial standard for involute splines based on reference diameters. It defines the geometry, dimensions, and tolerances for spline joints where the teeth have an involute profile, similar to gear teeth, ensuring high torque transmission and self-centering capabilities. Core Technical Specifications Pressure Angle : Strictly limited to 30° .
Types of Splined Connections According to DIN 5480
Number of Teeth (z)
: Calculated based on the module and reference diameter. Din 5480 Pdf
The older DIN 5482 standard is largely obsolete but still exists in legacy equipment. : You typically select a size from a table that "fits". DIN 5480 is the German industrial standard for
- Gauging: Go/no-go spline ring gauges or plug gauges per DIN 5480-2.
- Measurement over pins (Mdk): The standard provides formulas and tables for calculating the theoretical measurement over two pins of specified diameter. Do not use general ISO 4156 pin formulas – they differ due to the reference diameter offset.
- Runout: Total composite runout (Fd) is measured on a spline roll checker.
