Stress Concentration Factors for DIN5480 splines

Stress Concentration Factors for DIN5480 splines

Stress Concentration Factors for DIN5480 splines

(OP)
Is there a commonly accepted method for sizing DIN splines? Or are there any published stress concentration factors? The spline I have in mind is W140x5x26x8f.

I have copies of standard design procedures and stress factors for "American" splines (AGMA, ANSI, etc...)such as given in the Machinery's Handbook, but not for DIN splines.

Applying the Mach. Handbook methods to this DIN spline seems to give results that are too conservative -- expecially when contrasted with the torque rating of the mating gearbox.

Thanks Cory. As you probably know, the link you provided was to a demo version of a DIN spline design program. The demo version only works for a reference diameter of 120mm. So one option is I could buy the program in order to analyze the spline that I'm concerned with.

However, the program mentioned DIN 5466, which (I found out) is the standard for calculating spline load capacity. So I'm going to try to track that down first. Thanks again.
