Trying to determine torque capacity of a DIN 5480 spline

Trying to determine torque capacity of a DIN 5480 spline

(OP)
I'm tryin to determine the torque capacity of a 120 mm DIN 5480 external spline, W120x5x30x22x8g.  From what I've been able to gather I need to refer to the standard DIN 5466-2 but I can't find anywhere to obtain it?  Not even on the DIN website.  If anyone is able to help the spline length is 90 mm and the spline material is 4340.

RE: Trying to determine torque capacity of a DIN 5480 spline

ike2010,

Machinery's Handbook gives a simplified approach for spline torque capacity. It was developed by Dudley.  You'll just need to convert your units of measure.

If you want a spline fatigue life value for a given torque and number of load cycles, that problem becomes more complex.

Good luck.
Terry
