The DIN 5480 series is built on specific geometric principles that distinguish it from other spline standards like ISO 4156 or ANSI B92.2M.
A critical aspect of DIN 5480 is how the shaft and hub are centered (aligned) relative to each other. The standard defines three types: din 5480
is a comprehensive German industrial standard that defines the geometry, dimensions, and tolerances for involute splined connections . Unlike simple keys or pins, splines provide a robust method for connecting shafts and hubs to transmit high torque while ensuring precise axial and angular alignment. The DIN 5480 series is built on specific
: The standard is strictly limited to splines with a 30° pressure angle . Unlike simple keys or pins, splines provide a
: The teeth follow an involute curve, which allows for smoother load distribution and easier manufacturing compared to straight-sided splines.
