    Involute Spline Reverse Engineering

    The root diameter is actually smaller than what it should be. Remeasured several times at 13.80mm (only have a caliper). That could explain why the pins does not go in deep enough. I still don't know how to reproduce those splines? Please help.

    Involute Spline Reverse Engineering

    Just realized the internal spline over measurement was wrong. The pin is too small to make contact with both flanks. It touches the root diameter. Hence a small error. The pin I used is 1.75mm. Why is that? Shouldn't be like that?

    Involute Spline Reverse Engineering

    Edit: I'll go to 9H. 7H is unnecessarily tight for the application.

    Involute Spline Reverse Engineering

    Thank you. It indeed looks like that. However the diameter over pins are different. I measured the shaft and hub diameters over pins to be as follow: 17.23mm@2.5mm 10.56mm@1.76mm I thought the error was too large, hence the attempt to change the profile shift (Kisssoft matches it...

    Involute Spline Reverse Engineering

    Thanks a lot. I double-checked the base pitch. If my assumptions were right; it should be 2.72mm. I measured, using the method you recommend, 2.68mm, a result that seems reasonably closed, considering the relative size of the shaft. So the variation is diameter over pins would be related to...

    Involute Spline Reverse Engineering

    First post. I just did a reverse engineering of a splined hub I need to replicate (different driveline). Certainly metric, I deduced that the spline were 30 degrees, with a module of 1mm and 12 teeth. I measured the shaft and hub diameters over pins according to DIN5480 (2.5mm for the shaft...
