: Unlike straight splines, DIN 5482 uses an involute curve, which provides self-centering and higher load capacity. Module ( ): Determines the size of the teeth. Number of Teeth ( ): The total count of splines on the circumference. Pressure Angle ( ): Typically 30∘30 raised to the composed with power for these involute profiles. Reference Diameter ( ): Calculated as .
: Commonly used in gear pumps from manufacturers like Casappa . Involute splines under this standard are characterized by
Like most metric gear standards, it uses the system to define tooth size. Common modules range from 1 to 8. 3. Profile Fit
